O'nyong-nyong (ONN) fever, caused by infection with a mosquito-borne central African alphavirus, is an acute, nonfatal illness characterized by polyarthralgia. During 1996-1997, south-central Uganda experienced the second ONN fever epidemic ever recognized. Among 391 persons interviewed and sampled, 40 cases of confirmed and 21 of presumptive, well-characterized acute, recent, or previous ONN fever were identified through active case-finding efforts or during a household serosurvey and by the application of clinical and laboratory criteria. Among confirmed cases, the knees and ankles were the joints most commonly affected. The median duration of arthralgia was 6 days (range, 2-21 days) and of immobilization was 4 days (range, 1-14 days). In the majority, generalized skin rash was reported, and nearly half had lymphadenopathy, mainly of the cervical region. Viremia was documented in 16 cases, primarily during the first 3 days of illness, and in some of these, body temperature was normal. During this epidemic, the combination of fever, arthralgia, and lymphadenopathy had a specificity of 83% and a sensitivity of 61% in the identification of cases of ONN fever and thus could be useful for surveillance purposes.

O'nyong-nyong (ONN) fever, an acute, nonfatal illness characterized by polyarthralgia, is caused by infection with a mosquito-borne central African alphavirus. During 1996-1997, south-central Uganda experienced the second ONN fever epidemic ever recognized. During January and early February 1997, active case-finding and a household cluster serosurvey were conducted in two affected and two comparison areas. A confirmed case was defined as an acute febrile illness with polyarthralgia occurring within the previous 9 months plus serologic confirmation or isolation of ONN virus from blood. In affected (n=129) and comparison (n=115) areas, the estimated infection rates were 45% and 3%, respectively, and the estimated attack rates were 29% and 0%, respectively, for an apparent:inapparent infection ratio of nearly 2 in affected areas. In villages sampled near Lake Kijanebalola, Rakai District, the estimated infection and attack rates were 68% and 41%, respectively, and 55% of sampled households had >/=1 case of ONN fever. In conclusion, this epidemic was focused near lakes and swamps, where it was associated with high infection and attack rates.

All health facilities, public and private, in Liberia, West Africa. To determine access to antenatal care (ANC), deliveries and their outcomes before, during and after the 2014-2015 Ebola outbreak. This was a descriptive cross-sectional study. During the Ebola outbreak in Liberia, overall monthly reporting from health facilities plunged by 43%. Access to ANC declined by 50% and reported deliveries fell by one third during the outbreak. Reported deliveries by skilled attendants and Caesarian section declined by respectively 32% and 60%. Facility-based deliveries dropped by 35% and reported community deliveries fell by 47%. There was an overall decline in reported stillbirths, maternal and neonatal deaths, by 50%, during the outbreak. ANC, reported deliveries and related outcomes returned to pre-outbreak levels within one year following the outbreak. The Liberian health system was considerably weakened during the Ebola outbreak and had difficulties providing basic maternal health services. In the light of the major reporting gaps during the Ebola period, and the reduced use of health facilities for maternal care, these findings highlight the need for measures to avoid such disruptions during future outbreaks.

IntroductionCommunity health volunteers (CHVs) play an integral role in primary healthcare. Several countries rely on CHV programs as a major element in improving access to care and attaining universal health coverage. However, their performance has been heterogeneous and at times context-specific, and influenced by multiple factors. We describe the socio-demographic and workplace characteristics affecting CHVs’ performance in a public health program in rural western Uganda.MethodsThis was a cross-sectional study based on routine program data of CHVs serving the catchment of Bwindi Community Hospital, Kanungu District, South Western Uganda, in 2014 and 2015. Information was collected on individual socio-demographic and workplace characteristics of the CHVs. To assess their work output, we defined study-specific targets in terms of attendance at monthly CHVs’ meetings with community health nurses, households followed-up and reported, children screened for malnutrition, immunization coverage, and health facility deliveries. Frequencies and proportions are reported for characteristics and outputs and odds ratios for study-specific factors associated with overall performance.ResultsOf the 508 CHVs, 65% were women, 48% were aged 35 years and below, and 37% took care of more than the recommended 20–30 households. Seventy-eight percent of the CHVs had ≥80% of pregnant women under their care delivering in health units, 71% had ≥95% of the children on schedule for routine immunization, while 27% screened ≥75% of the children under 5 years for malnutrition. More refresher trainings was associated with better overall performance [adjusted odds ratio (aOR): 12.2, 95% confidence interval (CI): 1.6–93.6, P = 0.02] while overseeing more than the recommended 20–30 households reduced overall performance (aOR: 0.6, 95% CI: 0.4–0.9, P = 0.02).ConclusionBeing in-charge of more than the recommended households was associated with reduced performance of CHVs, while more refresher trainings were associated with improved performance. If the CHVs are to remain a strategic pillar in universal health coverage, it is imperative to address those factors known to impact on their performance.

All health facilities providing routine immunisation services in Liberia. To compare the number of routine facility-based and outreach immunisations and measles cases before, during and after the Ebola outbreak. A descriptive cross-sectional study. Immunisation coverage for fully immunised children before the Ebola outbreak was 73%. Immunisation coverage for all antigens declined by half compared to baseline during the outbreak. These findings were similar in facility-based and outreach immunisations. During the outbreak, the proportion of fully immunised children dropped by respectively 58%, 33% and 39% in the most, moderately and least Ebola-affected counties. Immunisation rate of recovery in the post-Ebola period was respectively 82%, 21% and 9% in the most, moderately and least affected counties compared to the Ebola-outbreak period. Outreach immunisation recovered slowly compared to facility-based immunisation. The mean number of measles cases reported per month was 12 pre-Ebola, 16 Ebola and 60 post-Ebola. This study provides insights into the possible impact of an Ebola outbreak on countrywide immunisation. The outbreak weakened a struggling national immunisation programme, and post-outbreak recovery took significant time, which likely contributed to the measles epidemic. Recommendations for the improvement of immunisation services that could limit further preventable epidemics in Liberia and similar contexts at risk for Ebola are provided.
