Study Of HIV Infection Rates Lower In High Treatment Areas

Peoria, IL (PressExposure) March 08, 2012 -- Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV).The illness interferes with the immune system, making people with AIDS much more likely to get infections, including opportunistic infections and tumors that do not affect people with working immune systems. This susceptibility gets worse as the disease continues.

HIV is transmitted in many ways, such as: vaginal, oral or anal sex; blood transfusion; contaminated hypodermic needles; and exchange between mother and baby during pregnancy, childbirth, and breastfeeding. It can be transmitted by any contact of a mucous membrane or the bloodstream with a bodily fluid that has the virus in it, such as the blood, semen, vaginal fluid, preseminal fluid, or breast milk from an infected person.

A new study shows that people living in areas where uptake of HIV treatment is high are less likely to acquire the virus than in places where few are given care, UNAIDS said Thursday.

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 percent, uninfected people are 38 percent 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.
