HIV Incidence Remains High in KwaZulu-Natal, South Africa: Evidence from Three Districts

Background: HIV prevalence and incidence among sexually active women in peri-urban areas of Ladysmith, Edendale, and Pinetown, KwaZulu-Natal, South Africa, were assessed between October 2007 and February 2010 in preparation for vaginal microbicide trials. Methodology/Principal Findings: Sexually active women 18-35 years, not known to be HIV-positive or pregnant were tested cross-sectionally to determine HIV and pregnancy prevalence (798 in Ladysmith, 1,084 in Edendale, and 891 in Pinetown). Out of these, approximately 300 confirmed non-pregnant, HIV-negative women were subsequently enrolled at each clinical research center (CRC) in a 12-month cohort study with quarterly study visits. Women in the cohort studies were required to use a condom plus a hormonal contraceptive method. HIV prevalence rates in the baseline cross-sectional surveys were high: 42% in Ladysmith, 46% in Edendale and 41% in Pinetown. Around 90% of study participants at each CRC reported one sex partner in the last 3 months, but only 14-30% stated that they were sure that none of their sex partners were HIV-positive. HIV incidence rates based on seroconversions over 12 months were 14.8/100 person-years (PY) (95% CI 9.7, 19.8) in Ladysmith, 6.3/100 PY (95% CI 3.2, 9.4) in Edendale, and 7.2/100 PY (95% CI 3.7, 10.7) in Pinetown. The 12-month pregnancy incidence rates (in the context of high reported contraceptive use) were: 5.7/100 PY (95% CI 2.6, 8.7) in Ladysmith, 3.1/100 PY (95% CI 0.9, 5.2) in Edendale and 6.3/100 PY (95% CI 3.0, 9.6) in Pinetown. Conclusions/Significance: HIV prevalence and incidence remain high in peri-urban areas of KwaZulu-Nata

Whoonga: Potential Recreational Use of HIV Antiretroviral Medication in South Africa

Whoonga is a drug cocktail in South Africa rumored to contain illicit drugs and HIV antiretroviral (ARV) medication. Although its use may adversely impact adherence to HIV treatment and may have the potential to generate ARV resistance, there is a paucity of research characterizing whoonga. We learned of whoonga during semi-structured interviews about substance abuse and HIV risk at “club-events” known as inkwaris in an urban township of Durban, South Africa. Whoonga was an emerging theme spontaneously identified as a problem for the community by 17 out of 22 informants. Perceptions of whoonga suggest that it is highly addictive, contains ARVs (notably efavirenz), is used by individuals as young as 14, and poses a threat to the health and safety of those who use it, including increasing the risk of HIV infection. Our informants provide preliminary evidence of the dangers of whoonga and reinforce the need for further study
