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

Sub-Saharan 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 global health center, is leading the charge to shed light on those affected by HIV to improve access to treatment and prevention.

ICAP, with its transformational track record in community health, is working shoulder-to-shoulder with 14 countries hardest hit by the HIV epidemic to conduct the Population-based HIV Impact Assessment (PHIA) Project, funded by the US President's Emergency Plan for AIDS Relief (PEPFAR) through the US Centers for Disease Control and Prevention (CDC).

The PHIA Project has sent more than 4,000 in-country staff to conduct door-to-door, household-based HIV counseling and testing. They are assembling millions of data points in sub-Saharan Africa and Haiti for officials to identify and deploy resources to tailor treatment and prevention. Since 2015, the PHIA Project has completed 13 national surveys, conducted over 170,000 household interviews, and tested over 370,000 adults and children.

A major goal for the PHIA Project is to provide data that will help nations reach the UNAIDS 90-90-90 targets for global epidemic control. These targets aim to have 90 percent of all people living with HIV knowing their status; 90 percent of those diagnosed with HIV on treatment; and 90 percent of those on treatment having effectively suppressed viral loads. 

“The countries need this information in order to fine-tune their response in a time of constrained resources," said Wafaa El-Sadr, University Professor and founding director of ICAP. Learn more.
