|Walking pneumonia vs regular pneumonia|
Viruses or a bacteria most often cause pneumonia. All are more or less contagious. However, just because somebody you know or work with has pneumonia doesn't mean you need to see a doctor. If you do get symptoms, by all means seek care. Since some kinds tend to spread in workplaces, it'd be appropriate for you to tell your health care provider at that time if you think you've been exposed.
Tuberculosis (TB) is a kind of pneumonia caused by a particular organism. It's pretty contagious, and if you've had close contact with a person with active TB, you should be checked. This is usually done with a skin test. If your skin test "converts" from negative to positive, your doctor should talk to you about whether it's appropriate for you to be treated with prophylactic antibiotics against TB.
