Exposure to HIV in one St. Louis area high school prompts health officials to meet with parents and students.
On Wednesday doctors from the health department came to answer questions and urge students to get tested.
Health officials said routine testing showed that several students at Normandy High School could have been exposed to the virus.
HIV is a chronic medical condition that can be treated but not yet cured. People infected with HIV almost always develop AIDS.
During the meeting, doctors encouraged parents to talk to their students about ways the virus can be spread and prevented.
