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.
“Knock Knock Knock” is a catchy and up-tempo song, with sunny Afro-jazz beats and a hard-to-forget jingle. More than a hit song on the airwaves of Zimbabwe, it is also an essential tool for public health promotion. (Watch the video, below.)
Before the PHIA survey teams begin to knock on household doors, community workers visit selected communities, known as enumeration areas, to help community leaders and members understand some of the sensitivities that surround HIV and to strengthen support for the survey.
