Collecting fingerstick blood to perform HIV rapid test screening at a Prevention of Mother-to-Child Transmission Demonstration Project site in Battambang province. CDC GAP, the National Maternal and Child Health Center, and the National Center for HIV/AIDS, Dermatology, and STDs (NCHADS) are collaborating on a project to demonstrate feasibility of screening pregnant women and their partners for HIV at health centers as a routine component of antenatal care. Currently, NCHADS requires that all HIV testing be performed at designated voluntary confidential counseling and testing (VCCT) sites. Because most antenatal care clinics are not collocated with VCCT sites, pregnant women ordinarily need to travel to another site for HIV testing. This demonstration project will help determine whether HIV screening can be performed safely and accurately in health centers and whether same-site screening will improve HIV testing rates among pregnant women in Cambodia.
