pneumonia itself is not contagious. in other words exposure to someone with pneumonia will not necessarily cause pneumonia in you. but that doesn't mean you can't get sick. pneumonia can be caused by hundreds of different viruses bacteria and even fungi. it is the organism/pathogen that may be contagious not the end-disease caused by that pathogen like pneumonia.
is an pneumonia contagious? if it is how long is the incubation period? . my roommate had an pneumonia a week ago and now me and my other roommate are both getting sick. we both have a cough and i have weezing when i breathe deep and a mild fever. i also have a headache but i was wondering if we could have gotten something from our roommate.
