The epidemiology of rape and sexual violence in the platinum mining district of Rustenburg, South Africa: Prevalence, and factors associated with sexual violence.BACKGROUND: Estimates for the prevalence of rape and other forms of sexual violence (SV) vary in South Africa. This survey aimed to provide clarity by quantifying the prevalence of SV (forced sex or sexual acts) by 1) sexual partners, and 2) non-partners, and to describe factors associated with these outcomes among women (18-49 years) living in Rustenburg Municipality. MATERIALS AND METHODS: We conducted a cluster-randomized household survey (November-December 2015). Women were asked about their experiences of SV, associated attitudes and behaviours, and access to services. Logistic regression was used to determine factors associated with partner and non-partner SV. RESULTS: Of eligible households, 83·1% (1700/2044) participated. Of 966 women invited, 836 participated (86·5%). Average age of participants was 31.6 years (95%CI: 30·9, 32·4) with 45% having completed at least secondary school, and 60% unemployed or looking for work. Lifetime prevalence of SV was 24.9% (95%CI: 21·7-28·5), reaching 9.0% (95% CI: 6·6-12·1) by age 15. Almost one third told no one of their SV experiences. Factors related to financial dependence were associated with SV by a partner. History of termination of pregnancy increased the likelihood of SV by a non-partner as an adult. Women who experienced SV in childhood or as an adult were more likely to experience SV from a different type of perpetrator than those who did not. CONCLUSIONS: We found a high prevalence of SV, including during childhood, in this setting, with limited access to care. This and the high morbidity attributed to SV calls for increased service provision.
"They don't like us….": Barriers to antiretroviral and opioid substitution therapy among homeless HIV positive people who inject drugs in Delhi: A mixed method study.Background Provision of Anti-Retroviral Therapy (ART) and Opioid Substitution Therapy (OST) are important components of the targeted intervention (TI) programme for people who inject drugs (PWID). Homeless HIV positive PWIDs in Delhi is a key population experiencing gaps in uptake of these services, especially the ART uptake which is reportedly far from 90%, UNAIDS’ 90-90-90 target to end the AIDS epidemic. Objective To assess the gaps and barriers in accessing the ART and OST services uptake among HIV positive homeless PWID in Delhi and to explore experiences and perspectives of the PWIDs and service providers. Methodology We used a convergent parallel mixed methods design which included a cross-sectional quantitative survey and a qualitative study. Two hundred thirty five homeless HIV positive PWID were interviewed and in-depth interviews were conducted with five PWIDs and nine health providers. Results While only 12% of PWIDs were on ART, 80% were availing OST services. The top individual, health system related and structural barriers for ART service access were insufficient and incorrect knowledge (63%), long waiting time (86%) and lack of family support (44%) respectively. Inconvenient timings, stringent registration requirements and negative attitude of health providers were expressed as major barriers of accessing ART services during the interviews while these were not a concern in OST services. Homelessness, poverty, stigma were common barriers for both services. Integrated, ‘single window’ service and provision of additional support like nutrition and shelter were suggested as measures to improve access by both health providers and the PWIDs themselves. Conclusion There is an urgent need for structural and health systems changes to improve access to ART and OST services. These include integrated service delivery, flexibility in timing of the centers, accelerated ART initiation, simplification of bureaucratic procedures, nutritional and social support to all homeless HIV positive PWIDs.
Urban yellow fever outbreak—Democratic Republic of the Congo, 2016: Towards more rapid case detectionBackground Between December 2015 and July 2016, a yellow fever (YF) outbreak affected urban areas of Angola and the Democratic Republic of the Congo (DRC). We described the outbreak in DRC and assessed the accuracy of the YF case definition, to facilitate early diagnosis of cases in future urban outbreaks. Methodology/Principal findings In DRC, suspected YF infection was defined as jaundice within 2 weeks after acute fever onset and was confirmed by either IgM serology or PCR for YF viral RNA. We used case investigation and hospital admission forms. Comparing clinical signs between confirmed and discarded suspected YF cases, we calculated the predictive values of each sign for confirmed YF and the diagnostic accuracy of several suspected YF case definitions. Fifty seven of 78 (73%) confirmed cases had travelled from Angola: 88% (50/57) men; median age 31 years (IQR 25–37). 15 (19%) confirmed cases were infected locally in urban settings in DRC. Median time from symptom onset to healthcare consultation was 7 days (IQR 6–9), to appearance of jaundice 8 days (IQR 7–11), to sample collection 9 days (IQR 7–14), and to hospitalization 17 days (IQR 11–26). A case definition including fever or jaundice, combined with myalgia or a negative malaria test, yielded an improved sensitivity (100%) and specificity (57%). Conclusions/Significance As jaundice appeared late, the majority of cases were diagnosed too late for supportive care and prompt vector control. In areas with known local YF transmission, a suspected case definition without jaundice as essential criterion could facilitate earlier YF diagnosis, care and control.
