Febrile jaundice results clinically in generalized yellow coloration of the teguments and mucous membranes due to excess plasma bilirubin, accompanied by fever. Two types are found: conjugated and unconjugated bilirubin jaundice. Jaundice is a sign in several diseases due to viruses (viral hepatitis and arbovirus), parasites (malaria) and bacteria (leptospirosis). In the Central African Republic (CAR), only yellow fever is included on the list of diseases for surveillance. The aim of this study was to identify the other pathogens that can cause febrile jaundice, for better management of patients. Between 2008 and 2010, 198 sera negative for yellow fever IgM were randomly selected from 2177 samples collected during yellow fever surveillance. Laboratory analyses targeted four groups of pathogens: hepatitis B, C, delta and E viruses; dengue, chikungunya, Zika, Crimean–Congo haemorrhagic fever, West Nile and Rift Valley arboviruses; malaria parasites; and bacteria (leptospirosis). Overall, 30.9% sera were positive for hepatitis B, 20.2% for hepatitis E, 12.3% for hepatitis C and 8.2% for malaria. The majority of positive sera (40.4%) were from people aged 16–30 years. Co-infection with at least two of these pathogens was also found. These findings suggest that a systematic investigation should be undertaken of infectious agents that cause febrile jaundice in the CAR.

Tuberculosis (TB) is endemic in the Central African Republic (CAR) with an incidence rate of 391 per 100,000 population in 2015. This study aims to analyze current epidemiological and clinical features of TB at the Hôpital de l'Amitié in the Central African Republic. We conducted an analytic retrospective study of patients hospitalized in the Department of Medicine at the Hôpital de l'Amitié from 15 April 2010 to 14 October 2011. Data were collected using a questionnaire and then analyzed with Epi info software 3.5.3. Chi-square test was used to compare proportions, using a threshold significance level of 5%. The study included 220 patients, of whom 128 were women (58.18%). The average age of patients was 35.69± 10.65 years. In 42.70% of cases, patients had no professional activity. Prevalence of tuberculosis in hospital was 10.99%. On average, 12 cases of TB were recorded each month. Most common clinical signs included: chronic cough (71.81%), fever (96.82%), alteration of the general state (91.36%) and pulmonary condensation syndrome (63.64%). The diseases most commonly associated with tuberculosis were HIV/AIDS (73.36%), malaria (48.63%) and anemia (31.81%). The mean time between symptom onset and diagnosis was 37.65 days. Mortality rate was 18.63%. TB/HIV co-infection and neuromeningeal TB were associated with a high mortality rate (p < 0.05). Tuberculosis is a common disease in Bangui and it is often associated with HIV infection. Prognosis is poor in the case of neuromeningeal involvement. Prevention and routine monitoring in HIV infected patients may contribute to reduce the extent and severity of TB.

Introduction: The retention in care of patients undergoing antiretroviral therapy (ART) is a cornerstone for preventing AIDS‐associated morbidity and mortality, as well as further transmission of HIV. Adherence to ART poses particular challenges in conflict‐affected settings like the Central African Republic (CAR). The study objective was to estimate the rate of lost‐to‐follow‐up (LTFU) and determine factors associated with LTFU among patients living with HIV under ART in CAR.Methods: A retrospective cohort analysis was conducted using data from patients being managed at 42 representative ART dispensing sites (i.e. management of ≥200 patients) in the seven health regions of CAR which started ART between January 2019 to September 2021 and followed up to December 2021. The outcome of LTFU was defined as a failure of a patient to attend a scheduled ART refill appointment for at least 90 days from the last appointment. Patients were censored at the first LTFU event.Results: A total of 6844 patients enrolled in ART care were included in the analysis, of whom 67.5% were females. The mean age (standard deviation) was 35.3 years (10.5). Forty‐two per cent (n = 2874/6844) had an LTFU event during the follow‐up period. However, 23.2% (n = 666/2874) returned to care after LTFU. Overall retention in antiretroviral care at 12 months was 64.2% (CI 63.0−65.5), which ranged from 76.1% in the capital to 48.2% in the inner country region. Risk factors related to LTFU were being male (adjusted hazard ratio [aHR] 1.33; CI 1.1−1.5), age < 25 (aHR 1.46; CI 1.1−1.9), living in regions outside the capital (aHR 1.83; CI 1.6−2.3) and undernutrition (aHR 1.13; CI 1.0−1.3).Conclusions: Retention to care in CAR is suboptimal, especially in the inner country. Our results underline the difficulties involved in retaining patients in ART in complex settings, the interplay between poor retention, social unrest, stigma, food insecurity and HIV epidemic control, and the need for tailored programming and interventions like differentiated treatment strategies and complementary food provision.

Background: The objectives of this study were to determine the association between the vulnerability factors linked to human immunodeficiency virus (HIV) and other sexually transmitted infection among the young women who sell sex (YWSS) group (15–24 years) and adult sex workers, engaged in consensual sex for money (AFSW). Methods: A cross-sectional study was conducted among AFSW involved in commercial sex transactions. Prevalence ratios (PR) analysis was carried out using log-binomial regression model. Results: The prevalence of HIV-1 was 29.4% among YWSS compared to 19.6% among female sex worker (PR = 1.43 [1.07–1.91]). Consistent condoms use last 3 months were very low at 22.3% and 41.2%, respectively (PR = 0.52 [0.37–0.74]), the low education level among YWSS versus AFSW (PR = 0.55 [0.40–0.76]); YWSS having been a victim of sexual violence in the last 12 months (PR = 2.00 [1.52–2.63]), were also more likely to be HIV positive. Conclusions: The YWSS had a high prevalence of HIV, experienced other socioeconomic vulnerabilities and remain a key population for comprehensive HIV programs. To reach all YWSS, programs need to consider many outreach programs and address the shared determinants of HIV risk.
