Pneumonia - weakened immune system

  • Alternative Names

    Pneumonia in immunodeficient patient; Pneumonia - immunocompromised host


    If you have a weakened immune system and are in the hospital, you may receive daily antibiotics to prevent pneumonia.

    Ask your health care provider if you should receive the influenza ("flu") and pneumococcal ("pneumonia") vaccines.

    Practice good hygiene. Thoroughly wash your hands with soap and water:

    • After being outdoors
    • After changing a diaper
    • After doing housework
    • After going to the bathroom
    • After touching body fluids, such as mucus or blood
    • After using the telephone
    • Before handling food or eating

    Keep your house clean. Stay away from crowds. Ask visitors who have a cold to wear a mask or not to visit. Do not do yard work or handle plants or flowers (they can carry germs).
