Preventing mother-to-child HIV transmission: the first year of Thailand's national program.

CONTEXT: Each year in Thailand, about 10,000 children are born at risk for mother-to-child human immunodeficiency virus (HIV) transmission. In 2000, Thailand implemented a national program to prevent mother-to-child HIV transmission.
OBJECTIVE: To describe the results of implementation of the program.
DESIGN: Monthly collection of summary data from hospitals.
SETTING: Public health hospitals (n = 822) in all 12 regions of Thailand, representing 75 provinces, excluding Bangkok. PARTICIPANTS: Women giving birth from October 2000 through September 2001, including HIV-seropositive women and their neonates. MAIN OUTCOME MEASURES: Percentages of women giving birth who were tested for HIV, HIV-seropositive women giving birth who received antenatal prophylactic antiretroviral drugs, and HIV-exposed neonates who received prophylactic antiretroviral drugs and infant formula.
RESULTS: Among 573,655 women (range, 27,344-77,806 by region) giving birth, 554,912 (96.7%) received antenatal care (range, 91.9%-98.8% by region). Of 554,912 women giving birth who had antenatal care, 517,488 (93.3%) were tested for HIV (range, 87.7%-99.4% by region) before giving birth; of 18,743 women giving birth who did not have antenatal care, 13,314 (71.0%) were tested for HIV (range, 21.7%-92.9% by region). Of 6646 HIV-seropositive women giving birth, 4659 (70.1%) received prophylactic antiretroviral drugs before delivery (range, 55.3%-81.2% by region). Of 6475 neonates of HIV-seropositive women, 5741 (88.7%) received prophylactic antiretroviral drugs (range, 67.4%-96.9% by region) and 5386 (83.2%) received infant formula (range, 65.3%-100% by region).
CONCLUSIONS: Major program components of Thailand's national program for preventing mother-to-child HIV transmission were implemented. Thailand's experience may encourage other developing countries to implement or expand similar national programs.
