CONTEXT: Prior qualitative work with internally displaced persons in war-affected northern Uganda showed significant mental health and psychosocial problems. OBJECTIVE: To assess effect of locally feasible interventions on depression, anxiety, and conduct problem symptoms among adolescent survivors of war and displacement in northern Uganda. DESIGN, SETTING, AND PARTICIPANTS: A randomized controlled trial from May 2005 through December 2005 of 314 adolescents (aged 14-17 years) in 2 camps for internally displaced persons in northern Uganda. INTERVENTIONS: Locally developed screening tools assessed the effectiveness of interventions in reducing symptoms of depression and anxiety, ameliorating conduct problems, and improving function among those who met study criteria and were randomly allocated (105, psychotherapy-based intervention [group interpersonal psychotherapy]; 105, activity-based intervention [creative play]; 104, wait-control group [individuals wait listed to receive treatment at study end]). Intervention groups met weekly for 16 weeks. Participants and controls were reassessed at end of study. MAIN OUTCOME MEASURES: Primary measure was a decrease in score (denoting improvement) on a depression symptom scale. Secondary measures were improvements in scores on anxiety, conduct problem symptoms, and function scales. Depression, anxiety, and conduct problems were assessed using the Acholi Psychosocial Assessment Instrument with a minimum score of 32 as the lower limit for clinically significant symptoms (maximum scale score, 105). RESULTS: Difference in change in adjusted mean score for depression symptoms between group interpersonal psychotherapy and control groups was 9.79 points (95% confidence interval [CI], 1.66-17.93). Girls receiving group interpersonal psychotherapy showed substantial and significant improvement in depression symptoms compared with controls (12.61 points; 95% CI, 2.09-23.14). Improvement among boys was not statistically significant (5.72 points; 95% CI, -1.86 to 13.30). Creative play showed no effect on depression severity (-2.51 points; 95% CI, -11.42 to 6.39). There were no statistically different improvements in anxiety in either intervention group. Neither intervention improved conduct problem or function scores. CONCLUSIONS: Both interventions were locally feasible. Group interpersonal psychotherapy was effective for depression symptoms among adolescent girls affected by war and displacement. Other interventions should be investigated to assist adolescent boys in this population who have symptoms of depression. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00280319.

BACKGROUND: Strengthening the capacity of midwives to deliver high-quality maternal and newborn health services has been highlighted as a priority by global health organisations. To support low-income and middle-income countries (LMICs) in their decisions about investments in health, we aimed to estimate the potential impact of midwives on reducing maternal and neonatal deaths and stillbirths under several intervention coverage scenarios. METHODS: For this modelling study, we used the Lives Saved Tool to estimate the number of deaths that would be averted by 2035, if coverage of health interventions that can be delivered by professional midwives were scaled up in 88 countries that account for the vast majority of the world's maternal and neonatal deaths and stillbirths. We used four scenarios to assess the effects of increasing the coverage of midwife-delivered interventions by a modest amount (10% every 5 years), a substantial amount (25% every 5 years), and the amount needed to reach universal coverage of these interventions (ie, to 95%); and the effects of coverage attrition (a 2% decrease every 5 years). We grouped countries in three equal-sized groups according to their Human Development Index. Group A included the 30 countries with the lowest HDI, group B included 29 low-to-medium HDI countries, and group C included 29 medium-to-high HDI countries. FINDINGS: We estimated that, relative to current coverage, a substantial increase in coverage of midwife-delivered interventions could avert 41% of maternal deaths, 39% of neonatal deaths, and 26% of stillbirths, equating to 2·2 million deaths averted per year by 2035. Even a modest increase in coverage of midwife-delivered interventions could avert 22% of maternal deaths, 23% of neonatal deaths, and 14% of stillbirths, equating to 1·3 million deaths averted per year by 2035. Relative to current coverage, universal coverage of midwife-delivered interventions would avert 67% of maternal deaths, 64% of neonatal deaths, and 65% of stillbirths, allowing 4·3 million lives to be saved annually by 2035. These deaths averted would be particularly concentrated in the group B countries, which currently account for a large proportion of the world's population and have high mortality rates compared with group C. INTERPRETATION: Midwives can help to substantially reduce maternal and neonatal mortality and stillbirths in LMICs. However, to realise this potential, midwives need to have skills and competencies in line with recommendations from the International Confederation of Midwives, to be part of a team of sufficient size and skill, and to work in an enabling environment. Our study highlights the potential of midwives but there are many challenges to the achievement of this potential. If increased coverage of midwife-delivered interventions can be achieved, health systems will be better able to provide effective coverage of essential sexual, reproductive, maternal, newborn, and adolescent health interventions.

BACKGROUND: Hypertension is an important contributor to global burden of disease and mortality, and is a growing public health problem in sub-Saharan Africa. However, most sub-Saharan African countries lack detailed countrywide data on hypertension and other non-communicable diseases (NCD) risk factors that would provide benchmark information for design of appropriate interventions. We analyzed blood pressure data from Uganda's nationwide NCD risk factor survey conducted in 2014, to describe the prevalence and distribution of hypertension in the Ugandan population, and to identify the associated factors. METHODS: The NCD risk factor survey drew a countrywide sample stratified by the four regions of the country, and with separate estimates for rural and urban areas. The World Health Organization's STEPs tool was used to collect data on demographic and behavioral characteristics, and physical and biochemical measurements. Prevalence rate ratios (PRR) using modified Poison regression modelling was used to identify factors associated with hypertension. RESULTS: Of the 3906 participants, 1033 were classified as hypertensive, giving an overall prevalence of 26.4%. Prevalence was highest in the central region at 28.5%, followed by the eastern region at 26.4%, western region at 26.3%, and northern region at 23.3%. Prevalence in urban areas was 28.9%, and 25.8% in rural areas. The differences between regions, and between rural-urban areas were not statistically significant. Only 7.7% of participants with hypertension were aware of their high blood pressure. The prevalence of pre-hypertension was also high at 36.9%. The only modifiable factor found to be associated with hypertension was higher body mass index (BMI). Compared to participants with BMI less than 25 kg/m2, prevalence was significantly higher among participants with BMI between 25 to 29.9 kg/m2 with an adjusted PRR = 1.46 [95% CI = 1.25-1.71], and even higher among obese participants (BMI ≥ 30 kg/m2) with an adjusted PRR = 1.60 [95% CI = 1.29-1.99]. The un-modifiable factor found to be associated with hypertension was older age with an adjusted PRR of 1.02 [95% CI = 1.02-1.03] per yearly increase in age. CONCLUSIONS: The prevalence of hypertension in Uganda is high, with no significant differences in distribution by geographical location. Only 7.7% of persons with hypertension were aware of their hypertension, indicating a high burden of undiagnosed and un-controlled high blood pressure. Thus a big percentage of persons with hypertension are at high risk of hypertension-related cardiovascular NCDs.

BACKGROUND: Uganda is currently implementing the International Health Regulations (IHR[2005]) within the context of Integrated Disease Surveillance and Response (IDSR). The IHR(2005) require countries to assess the ability of their national structures, capacities, and resources to meet the minimum requirements for surveillance and response. This report describes the results of the assessment undertaken in Uganda. METHODS: We conducted a descriptive cross-sectional assessment using the protocol developed by the World Health Organisation (WHO). The data collection tools were adapted locally and administered to a convenience sample of HR(2005) stakeholders, and frequency analyses were performed. RESULTS: Ugandan national laws relevant to the IHR(2005) existed, but they did not adequately support the full implementation of the IHR(2005). Correspondingly, there was a designated IHR National Focal Point (NFP), but surveillance activities and operational communications were limited to the health sector. All the districts (13/13) had designated disease surveillance offices, most had IDSR technical guidelines (92%, or 12/13), and all (13/13) had case definitions for infectious and zoonotic diseases surveillance. Surveillance guidelines were available at 57% (35/61) of the health facilities, while case definitions were available at 66% (40/61) of the health facilities. The priority diseases list, surveillance guidelines, case definitions and reporting tools were based on the IDSR strategy and hence lacked information on the IHR(2005). The rapid response teams at national and district levels lacked food safety, chemical and radio-nuclear experts. Similarly, there were no guidelines on the outbreak response to food, chemical and radio-nuclear hazards. Comprehensive preparedness plans incorporating IHR(2005) were lacking at national and district levels. A national laboratory policy existed and the strategic plan was being drafted. However, there were critical gaps hampering the efficient functioning of the national laboratory network. Finally, the points of entry for IHR(2005) implementation had not been designated. CONCLUSIONS: The assessment highlighted critical gaps to guide the IHR(2005) planning process. The IHR(2005) action plan should therefore be developed to foster national and international public health security.

BACKGROUND: Uganda's poor maternal health indicators have resulted from weak maternal health services delivery, including access to quality family planning, skilled birth attendance, emergency obstetric care, and postnatal care for mothers and newborns. This paper investigated the predictors of maternal health services (MHS) utilization characterized as: desirable, moderate and undesirable. METHODS: We used a sample of 1728 women of reproductive ages (15-49), who delivered a child a year prior to the 2011 UDHS survey. A multinomial logistic regression model was used to analyze the relative contribution of the various predictors of ideal maternal health services package utilization. Andersen's Behavioral Model of Health Services Utilization guided the selection of covariates in the regression model. RESULTS: Women with secondary and higher education were more likely to utilize the desirable maternal health care package (RRR = 4.5; 95% CI = 1.5-14.0), compared to those who had none (reference = undesirable MHS package). Women who lived in regions outside Kampala, Uganda's capital, were less likely to utilize the desirable package of maternal health services (Eastern--RRR = 0.2, CI = 0.1-0.5; Western--RRR = 0.3, CI = 0.1-0.8; Central--RRR = 0.3, CI = 0.1-0.8; Northern--RRR = 0.4, CI = 0.2-1.0). Women from the richest households were more likely to utilize the desirable maternal health services package (RRR = 1.9; 95% CI = 1.0-3.7). Residence in rural areas, being Moslem and being married reduced a woman's chances of utilizing moderate maternal health care services. CONCLUSIONS: Utilization of maternal health services varied greatly by demographic and socio-economic characteristics. Women with a secondary and higher education, and those of higher income levels, were more likely to utilize the ideal maternal health services package. Therefore, there is need to formulate policies and design maternal health services programs that target the socially marginalized women.

In 1998, the WHO African region adopted a strategy called Integrated Disease Surveillance and Response (IDSR). Here, we present the current status of IDSR implementation; and provide some future perspectives for enhancing the IDSR strategy in Africa. In 2017, we used two data sources to compile information on the status of IDSR implementation: a pretested rapid assessment questionnaire sent out biannually to all countries and quarterly compilation of data for two IDSR key performance indicators (KPI). The first KPI measures country IDSR performance and the second KPI tracks the number of countries that the WHO secretariat supports to scale up IDSR. The KPI data for 2017 were compared with a retrospective baseline for 2014. By December 2017, 44 of 47 African countries (94%) were implementing IDSR. Of the 44 countries implementing IDSR, 40 (85%) had initiated IDSR training at subnational level; 32 (68%) had commenced community-based surveillance; 35 (74%) had event-based surveillance; 33 (70%) had electronic IDSR; and 32 (68%) had a weekly/monthly bulletin for sharing IDSR data. Thirty-two countries (68%) had achieved the timeliness and completeness threshold of at least 80% of the reporting units. However, only 12 countries (26%) had the desired target of at least 90% IDSR implementation coverage at the peripheral level. After 20 years of implementing IDSR, there are major achievements in the indicator-based surveillance systems. However, major gaps were identified in event-based surveillance. All African countries should enhance IDSR everywhere.

INTRODUCTION: The Ebola virus, belonging to the family of filoviruses, was first recognized in 1976 when it caused concurrent outbreaks in Yambuku in the Democratic Republic of Congo (DRC), and in the town of Nzara in Sudan. Both countries share borders with Uganda. A total of 425 cases and 224 deaths attributed to Ebola haemorrhagic fever (EHF) were recorded in Uganda in 2000/01. Although there was delayed detection at the community level, prompt and efficient outbreak investigation led to the confirmation of the causative agent on 14 October 2000 by the National Institute of Virology in South Africa, and the subsequent institution of control interventions. CONTROL INTERVENTIONS: Public health interventions to contain the epidemic aimed at minimizing transmission in the health care setting and in the community, reducing the case fatality rate due to the epidemic, strengthening co-ordination for the response and building capacity for on-going surveillance and control. Co-ordination of the control interventions was organized through the Interministerial Committee, National Ebola Task Force, District Ebola Task Forces, and the Technical Committees at national and district levels. The World Health Organization (WHO) under the Global Outbreak Alert and Response Network co-ordinated the international response. The post-outbreak control interventions addressed weaknesses prior to outbreak detection and aimed at improving preparations for future outbreak detection and response. Challenges to control efforts included inadequate and poor quality protective materials, deaths of health workers, numerous rumors and the rejection of convalescent cases by members of the community. CONCLUSIONS: This was recognized as the largest reported outbreak of EHF in the world. Control interventions were very successful in containing the epidemic. The community structures used to contain the epidemic have continued to perform well after containment of the outbreak, and have proved useful in the identification of other outbreaks. This was also the first outbreak response co-ordinated by the WHO under the Global Outbreak Alert and Response Network, a voluntary organization recently created to co-ordinate technical and financial resources to developing countries during outbreaks.

While multiple studies have found that children affected by war are at increased risk for a range of mental health problems, little research has investigated how mental health problems are perceived locally. In this study we used a previously developed rapid ethnographic assessment method to explore local perceptions of mental health problems among children and adults from the Acholi ethnic group displaced by the war in northern Uganda. We conducted 45 free list interviews and 57 key informant interviews. The rapid assessment approach appears to have worked well for interviewing caretakers and children aged 10-17 years. We describe several locally defined syndromes: two tam/par/kumu (depression and dysthymia-like syndromes), ma lwor (a mixed anxiety and depression-like syndrome), and a category of conduct problems referred to as kwo maraco/gin lugero. The descriptions of these local syndromes were similar to western mood, anxiety and conduct disorders, but included culture-specific elements.

OBJECTIVE: To document the effects of the abolition of user fees on utilization of health services in Uganda with emphasis on poor and vulnerable groups. METHODS: A longitudinal study using quantitative and qualitative methods was carried out in 106 health facilities across the country. Health records were reviewed to determine trends in overall utilization patterns and use among vulnerable groups. A modification of wealth ranking as defined by the Uganda Poverty Participatory Assessment Project was used to categorize households by socio-economic status in order to compare utilization by the poor against that of other socio-economic groups. FINDINGS: There was a marked increase in utilization in all population groups that was fluctuating in nature. The increase in utilization varied from 26% in public referral facilities in 2001, rising to 55% in 2002 compared with 2000. The corresponding figures for the lower level facilities were 44% and 77%, respectively. Increase in utilization among the poor was more than for other socio-economic categories. Women utilized health services more than men both before and after cost-sharing. Higher increases in utilization were noted among the over-five age group compared with the under-fives. There were no increases in utilization for preventive and inpatient services. With respect to quality of care, there were fewer drug stock-outs in 2002 compared with 2000 and 2001. There was no deterioration of other indicators such as cleanliness, compound maintenance and staff availability reported. CONCLUSION: The study suggests that there is a financial barrier created by cost-sharing that decreases access to services, especially among the poor in Uganda. However, further studies are needed to clarify issues of utilization by age and gender.

The World Health Organization (WHO) undertook the development of a rapid guide on the use of chest imaging in the diagnosis and management of coronavirus disease 2019 (COVID-19). The rapid guide was developed over 2 months by using standard WHO processes, except for the use of “rapid reviews” and online meetings of the panel. The evidence review was supplemented by a survey of stakeholders regarding their views on the acceptability, feasibility, impact on equity, and resource use of the relevant chest imaging modalities (chest radiography, chest CT, and lung US). The guideline development group had broad expertise and country representation. The rapid guide includes three diagnosis recommendations and four management recommendations. The recommendations cover patients with confirmed or who are suspected of having COVID-19 with different levels of disease severity, throughout the care pathway from outpatient facility or hospital entry to home discharge. All recommendations are conditional and are based on low certainty evidence (n = 2), very low certainty evidence (n = 2), or expert opinion (n = 3). The remarks accompanying the recommendations suggest which patients are likely to benefit from chest imaging and what factors should be considered when choosing the specific imaging modality. The guidance offers considerations about implementation, monitoring, and evaluation, and also identifies research needs. Published under a CC BY 4.0 license.

BACKGROUND: The rationale for promotion of family planning (FP) to delay conception after a recent birth is a best practice that can lead to optimal maternal and child health outcomes. Uptake of postpartum family planning (PPFP) remains low in sub-Saharan Africa. However, little is known about how pregnant women arrive at their decisions to adopt PPFP. METHODS: We used 3298 women of reproductive ages 15-49 from the 2011 UDHS dataset, who had a birth in the 5 years preceding the survey. We then applied both descriptive analyses comprising Pearson's chi-square test and later a binary logistic regression model to analyze the relative contribution of the various predictors of uptake of modern contraceptives during the postpartum period. RESULTS: More than a quarter (28%) of the women used modern family planning during the postpartum period in Uganda. PPFP was significantly associated with primary or higher education (OR=1.96; 95% CI=1.43-2.68; OR=2.73; 95% CI=1.88-3.97 respectively); richest wealth status (OR=2.64; 95% CI=1.81-3.86); protestant religion (OR=1.27; 95% CI=1.05-1.54) and age of woman (OR=0.97, 95% CI=0.95-0.99). In addition, PPFP was associated with number of surviving children (OR=1.09; 95 % CI=1.03-1.16); exposure to media (OR=1.30; 95% CI=1.05-1.61); skilled birth attendance (OR=1.39; 95% CI=1.12-1.17); and 1-2 days timing of post-delivery care (OR=1.68; 95% CI=1.14-2.47). CONCLUSIONS: Increasing reproductive health education and information among postpartum women especially those who are disadvantaged, those with no education and the poor would significantly improve PPFP in Uganda.

BACKGROUND: HIV self-testing allows HIV testing at any place and time and without health workers. HIV self-testing may thus be particularly useful for female sex workers (FSWs), who should test frequently but face stigma and financial and time barriers when accessing healthcare facilities. METHODS AND FINDINGS: We conducted a cluster-randomized controlled health systems trial among FSWs in Kampala, Uganda, to measure the effect of 2 HIV self-testing delivery models on HIV testing and linkage to care outcomes. FSW peer educator groups (1 peer educator and 8 participants) were randomized to either (1) direct provision of HIV self-tests, (2) provision of coupons for free collection of HIV self-tests in a healthcare facility, or (3) standard of care HIV testing. We randomized 960 participants in 120 peer educator groups from October 18, 2016, to November 16, 2016. Participants' median age was 28 years (IQR 24-32). Our prespecified primary outcomes were self-report of any HIV testing at 1 month and at 4 months; our prespecified secondary outcomes were self-report of HIV self-test use, seeking HIV-related medical care and ART initiation. In addition, we analyzed 2 secondary outcomes that were not prespecified: self-report of repeat HIV testing-to understand the intervention effects on frequent testing-and self-reported facility-based testing-to quantify substitution effects. Participants in the direct provision arm were significantly more likely to have tested for HIV than those in the standard of care arm, both at 1 month (risk ratio [RR] 1.33, 95% CI 1.17-1.51, p < 0.001) and at 4 months (RR 1.14, 95% CI 1.07-1.22, p < 0.001). Participants in the direct provision arm were also significantly more likely to have tested for HIV than those in the facility collection arm, both at 1 month (RR 1.18, 95% CI 1.07-1.31, p = 0.001) and at 4 months (RR 1.03, 95% CI 1.01-1.05, p = 0.02). At 1 month, fewer participants in the intervention arms had sought medical care for HIV than in the standard of care arm, but these differences were not significant and were reduced in magnitude at 4 months. There were no statistically significant differences in ART initiation across study arms. At 4 months, participants in the direct provision arm were significantly more likely to have tested twice for HIV than those in the standard of care arm (RR 1.51, 95% CI 1.29-1.77, p < 0.001) and those in the facility collection arm (RR 1.22, 95% CI 1.08-1.37, p = 0.001). Participants in the HIV self-testing arms almost completely replaced facility-based testing with self-testing. Two adverse events related to HIV self-testing were reported: interpersonal violence and mental distress. Study limitations included self-reported outcomes and limited generalizability beyond FSWs in similar settings. CONCLUSIONS: In this study, HIV self-testing appeared to be safe and increased recent and repeat HIV testing among FSWs. We found that direct provision of HIV self-tests was significantly more effective in increasing HIV testing among FSWs than passively offering HIV self-tests for collection in healthcare facilities. HIV self-testing could play an important role in supporting HIV interventions that require frequent HIV testing, such as HIV treatment as prevention, behavior change for transmission reduction, and pre-exposure prophylaxis.

BACKGROUND: Hydroxyurea has proven safety, feasibility, and efficacy in children with sickle cell anemia in sub-Saharan Africa, with studies showing a reduced incidence of vaso-occlusive events and reduced mortality. Dosing standards remain undetermined, however, and whether escalation to the maximum tolerated dose confers clinical benefits that outweigh treatment-related toxic effects is unknown. METHODS: In a randomized, double-blind trial, we compared hydroxyurea at a fixed dose (approximately 20 mg per kilogram of body weight per day) with dose escalation (approximately 30 mg per kilogram per day). The primary outcome was a hemoglobin level of 9.0 g or more per deciliter or a fetal hemoglobin level of 20% or more after 24 months. Secondary outcomes included the incidences of malaria, vaso-occlusive crises, and serious adverse events. RESULTS: Children received hydroxyurea at a fixed dose (94 children; mean [±SD] age, 4.6±1.0 years) or with dose escalation (93 children; mean age, 4.8±0.9 years); the mean doses were 19.2±1.8 mg per kilogram per day and 29.5±3.6 mg per kilogram per day, respectively. The data and safety monitoring board halted the trial when the numbers of clinical events were significantly lower among children receiving escalated dosing than among those receiving a fixed dose. At trial closure, 86% of the children in the dose-escalation group had reached the primary-outcome thresholds, as compared with 37% of the children in the fixed-dose group (P<0.001). Children in the dose-escalation group had fewer sickle cell-related adverse events (incidence rate ratio, 0.43; 95% confidence interval [CI], 0.34 to 0.54), vaso-occlusive pain crises (incidence rate ratio, 0.43; 95% CI, 0.34 to 0.56), cases of acute chest syndrome or pneumonia (incidence rate ratio, 0.27; 95% CI, 0.11 to 0.56), transfusions (incidence rate ratio, 0.30; 95% CI, 0.20 to 0.43), and hospitalizations (incidence rate ratio, 0.21; 95% CI, 0.13 to 0.34). Laboratory-confirmed dose-limiting toxic effects were similar in the two groups, and there were no cases of severe neutropenia or thrombocytopenia. CONCLUSIONS: Among children with sickle cell anemia in sub-Saharan Africa, hydroxyurea with dose escalation had superior clinical efficacy to that of fixed-dose hydroxyurea, with equivalent safety.

1976· Transactions of the Royal Society of Tropical Medicine and Hygiene140doi:10.1016/0035-9203(76)90128-0

In a BCG vaccination trial in an area of Uganda endemic for Mycobacterium ulcerans disease ("Buruli Ulcer"), 8,856 persons were examined for the disease in mid-1970 and tuberculin tested; BCG was given by intradermal injection to a random 50% of all those with negative, low or middle grade tuberculin reactions; Twelve months later the study group was re-examined for M. ulcerans lesions and, subsequently, new cases of the disease were detected, using a hospital registration system, to December 1974. One hundred and forty-nine patients with onset since July 1970 were thus ascertained and BCG was found to offer an overall protection of 47% against the disease, similar to that observed in a previous smaller trial by the Uganda Buruli Group (UBG, 1969). However, the protective effect was confined to those with tuberculin reactions of less than 4 mm before vaccination and was apparent only in the first year of the study. BCG offered no additional protection to those with previous M. ulcerans disease or an existing BCG scar at entry into the trial, although both these groups appeared to be protected against the disease, the protective effects being 88% and 82% respectively. An initial tuberculin reaction of 4 mm (or greater) offered some protection against the disease (37%). Lesions developing in the vaccinated group, or in those with initial tuberculin reactions of 4 mm or more, were smaller than those in unvaccinated persons. No relationship was found between the protective effect of BCG and either the prevalence of persons with evidence of previous M. ulcerans disease in different geographical areas, or the incidence of new cases in different areas during the first year of the study. A decline in the incidence was observed over the study period. The findings are consistent with BCG producing only short-lasting protection against M. ulcerans disease. However, long-lasting protection and a delay in onset of the disease in vaccinated persons, as suggested by the UBG in 1969, cannot be excluded on the basis of the data currently available from this trial.

INTRODUCTION: Hoima, one of the largest districts in mid- western Uganda, has persistently performed poorly with low immunization coverage, high immunization drop outs rates and repeated outbreaks of vaccine preventable diseases especially measles. The objectives of this study were to evaluate the state of immunization services and to identify the gaps in immunization health systems that contribute to low uptake and completion of immunization schedules in Hoima District. METHODS: This was a cross sectional mixed methods study, utilizing both qualitative and quantitative approaches. A situation analysis of the immunization services was carried out using in-depth interviews with vaccinators, focus group discussions and key informant interviews with ethno-videography. Secondary data was sourced from records at headquarters and vaccination centres within Hoima District. The quantitative component utilized cluster random sampling with sample size estimated using the World Health Organization's 30 cluster sampling technique. RESULTS: A total of 311 caretaker/child pairs were included in the study. Immunization completion among children of age at least 12 months was 95% for BCG, 96% for OPV0, 93% for DPT1, 84.5% for DPT2, 81% for DPT3 and 65.5% for measles vaccines. Access to immunization centres is difficult due to poor road terrain, which affects effectiveness of outreach program, support supervision, mentorship and timely delivery of immunization program support supplies especially refrigerator gas and vaccines. Some facilities are under-equipped to effectively support the program. Adverse Events Following Immunization (AEFI) identification, reporting and management is poorly understood. CONCLUSION: Immunization services in Hoima District require urgent improvement in the following areas: vaccine supply, expanding service delivery points, more health workers, transport and tailored mechanisms to ensure adequate communication between health workers and caretakers.

BACKGROUND: Ebola haemorrhagic fever (EHF) is infamous for its high case-fatality proportion (CFP) and the ease with which it spreads among contacts of the diseased. We describe the course of the EHF outbreak in Masindi, Uganda, in the year 2000, and report on response activities. METHODS: We analysed surveillance records, hospital statistics, and our own observations during response activities. We used Fisher's exact tests for differences in proportions, t-tests for differences in means, and logistic regression for multivariable analysis. RESULTS: The response to the outbreak consisted of surveillance, case management, logistics and public mobilisation. Twenty-six EHF cases (24 laboratory confirmed, two probable) occurred between October 21st and December 22nd, 2000. CFP was 69% (18/26). Nosocomial transmission to the index case occurred in Lacor hospital in Gulu, outside the Ebola ward. After returning home to Masindi district the index case became the origin of a transmission chain within her own extended family (18 further cases), from index family members to health care workers (HCWs, 6 cases), and from HCWs to their household contacts (1 case). Five out of six occupational cases of EHF in HCWs occurred after the introduction of barrier nursing, probably due to breaches of barrier nursing principles. CFP was initially very high (76%) but decreased (20%) due to better case management after reinforcing the response team. The mobilisation of the community for the response efforts was challenging at the beginning, when fear, panic and mistrust had to be countered by the response team. CONCLUSIONS: Large scale transmission in the community beyond the index family was prevented by early case identification and isolation as well as quarantine imposed by the community. The high number of occupational EHF after implementing barrier nursing points at the need to strengthen training and supervision of local HCWs. The difference in CFP before and after reinforcing the response team together with observations on the ward suggest a critical role for intensive supportive treatment. Collecting high quality clinical data is a priority for future outbreaks in order to identify the best possible FHF treatment regime under field conditions.

The Global Plan Towards the Elimination of New HIV Infections Among Children by 2015 and Keeping Their Mothers Alive (Global Plan), which was launched in 2011, set a series of ambitious targets, including a reduction of new HIV infections among children by 90% by 2015 (from a baseline year of 2009) and AIDS-related maternal mortality by 50% by 2015. To reach these targets, the Global Plan called for unprecedented investments in the prevention of mother-to-child transmission of HIV (PMTCT), innovative new approaches to service delivery, immense collective effort on the programmatic and policy fronts, and importantly, a renewed focus on data collection and use. We provide an overview of major achievements in monitoring and evaluation across Global Plan countries and highlight key challenges and innovative country-driven solutions using PMTCT program data. Specifically, we describe the following: (1) Uganda's development and use of a weekly reporting system for PMTCT using short message service technology that facilitates real-time monitoring and programmatic adjustments throughout the transition to a "treat all" approach for pregnant and breastfeeding women living with HIV (Option B+); (2) Uganda's work to eliminate parallel reporting systems while strengthening the national electronic district health information system; and (3) how routine PMTCT program data in Nigeria can be used to estimate HIV prevalence at the local level and address a critical gap in local descriptive epidemiologic data to better target limited resources. We also identify several ongoing challenges in data collection, analysis, and use, and we suggest potential solutions.

Inadequate health financing is one of the major challenges health systems in low-income countries currently face. Health financing reforms are being implemented with an increasing interest in policies that abolish user fees. Data from three nationally representative surveys conducted in Uganda in 1999/2000, 2002/03 and 2005/06 were used to investigate the impact of user fee abolition on the attainment of universal coverage objectives. An increase in illness reporting was noted over the three surveys, especially among the poorer quintiles. An increase in utilization was registered in the period immediately following the abolition of user fees and was most pronounced in the poorest quintile. Overall, there was an increase in utilization in both public and private health care delivery sectors, but only at clinic and health centre level, not at hospitals. Our study shows important changes in health-care-seeking behaviour. In 2002/03, the poorest population quintile started using government health centres more often than private clinics whereas in 1999/2000 private clinics were the main source of health care. The richest quintile has increasingly used private clinics. Overall, it appears that the private sector remains a significant source of health care. Following abolition of user fees, we note an increase in the use of lower levels of care with subsequent reductions in use of hospitals. Total annual average expenditures on health per household remained fairly stable between the 1999/2000 and 2002/03 surveys. There was, however, an increase of US$21 in expenditure between the 2002/03 and 2005/06 surveys. Abolition of user fees improved access to health services and efficiency in utilization. On the negative side is the fact that financial protection is yet to be achieved. Out-of-pocket expenditure remains high and mainly affects the poorer population quintiles. A dual system seems to have emerged where wealthier population groups are switching to the private sector.

BACKGROUND: In Ethiopia there is no complete registration system to measure disease burden and risk factors accurately. In this study, the 2015 global burden of diseases, injuries and risk factors (GBD) data were used to analyse the incidence, prevalence and mortality rates of malaria in Ethiopia over the last 25 years. METHODS: GBD 2015 used verbal autopsy surveys, reports, and published scientific articles to estimate the burden of malaria in Ethiopia. Age and gender-specific causes of death for malaria were estimated using cause of death ensemble modelling. RESULTS: The number of new cases of malaria declined from 2.8 million [95% uncertainty interval (UI) 1.4-4.5 million] in 1990 to 621,345 (95% UI 462,230-797,442) in 2015. Malaria caused an estimated 30,323 deaths (95% UI 11,533.3-61,215.3) in 1990 and 1561 deaths (95% UI 752.8-2660.5) in 2015, a 94.8% reduction over the 25 years. Age-standardized mortality rate of malaria has declined by 96.5% between 1990 and 2015 with an annual rate of change of 13.4%. Age-standardized malaria incidence rate among all ages and gender declined by 88.7% between 1990 and 2015. The number of disability-adjusted life years lost (DALY) due to malaria decreased from 2.2 million (95% UI 0.76-4.7 million) in 1990 to 0.18 million (95% UI 0.12-0.26 million) in 2015, with a total reduction 91.7%. Similarly, age-standardized DALY rate declined by 94.8% during the same period. CONCLUSIONS: Ethiopia has achieved a 50% reduction target of malaria of the millennium development goals. The country should strengthen its malaria control and treatment strategies to achieve the sustainable development goals.

BACKGROUND: Young people in Uganda face various sexual and reproductive health risks, especially those living in urban slums. The aim of this study was to examine factors associated with comprehensive categories of sexual and reproductive health, including sexual behaviours; sexual education and access to contraceptive services; family planning; prevention of STDs; sexual consent as a right; gender based violence; as well as HIV testing, counselling, disclosure and support. METHODS: The study was cross-sectional in design and was carried out in July 2014 in Makindye and Nakawa Divisions of Kampala City, Uganda. Using systematic random sampling, data were collected on 663 participants aged between 13 and 24 years in Kampala's urban slums. RESULTS: Sixty two percent of participants reported having ever had sex and the mean age of sexual debut was 16 years (95%CI: 15.6, 16.4 years, range: 5-23 years). The odds of reporting ever having had sexual intercourse were higher among respondents living alone (OR: 2.75; 95%CI: 1.35, 5.61; p<0.01) than those living in a nuclear family. However, condom use was only 54%. The number of sexual partners in the last 12 months preceding the survey averaged 1.8 partners (95%CI: 1.7, 1.9; range 1-4) with 18.1% reporting an age gap of 10 years or older. More than three quarters (80.6%) of sexually active participants reported that their first sexual encounter was consensual, suggesting that most young people are choosing when they make their sexual debut. Low prevalence of willing first sexual intercourse was associated with younger age (OR = 0.48, 95%CI: 0.25, 0.90, p<0.05), having a disability (OR = 0.40, 95%CI: 0.16, 0.98, p<0.05), living with non-relatives (OR = 0.44, 95%CI: 0.16, 0.97, p<0.05), and being still at school (OR = 0.29, 95%CI: 0.12, 0.67, p<0.01). These results remained significant after adjusting for covariates, except for disability and the age of participants. The proportion of unwilling first sexual intercourse was significantly higher among women for persuasion (13.2% vs. 2.4%, p<0.001), being tricked (7.1% vs 2.9%, p<0.05) and being forced or raped (9.9% vs 4.4%, p<0.05) than men. A high level of sexual abuse emerged from the data with 34.3% affirming that it was alright for a boy to force a girl to have sex if he had feelings for her; 73.3% affirming that it was common for strangers and relatives to force young females to have sexual intercourse with them without consent; 26.3% indicating that it was sometimes justifiable for a boy to hit his girlfriend, as long as they loved each other. CONCLUSION: This study has explored current sexual practice among young people in a specific part of urban Kampala. Young people's sexual and reproductive health remains a challenge in Uganda. To address these barriers, a comprehensive and harmonised sexual and reproductive health system that is youth friendly and takes into account local socio-cultural contexts is urgently needed.
