RESUMO
INTRODUCTION: Many female teenagers in low-resource settings conceive, of which half are unplanned and end in many deaths in sub-Saharan Africa, accounting for the majority of the cases. Teenage pregnancy is associated sometimes with poor maternal, newborn, and child deaths. OBJECTIVES: The aim of the study was to determine the prevalence, maternal obstetric outcomes, and factors associated with poor maternal obstetric outcomes among teenage mothers delivering at Mbarara Regional Referral Hospital. METHODS: This was a cross-sectional study carried out in a maternity ward at Mbarara Regional Referral Hospital, where 9,200 mothers deliver annually. All the women coming in for the delivery of their babies were consecutively approached for inclusion in the study. The women were enrolled in the post-delivery ward after delivery and interviewed with pretested questionnaires to capture the sociodemographic, obstetric, and medical profiles of the mothers. Factors were significant if the p-value was <0.05. Results: Out of the 327 participants, the majority were rural dwellers (68.5%), married (75.8%), attained primary education (69.4%), had not used contraception (89%), and had had a planned pregnancy (63.3%). The prevalence of adverse maternal obstetrical events was 59.9%. The HIV-positive rate was 4.9%, and about half of the participants had delivered by cesarean section (41.6%). The participants' mean age was 18.4 years and SD 1.1. The mean number of antenatal care contacts attended was 4.59 and SD 1.9. The adverse maternal outcomes included episiotomy (30.9%), perineal tear (18.7%), premature rupture of membranes (10.1%), placenta abruption (5.2%), and pre-eclampsia/eclampsia (4%). Having a cesarean delivery was found to significantly reduce the occurrence of adverse maternal obstetric events among the participants by 97% (adjusted odds ratio (aOR) (95% CI) of 0.03 (0.02-0.06), p-value<0.001). Having a prior history of a miscarriage was significantly associated with the occurrence of adverse maternal obstetrical events among the participants (aOR (95% CI) of 6.55 (1.46-29.42), p-value0.014). CONCLUSIONS: Slightly more than half of the teenage mothers had adverse maternal obstetrical outcomes, and a history of a miscarriage in previous pregnancies was significantly associated with adverse maternal obstetrical outcomes. Having a cesarean delivery was found to significantly reduce the occurrence of adverse maternal obstetric events among the participants. Teenage mothers are at a high risk of adverse maternal obstetrical outcomes, and close antepartum and intrapartum surveillance is recommended.
RESUMO
Introduction A large number of teenagers in low-resource settings experience pregnancy, with a significant number of these cases happening in sub-Saharan Africa. Teenage pregnancy is associated with unique physical and psychological experiences. Objective To explore the lived experiences of teenage mothers delivering at a tertiary referral hospital in southwestern Uganda. Methods This qualitative study used focus group discussions (FGDs) with teenage mothers in Kasese and Bundibugyo districts in Uganda. We purposively sampled 32 teenage mothers attending a tertiary referral hospital who had been pregnant at least once and had given birth. Sociodemographic information was obtained, and FGDs were conducted to capture the teenagers' experiences transitioning to motherhood. An inductive content analytic approach was used to analyze data. Results The mean age of the participants was 18.4 (standard deviation [SD], 1.2) years, with the majority (22, 68.8%) being rural dwellers, married (23, 71.9%), unemployed (21, 65.6%), and having attained primary education (23, 71.9%). Teenage mothers' lived experiences were characterized by shattered dreams, concerns about changes in their body size and shape, abandonment and neglect by family members and spouses, considerations of terminating the pregnancy, forced early marriages, family stereotypes, and engaging in sex for survival. The process of transitioning to motherhood occurred along with resilience post-pregnancy and supportive environments from their loved ones, which enabled them to accept reality and care for their children. Conclusions The lived experiences of teenage mothers demonstrated social pressures, fear of abandonment, and poverty as major influences on their mindset and behavior. Further research to gain a comprehensive understanding of the challenges encountered by teenage mothers will aid the development of culturally appropriate strategies to reduce teenage pregnancy and improve perinatal outcomes.
RESUMO
BACKGROUND: In Uganda, village health workers (VHWs) manage childhood illness under the integrated community case management (iCCM) strategy. Care is provided for malaria, pneumonia, and diarrhoea in a community setting. Currently, there is limited evidence on the cost-effectiveness of iCCM in comparison to health facility-based management for childhood illnesses. This study examined the cost-effectiveness of the management of childhood illness using the VHW-led iCCM against health facility-based services in rural south-western Uganda. METHODS: Data on the costs and effectiveness of VHW-led iCCM versus health facility-based services for the management of childhood illness was collected in one sub-county in rural southwestern Uganda. Costing was performed using the ingredients approach. Effectiveness was measured as the number of under-five children appropriately treated. The Incremental Cost-Effectiveness Ratio (ICER) was calculated from the provider perspective. RESULTS: Based on the decision model for this study, the cost for 100 children treated was US$628.27 under the VHW led iCCM and US$87.19 for the health facility based services, while the effectiveness was 77 and 71 children treated for VHW led iCCM and health facility-based services, respectively. An ICER of US$6.67 per under five-year child treated appropriately for malaria, pneumonia and diarrhoea was derived for the provider perspective. CONCLUSION: The health facility based services are less costly when compared to the VHW led iCCM per child treated appropriately. The VHW led iCCM was however more effective with regard to the number of children treated appropriately for malaria, pneumonia and diarrhoea. Considering the public health expenditure per capita for Uganda as the willingness to pay threshold, VHW led iCCM is a cost-effective strategy. VHW led iCCM should, therefore, be enhanced and sustained as an option to complement the health facility-based services for treatment of childhood illness in rural contexts.

BACKGROUND: Pre-referral treatment aims to stabilize the child's condition before transferring them to a higher level of healthcare. This study explored pre-referral treatment for diarrhea, malaria and pneumonia in children U5. The study aims to assess pre-referral treatment practices among community health workers (CHWs) for children aged 2 to 59 months diagnosed with malaria, diarrhea, and pneumonia. METHODS: Conducted in 2023, this study employed a quantitative retrospective analysis of secondary data gathered from March 2014 to December 2018. Among the subjects, 171 patients received pre-referral treatment, serving as the foundation for categorical data analysis, presenting proportions and 95% confidence intervals across different categories. RESULTS: In this cohort, 90 (53%) of the 177 children U5 were male, and age distribution showed 39 (23%), 70 (41%), and 62 (36%) in the 2-11 months, 12-35 months, and 36-60 months categories, respectively. Rapid Diagnostic Test (RDT) malaria results indicated a negative outcome in 83(60%) and positive in 55 (40%) of cases. Symptomatically, 45 (26%) had diarrhea, 52 (30%) exhibited fast breathing, and 109 (63%) presented with fever. Furthermore, 59 (35%) displayed danger signs, while 104 (61%) sought medical attention within 24 h. CONCLUSION: The study analyzed a sample of 171 children under 5 years old to assess various characteristics and variables related to pre-referral treatment. The findings reveal notable proportions in gender distribution, age categories, RDT results, presence of diarrhea, fast breathing, fever, danger signs, and timely medical visits. The results highlight the need to strengthen pre-referral treatment interventions and enhance iCCM programs.

BACKGROUND: Malaria epidemics result from extreme precipitation and flooding, which are increasing with global climate change. Local adaptation and mitigation strategies will be essential to prevent excess morbidity and mortality. METHODS: We investigated the spatial risk of malaria infection at multiple timepoints after severe flooding in rural western Uganda employing longitudinal household surveys measuring parasite prevalence and leveraging remotely sensed information to inform spatial models of malaria risk in the 3 months after flooding. RESULTS: We identified clusters of malaria risk emerging in areas (1) that showed the greatest changes in Normalized Difference Vegetation Index from pre- to postflood and (2) where residents were displaced for longer periods of time and had lower access to long-lasting insecticidal nets, both of which were associated with a positive malaria rapid diagnostic test result. The disproportionate risk persisted despite a concurrent chemoprevention program that achieved high coverage. CONCLUSIONS: The findings enhance our understanding not only of the spatial evolution of malaria risk after flooding, but also in the context of an effective intervention. The results provide a "proof of concept" for programs aiming to prevent malaria outbreaks after flooding using a combination of interventions. Further study of mitigation strategies-and particularly studies of implementation-is urgently needed.

BACKGROUND: In integrated community case management (iCCM) care, community health workers (CHWs) provide home-based management of fever, diarrhea and fast breathing for children aged <5 y. The iCCM protocol recommends that children with danger signs for severe illness are referred by CHWs to health facilities within their catchment area. This study examines the management of danger signs by CHWs implementing iCCM in a rural context. METHODS: A retrospective observational study that examined clinical records for all patients with danger signs evaluated by CHWs from March 2014 to December 2018 was conducted. RESULTS: In total, 229 children aged <5 y had been recorded as having a danger sign during 2014-2018. Of these children, 56% were males with a mean age of 25 (SD 16.9) mo, among whom 78% were referred by the CHWs as per the iCCM protocol. The age category of 12 to 35 mo had the highest numbers of prereferred and referred cases (54% and 46%, respectively). CONCLUSIONS: CHWs play a key role in early symptomatic detection, prereferral treatment and early referral of children aged <5 y. Danger signs among children aged <5 y, if left untreated, can result in death. A high proportion of the children with danger signs were referred as per the iCCM protocol. Continuous CHW training is emphasized to reduce the number of referral cases that are missed. More studies need to focus on children aged 12-35 mo and why they are the most referred category. Policymakers should occasionally revise iCCM guidelines to detail the types of danger signs and how CHWs can address these.

BACKGROUND: Malaria risk is not uniform across relatively small geographic areas, such as within a village. This heterogeneity in risk is associated with factors including demographic characteristics, individual behaviours, home construction, and environmental conditions, the importance of which varies by setting, making prediction difficult. This study attempted to compare the ability of statistical models to predict malaria risk at the household level using either (i) free easily-obtained remotely-sensed data or (ii) results from a resource-intensive household survey. METHODS: The results of a household malaria survey conducted in 3 villages in western Uganda were combined with remotely-sensed environmental data to develop predictive models of two outcomes of interest (1) a positive ultrasensitive rapid diagnostic test (uRDT) and (2) inpatient admission for malaria within the last year. Generalized additive models were fit to each result using factors from the remotely-sensed data, the household survey, or a combination of both. Using a cross-validation approach, each model's ability to predict malaria risk for out-of-sample households (OOS) and villages (OOV) was evaluated. RESULTS: Models fit using only environmental variables provided a better fit and higher OOS predictive power for uRDT result (AIC = 362, AUC = 0.736) and inpatient admission (AIC = 623, AUC = 0.672) compared to models using household variables (uRDT AIC = 376, Admission AIC = 644, uRDT AUC = 0.667, Admission AUC = 0.653). Combining the datasets did not result in a better fit or higher OOS predictive power for uRDT results (AIC = 367, AUC = 0.671), but did for inpatient admission (AIC = 615, AUC = 0.683). Household factors performed best when predicting OOV uRDT results (AUC = 0.596) and inpatient admission (AUC = 0.553), but not much better than a random classifier. CONCLUSIONS: These results suggest that residual malaria risk is driven more by the external environment than home construction within the study area, possibly due to transmission regularly occurring outside of the home. Additionally, they suggest that when predicting malaria risk the benefit may not outweigh the high costs of attaining detailed information on household predictors. Instead, using remotely-sensed data provides an equally effective, cost-efficient alternative.

BACKGROUND: Village Health Workers (VHWs) in Uganda provide treatment for the childhood illness of malaria, pneumonia, and diarrhoea through the integrated community case management (iCCM) strategy. Under the strategy children under five years receive treatment for these illnesses within 24 h of onset of illness. This study examined promptness in seeking treatment from VHWs by children under five years with malaria, pneumonia, and diarrhoea in rural southwestern Uganda. METHODS: In August 2022, a database containing information from the VHWs patient registers over a 5-year study period was reviewed (2014-2018). A total of 18,430 child records drawn from 8 villages of Bugoye sub-county, Kasese district were included in the study. Promptness was defined a caregiver seeking treatment for a child from a VHW within 24 h of onset of illness. RESULTS: Sixty-four percent (64%) of the children included in the study sought treatment promptly. Children with fever had the highest likelihood of seeking prompt treatment (aOR = 1.93, 95% CI 1.80-2.06, p < 0.001) as compared to those with diarrhoea (aOR = 1.43, 95% CI 1.32-1.52, p < 0.001) and pneumonia (aOR = 1.33, 95% CI 1.24-1.42, p < 0.001). CONCLUSION: The findings provide further evidence that VHWs play a critical role in the treatment of childhood illness in rural contexts. However, the proportion of children seeking prompt treatment remains below the target set at the inception of the iCCM strategy, in Uganda. There is a need to continually engage rural communities to promote modification of health-seeking behaviour, particularly for children with danger signs. Evidence to inform the design of services and behaviour change communication, can be provided through undertaking qualitative studies to understand the underlying reasons for decisions about care-seeking in rural settings. Co-design with communities in these settings may increase the acceptability of these services.

This article details the study protocol for a double-blind, randomized placebo-controlled trial to determine the effectiveness of permethrin-treated baby wraps to prevent Plasmodium falciparum malaria infection in children 6-24 months of age. Participating mother-infant dyads will be randomized to receive either a permethrin-treated or a sham-treated wrap, known locally as a "lesu." After a baseline home visit, during which time all participants will receive new long-lasting insecticidal nets, participants will attend scheduled clinic visits every two weeks for a period of 24 weeks. In the event of an acute febrile illness or other symptoms that may be consistent with malaria (e.g., poor feeding, headache, malaise), participants will be instructed to present to their respective study clinic for evaluation. The primary outcome of interest is the incidence of laboratory-confirmed, symptomatic malaria in participating children. Secondary outcomes of interest include: (1) change in children's hemoglobin levels; (2) change in children's growth parameters; (3) prevalence of asymptomatic parasitemia in children; (4) hospitalization for malaria in children; (5) change in the mother's hemoglobin level; and (6) clinical malaria in the mother. Analyses will be conducted using a modified intent-to-treat approach, with woman-infant dyads who attend one or more clinic visits analyzed according to the arm to which they were randomly assigned. This is the first use of an insecticide-treated baby wrap for prevention of malaria in children. The study began recruitment in June 2022 and is ongoing. ClinicalTrials.gov Identifier: NCT05391230, Registered 25 May 2022.

Barriers continue to limit access to viral load (VL) monitoring across sub-Saharan Africa adversely impacting control of the HIV epidemic. The objective of this study was to determine whether the systems and processes required to realize the potential of rapid molecular technology are available at a prototypical lower-level (i.e., level III) health center in rural Uganda. In this open-label pilot study, participants underwent parallel VL testing at both the central laboratory (i.e., standard of care) and on-site using the GeneXpert HIV-1 assay. The primary outcome was the number of VL tests completed each clinic day. Secondary outcomes included the number of days from sample collection to receipt of result at clinic and the number of days from sample collection to patient receipt of the result. From August 2020 to July 2021, we enrolled a total of 242 participants. The median number of daily tests performed on the Xpert platform was 4, (IQR = 2-7). Time from sample collection to result was 51 days (IQR = 45-62) for samples sent to the central laboratory and 0 days (IQR = 0-0.25) for the Xpert assay conducted at the health center. However, few participants elected to receive results by one of the expedited options, which contributed to similar time-to-patient between testing approaches (89 versus 84 days, p = 0.07). Implementation of a rapid, near point-of-care VL assay at a lower-level health center in rural Uganda appears feasible, but interventions to promote rapid clinical response and influence patient preferences about result receipt require further study.

RESUMO
BACKGROUND: The control of malaria, pneumonia, and diarrhoea is important for the reduction in morbidity and mortality among children under 5 years. Uganda has adopted the Integrated Community Case Management strategy using Community Health Workers (CHWs) to address this challenge. The extent and trend of these three conditions managed by the CHWs are not well documented. This study was done to describe the epidemiology and trends of the three common illnesses treated by the CHWs in Bugoye Sub-County in rural Uganda. METHODS: A retrospective review of monthly morbidity data for children less than 5 years of age for the period April 2014-December 2018 for CHWs in rural Bugoye Sub-County in Kasese district, Uganda was done. The total number reviewed was 18,430 records. The data were analysed using STATA version 14. RESULTS: In total male were 50.2% of the sample, pneumonia was the highest cause of illness among the infants (< 1 year), while malaria was the highest among the children 1 year-59 months. Infection with a single illness was the commonest recorded cause of presentation but there were some children recorded with multiple illnesses. All the CHWs were managing the three common illnesses among children under 5 years. The trend of the three common illnesses was changing from malaria to pneumonia being the commonest. Children aged 12-24 months and 25-59 months were at 2.1 times (95% CI 1.7-2.4) and 5.2 times (95% CI 4.6-5.9), respectively, more likely to get malaria but less likely to get pneumonia and diarrhoea. CONCLUSION: Community Health Workers in rural Uganda are contributing significantly to the management of all the three commonest illnesses among under-5 years-old children. The trend of the commonest illness is changing from malaria to pneumonia. Children under 1 year are at a higher risk of getting pneumonia and diarrhoea and at a lower risk of getting malaria.

OBJECTIVE: Integrated community case management (iCCM) of childhood illness in Uganda involves protocol-based care of malaria, pneumonia and diarrhoea for children under 5 years old. This study assessed volunteer village health workers' (VHW) ability to provide correct iCCM care according to the national protocol and change in their performance over time since initial training. SETTING: VHWs affiliated with the Ugandan national programme provide community-based care in eight villages in Bugoye Subcounty, a rural area in Kasese District. The first cohort of VHWs began providing iCCM care in March 2013, the second cohort in July 2016. PARTICIPANTS: All children receiving iCCM care in 18 430 clinical encounters occurring between April 2014 and December 2018. PRIMARY AND SECONDARY OUTCOME MEASURES: The descriptive primary outcome measure was the proportion of patients receiving overall correct care, defined as adherence to the iCCM protocol for the presenting condition (hereafter quality of care). The analytic primary outcome was change in the odds of receiving correct care over time, assessed using logistic regression models with generalised estimating equations. Secondary outcome measures included a set of binary measures of adherence to specific elements of the iCCM protocol. Preplanned and final measures were the same. RESULTS: Overall, VHWs provided correct care in 74% of clinical encounters. For the first cohort of VHWs, regression modelling demonstrated a modest increase in quality of care until approximately 3 years after their initial iCCM training (OR 1.022 per month elapsed, 95% CI 1.005 to 1.038), followed by a modest decrease thereafter (OR 0.978 per month, 95% CI 0.970 to 0.986). For the second cohort, quality of care was essentially constant over time (OR 1.007 per month, 95% CI 0.989 to 1.025). CONCLUSION: Quality of care was relatively constant over time, though the trend towards decreasing quality of care after 3 years of providing iCCM care requires further monitoring.

INTRODUCTION: Achieving the Open defecation free (ODF) status remains a major challenge in Uganda, yet it contributes significantly to child health improvement. Literature on social, cultural and behavioral aspects that influence the ODF status in rural Uganda is limited. The study therefore, explored perceived factors influencing the ODF status in rural South Western Uganda. METHODS: An exploratory study employing qualitative techniques and based on deductive analysis between month December 2020 and January 2021 was conducted. Seven Focus Group Discussions (FGDs and three Key Informant Interviews (KIs) were conducted in Kabale District, southwestern Uganda. Focus Group Discussion participants were mothers and fathers having children of 2 years and below while KIIs included local community leaders and health extension workers. Data was analyzed using a categorization matrix derived from the Risks, Attitudes, Norms, Abilities, and Self-regulation (RANAS) model which is comprised of contextual and psychological factors. Text was further categorized into high and low statements for attainment of ODF status. RESULTS: The contextual factors influencing the Open Defecation Free status behavior included; farming activities far from home, financial constraints, rainy seasons, collapsible soft soils, and alcohol use. Psychological factors influencing ODF status included; perceived health risk for typhoid disease, low perceived severity for lack of ODF components, negative attitude of less value attached to ODF components, and a feeling of time wastage practicing ODF status behavior. The perception that the community has the ability to attain the ODF status was high. Although, the capability to maintain ODF was low when it comes to replacement of ODF component if stolen or destroyed. CONCLUSION: Open Defecation Free status is influenced by contextual and psychological factors. Therefore, it's crucial for sanitation promotors to always identify such context specific factors in order to design sanitation and hygiene promotion interventions to address the ODF free status related challenges.

Globally, billions of people still lack access to safe water, including basic drinking water services, particularly in sub-Saharan Africa. We analyzed water quality for improved water sources and associated factors in Kibuku district, Eastern Uganda. The mixed-methods study employed included; water quality analysis, a questionnaire survey, and key informant interviews conducted in the months of April-June 2020. A total of 249 improved water sources were sampled for analysis of bacteriological quality, pH, and electrical conductivity. This was followed by a sanitary and people's attitudes survey at all the water sources visited. Among the water sources, 62.3% deep boreholes, 63.5% public tap stands, 14.3% rain-water harvesting tanks, and 28.6% protected springs had zero thermotolerant coliforms with 63.8% having acceptable pH levels (6.5-8.5) and 35.3% having acidic levels (less than 6.4). Furthermore, 96.3% deep boreholes, 99.1% public tap stands, all (100%) rain-water harvesting tanks, and 50% protected springs had their turbidity levels in the acceptable range (less than 5NTUs). Additionally, only 22.1% of improved water sources had electrical conductivity in the acceptable range (less than 300 microSiemens). Among the 249 participants, majority (91.2%) had low knowledge levels about various methods that can be used in improving the quality of water. Generally, water sources had poor quality of water which was attributed to agricultural activities, dirty water collection containers, and poor attitude to water chlorination. The Ministry of Health, Ministry of Water and Environment, and other agencies need to design sustainable and feasible models for water treatment for low resourced setting.
RESUMO
BACKGROUND: Progress against malaria has stalled and may even be slipping backwards in high-burden countries. This is due to a range of factors including insecticide resistance and mosquito feeding behaviours that limit contact with widely-employed interventions including long-lasting insecticidal nets and indoor-residual spraying. Thus, further innovations in malaria control are urgently needed. METHODS: The pilot was a randomized, placebo-controlled pilot study of permethrin-treated baby wraps-known locally as lesus-in children 6-18 months of age at a single site in rural western Uganda. Fifty mother-infant pairs were assigned to permethrin-treated or untreated lesus in a 1:1 allocation. Participants and clinical staff were blinded to group assignments through use of sham treatment and re-treatment of lesus. Participants attended scheduled clinic visits every 2 weeks for a total 12 weeks. The primary outcome of interest was the safety of the intervention, assessed as changes in the frequency of use, rates of discontinuation, and incidence of adverse events, such as skin rash. Secondary outcomes included acceptability and feasibility of the intervention as measured through participant satisfaction and completion of study activities, respectively. RESULTS: Overall, rates of retention and participation were relatively high with 86.0% (43 of 50) of participants completing all scheduled visits, including 18 (75.0%) and 25 (96.2%) in the intervention and control arms respectively. By the conclusion of the 12-week follow-up period, one adverse event (0.35 events per 100 person-weeks, one-sided 95% CI 0.0-1.65) was reported. Satisfaction with the lesu was high in both groups. In each study arm, there were five incident RDT positive results, but the only PCR-positive results were observed in the control group (n = 2). CONCLUSIONS: Permethrin-treated baby wraps were well-tolerated and broadly acceptable. Adverse events were infrequent and mild. These findings support future trials seeking to determine the efficacy of treated wraps to prevent P. falciparum malaria infection in young children as a complementary tool to existing household-based interventions.

BACKGROUND: Malaria epidemics are a well-described phenomenon after extreme precipitation and flooding. Yet, few studies have examined mitigation measures to prevent post-flood malaria epidemics. METHODS: We evaluated a malaria chemoprevention program implemented in response to severe flooding in western Uganda. Childrenâ aged ≤12 years from 1 village were eligible to receive 3 monthly rounds of dihydroartemisinin-piperaquine (DP). Two neighboring villages served as controls. Malaria cases were defined as individuals with a positive rapid diagnostic test result as recorded in health center registers. We performed a difference-in-differences analysis to estimate changes in the incidence and test positivity of malaria between intervention and control villages. RESULTS: A total of 554 children received at least 1 round of chemoprevention, with 75% participating in at least 2 rounds. Compared with control villages, we estimated a 53.4% reduction (adjusted rate ratio [aRR], 0.47; 95% confidence interval [CI]: .34-.62; Pâ <â .01) in malaria incidence and a 30% decrease in the test positivity rate (aRR,â 0.70; 95% CI: .50-.97; Pâ =â .03) in the intervention village in the 6 months post-intervention. The impact was greatest among children who received the intervention, but decreased incidence was also observed in older children and adults (aRR,â 0.57; 95% CI: .38-.84; Pâ <â .01). CONCLUSIONS: Three rounds of chemoprevention with DP delivered under pragmatic conditions reduced the incidence of malaria after severe flooding in western Uganda. These findings provide a proof-of-concept for the use of malaria chemoprevention to reduce excess disease burden associated with severe flooding.

BACKGROUND: Long-lasting insecticidal nets (LLINs) remain a cornerstone of malaria control, but strategies to sustain universal coverage and high rates of use are not well-defined. A more complete understanding of context-specific factors, including transmission intensity and access to health facilities, may inform sub-district distribution approaches and tailored messaging campaigns. METHODS: A cross-sectional survey of 2190 households was conducted in a single sub-county of western Uganda that experiences highly variable malaria transmission intensity. The survey was carried out approximately 3 years after the most recent mass distribution campaign. At each household, study staff documented reported LLIN use and source among children 2 to 10 years of age and performed a malaria rapid diagnostic test. Elevation and distance to the nearest health facility was estimated for each household. Associations between parasite prevalence and LLIN use were estimated from log binomial regression models with elevation and distance to clinic being the primary variables of interest. RESULTS: Overall, 6.8% (148 of 2170) of children age 2-10 years of age had a positive RDT result, yielding a weighted estimate of 5.8% (95% confidence interval [CI] 5.4-6.2%). There was substantial variability in the positivity rates among villages, with the highest elevation villages having lower prevalence than lowest-elevation villages (p < .001). Only 64.7% (95% CI 64.0-65.5%) of children were reported to have slept under a LLIN the previous night. Compared to those living < 1 km from a health centre, households at ≥ 2 km were less likely to report the child sleeping under a LLIN (RR 0.86, 95% CI 0.83-0.89, p < .001). Households located farther from a health centre received a higher proportion of LLINs from government distributions compared to households living closer to health centres. CONCLUSIONS: LLIN use and sourcing was correlated with household elevation and estimated distance to the nearest health facility. The findings suggest that current facility-based distribution strategies are limited in their reach. More frequent mass distribution campaigns and complementary approaches are likely required to maintain universal LLIN coverage and high rates of use among children in rural Uganda.

BACKGROUND: Measles outbreaks are prevalent throughout sub-Saharan Africa despite the preventive measures like vaccination that target under five-year-old children and health systems strengthening efforts like prioritizing the supply chain for supplies. Measles immunization coverage for Kasese district and Bugoye HC III in 2018 was 72 and 69%, respectively. This coverage has been very low and always marked red in the Red categorization (below the national target/poor performing) on the national league table indicators. The aim of this study was to assess the scope of the 2018-2019 measles outbreak and the associated risk factors among children aged 0-60 months in Bugoye sub-county, Kasese district, western Uganda. METHODS: We conducted a retrospective unmatched case-control study among children aged 0-60 months with measles (cases) who had either a clinical presentation or a laboratory confirmation (IgM positivity) presenting at Bugoye Health Centre III (BHC) or in the surrounding communities between December 2018 and October 2019.. Caregivers of the controls (whose children did not have measles) were selected at the time of data collection in July 2020. A modified CDC case investigation form was used in data collection. Quantitative data was collected and analyzed using Microsoft excel and STATA version 13. The children's immunization cards and health registers at BHC were reviewed to ascertain the immunization status of the children before the outbreak. RESULTS: An extended measles outbreak occurred in Bugoye, Uganda occured between December 2018 and October 2019. All 34 facility-based measles cases were documented to have had maculopapular rash, conjunctivitis, and cough. Also, the majority had fever (97%), coryza (94.1%), lymphadenopathy (76.5%), arthralgias (73.5%) and Koplik Spots (91.2%) as documented in the clinical registers. Similar symptoms were reported among 36 community-based cases. Getting infected even after immunized, low measles vaccination coverage were identified as the principal risk factors for this outbreak. CONCLUSION: Measles is still a significant problem. This study showed that this outbreak was associated with under-vaccination. Implementing a second routine dose of measles-rubella vaccine would not only increase the number of children with at least one dose but also boost the immunity of those who had the first dose.

We enrolled 250 febrile children in western Uganda to compare the results of malaria rapid diagnostic tests (RDTs) when using capillary vs venous blood. Participants were tested with 4 different RDT types. Polymerase chain reaction testing was performed as the reference standard. Sensitivity and specificity were broadly similar across RDT types and sampling method. Agreement between sample type was high, ranging from 0.95 to 0.99. When following the manufacturer's recommended interpretation, only 5 tests would have resulted in a different clinical diagnosis. These results demonstrate that malaria RDTs perform similarly when using capillary or venous blood in febrile children with Plasmodium falciparum malaria.

BACKGROUND: In some areas of Uganda, village health workers (VHW) deliver Integrated Community Case Management (iCCM) care, providing initial assessment of children under 5 years of age as well as protocol-based treatment of malaria, pneumonia, and diarrhoea for eligible patients. Little is known about community perspectives on or satisfaction with iCCM care. This study examines usage of and satisfaction with iCCM care as well as potential associations between these outcomes and time required to travel to the household's preferred health facility. METHODS: A cross-sectional household survey was administered in a rural subcounty in western Uganda during December 2016, using a stratified random sampling approach in villages where iCCM care was available. Households were eligible if the household contained one or more children under 5 years of age. RESULTS: A total of 271 households across 8 villages were included in the final sample. Of these, 39% reported that it took over an hour to reach their preferred health facility, and 73% reported walking to the health facility; 92% stated they had seen a VHW for iCCM care in the past, and 55% had seen a VHW in the month prior to the survey. Of respondents whose households had sought iCCM care, 60% rated their overall experience as "very good" or "excellent," 97% stated they would seek iCCM care in the future, and 92% stated they were "confident" or "very confident" in the VHW's overall abilities. Longer travel time to the household's preferred health facility did not appear to be associated with higher propensity to seek iCCM care or higher overall satisfaction with iCCM care. CONCLUSIONS: In this setting, community usage of and satisfaction with iCCM care for malaria, pneumonia, and diarrhoea appears high overall. Ease of access to facility-based care did not appear to impact the choice to access iCCM care or satisfaction with iCCM care.
