Microbicide researchers are committed to providing a high standard of HIV prevention and care to all study participants. Participants are provided with counseling, condoms, and sometimes additional services to help them prevent HIV infection during a trial. Researchers also make agreements with local hospitals and other health facilities to ensure that participants who become infected with HIV during the trial will receive appropriate health care. Men and women who are found to be HIV-positive during screening are also referred to high-quality affordable services to meet their physical and psychological needs.
