Opportunistic Infections

People with HIV who have low CD4 count (usually below 200) can get infections (called opportunistic infections, or OIs). Many of these illnesses are serious and need to be treated by a doctor. Some can be prevented by taking drugs before you get sick.

If you've already had an OI you might need to keep taking meds even after the infection goes away. Doctors recommend doing this to help stop the OI from coming back again.
