Is Pneumonia Contagious?

How Long Is a Person With Pneumonia Contagious?

The time that a person with pneumonia is contagious will depend on what germ is causing the infection, although scientists are not exactly sure when the contagious period starts and ends.
 
For certain viruses, the best guess is that a person becomes contagious about two to three days before developing symptoms. This period can last until the person no longer shows any symptoms. So in theory, a person with pneumonia is contagious for about two weeks, although they tend to be most contagious when symptoms are at their worst -- which is usually around day two to four.
 

What Can I Do to Limit My Chances of Getting Sick?

You can limit your chances of getting sick by practicing good prevention. This includes:
 
  • Washing your hands regularly
  • Keeping your hands away from your nose, mouth, and eyes
  • Limiting exposure to infected people
  • Not sharing glasses, eating utensils, or other items that are easily contaminated.
