How Long Is Pneumonia Contagious?

How long is bacterial pnuemonia contagious? Thanks for any answers.


Hi there, Caroline --

How long a person with bacterial pneumonia is contagious to others depends on the type of treatment he or she gets for the pneumonia. According to experts, untreated bacterial pneumonia generally is contagious for several days to a week, depending on the treatment. If the person with pneumonia is on antibiotics, however, the pneumonia typically stops being contagious after a day of treatment with the medications.
