The Call to Action Project was launched in 1999 by the Elizabeth Glaser Pediatric AIDS Foundation to increase access to and scale up prevention of mother-to-child transmission (PMTCT) services. From 2002 to 2010, with $100 million in funding from USAID, the project supported over 2,600 PMTCT sites across 14 countries. By the end of 2009, the project had provided nearly 4 million women with access to PMTCT services and showed that 97% of pregnant women received HIV counseling, 92% accepted testing, and 88% of HIV-positive women received antiretroviral prophylaxis for PMTCT.
