International staff: 6 National staff: 24 MSF worked in El Salvador from 1983 to 1992, during the civil war, and returned at the end of 1998, in the aftermath of Hurricane Mitch.

MSF has finished its medical programs in El Salvador, after four and a half years of work in the country. Over the last several years, MSF has focused on HIV/AIDS. One project promoted safe sex and HIV/AIDS prevention to commercial sex workers in four departments, including the capital San Salvador. About 500 commercial sex workers passed through this program. In the San Salvador metropolitan area, in close cooperation with the Ministry of Health, MSF ran a program to prevent mother-to-child transmission of HIV, altogether treating nearly 300 mother-child pairs. Additionally, staff in 12 health centers and at the maternity and children's hospitals received training and information on HIV/AIDS. MSF also improved voluntary counseling and testing as part of prenatal care, and helped raise awareness at the Ministry of Health of the importance of availability and access to AIDS tests.
