A person who has HIV has difficulty fighting off other infections. You can help protect the person from infections.

• Avoid close contact with people who have contagious illnesses until their symptoms have disappeared. This includes illnesses such as colds, the flu, or stomach flu.
• If you have a cold or flu, wear a surgical-type mask and wash your hands before approaching or touching the person with HIV.
• Get an annual flu shot to reduce the chance of getting the flu and infecting others.
• If you have skin infections such as boils, cold sores, fever blisters (herpes simplex), or shingles (herpes zoster), avoid close contact with the person who has HIV.
• Ask your doctor whether you should have any boosters or shots for measles, mumps, or rubella, because these shots may not have been available when you were a child.
• Get the special form of polio shot known as "Salk" or "inactivated virus" vaccine if you need a polio shot. Do not use the oral "Sabin" form of the vaccine.
• Contact the doctor of the person who has HIV within 24 hours if the person has not had:
  • A measles immunization and he or she is exposed to measles. A medicine is available that, if given promptly, may help prevent measles.
  • Chickenpox and he or she is exposed to chickenpox or shingles. Chickenpox can make a person with HIV very sick. For more information, see the topic Chickenpox (Varicella).
• Learn how to handle food properly. The care and handling of food requires some special considerations.
• Avoid having a person who has HIV clean pet litter or pet living areas, such as cages and tanks.
