The research by the Africa Centre for Health and Population Studies marks the first time that the positive impact of antiretroviral therapy on infection rates has been proven for a community, said the UN agency.
“These findings are extremely important,” said UNAIDS programme division’s deputy executive director Paul De Lay.
“UNAIDS encourages all countries and communities to achieve high coverage of antiretroviral therapy, both for the benefit of people living with HIV and for the communities in which they live,” said De Lay.
The research on data collected from eastern South Africa’s KwaZulu-Natal province found that in areas where antiretroviral therapy uptake is above 30 per cent, uninfected people are 38 per cent less likely to acquire the human immunodeficiency virus.
“It is the first time that we have been able to show such results in a population setting -- an important finding which will help guide the AIDS response,” said Frank Tanser from the research centre in the University of KwaZulu-Natal. — Reuters
