HIV: Preventing Infections - Topic Overview

Medicines and vaccines are used to prevent infections and certain diseases (opportunistic infections) that are more common in people with HIV.

  • Primary prevention means preventing illness before it occurs. Immunizations (vaccines) are one kind of primary prevention. Medicines that kill or control the organisms that cause infections are another type of primary prevention.
  • Secondary prevention means preventing a disease that a person has already had from coming back. This is usually done with medicines that slow or prevent the growth of the organisms that cause infections.

Generally, infection with HIV doesn't make people sick, except for the flu-like illness that may develop shortly after they become infected. Most people who are infected with HIV get sick because their immune systems become weak and cannot fight off other infections. So preventing opportunistic infections is an important part of treatment for HIV.

Lipodystrophy and HIV

Lipodystrophy is a problem with the way the body produces, uses, and stores fat. It is also called fat redistribution. Since the widespread use of antiretroviral therapy began, the numbers of HIV-positive people with lipodystrophy has increased. Today, lipodystrophy occurs in 30% to 50% of people who are infected with HIV (human immunodeficiency virus).

If you have been diagnosed with HIV infection, make sure that you and your partner are up to date on the following immunizations:

Work with your doctors to decide which medicines to use, based on:

  • The type of infection that is present or likely to develop.
  • Which other medicines you are already taking and the possibility that one medicine might make another less effective (negative interaction).
  • The side effects of the medicines.
