Recent PHIA News
Join us to learn what the Population-based HIV Impact Assessment (PHIA) surveys data are telling us about the evolving HIV epidemic.
Newly released findings from national HIV surveys in Zimbabwe, Malawi, and Zambia reveal extraordinary progress in confronting the HIV epidemic. These three countries in Southern Africa have been heavily affected by HIV and now there are encouraging signs that the epidemics are going in the right direction.
Preliminary results from the PHIA Project are now available for Zimbabwe, Malawi, and Zambia, and the news is excellent.
The Population-based HIV Impact Assessment (PHIA) Project, which relies on laboratory testing of blood samples as a core component, is providing answers to these questions. Led by ICAP at Columbia University, the PHIA surveys will assess the HIV epidemic in 13 select countries located primarily in sub-Saharan Africa. Fieldwork is nearly complete in three countries, with ten more national surveys to follow over the next two to three years.
