Can door-to-door testing turn the tide of Africa’s AIDS epidemic?

The sub-Saharan region of Africa comprises just over 10 percent of the world’s population but 70 percent of those infected with HIV. ICAP, the Mailman School of Public Health’s HIV/AIDS center, is leading the charge to shed light on those affected by AIDS to improve treatment access.

ICAP, a global health leader with a transformational track record of improving community health, is heading the Population-based HIV Impact Assessment (PHIA) Project, funded by the US President’s Emergency Plan for AIDS Relief (PEPDFAR), which has sent more than 1,000 field workers door-to-door to provide on-site AIDS testing for African residents. They are assembling millions of data points in 13 countries for officials to identify and deploy resources to tailor treatment and prevention efforts.

One goal is to reach 90-90-90 for global targets: 90 percent of all HIV-positive people to be aware of their infection, 90 percent of those who test HIV-positive to be on treatment, and 90 percent of those on treatment to have effectively suppressed viral loads. 

“When one thinks about what needs to be done next, it’s daunting,” said Wafaa El-Sadr, University Professor and founding director of ICAP. “The countries need this information in order to fine-tune their response in a time of constrained resources.” Learn more.
