Pneumonia: There are so many types of pneumonia and ways that people get pneumonia that a one size fits all answer here is impossible. Yes, it can be contagious in certain circumstances and in certain individuals. But, in most cases it is not passed on easily in normal social settings.
Dr. Stephen Scholand
Infectious Disease 23 years experience
Most forms - yes.: There are some bacteria and viruses that specialize in causing pneumonia. These are definitely contagious. For older folks or folks that have immune problems/chronic diseases, these patients can get protection with a 'pneumonia shot'. Then there are 'flu' shots that I'm sure you've heard of. Some types of pneumonia don't spread like 'choking on your vomit' - we call that aspiration pneumonia.

A 27-year-old female asked:

Is pneumonia or bronchitis contagious?

2 doctor answers3 doctors weighed in
Dr. Basil Harris
Emergency Medicine 23 years experience
Mostly YES: Pneumonia or acute bronchitis are respiratory illnesses caused by viruses or bacteria. Typically these are spread by droplets when an infected individual coughs. It is flu season! limit the spread by staying home from work when you are sick and covering your cough. But some conditions, like chronic bronchitis, are lung problems that can flare or get worse without infection and aren't contagious.

A 38-year-old female asked:

Is MRSA pneumonia contagious?

2 doctor answers3 doctors weighed in
Dr. David Dinhofer
Radiology 41 years experience
Yes: Although not that simple. When someone has MRSA pneumonia, the droplets that come out when they cough can contain MRSA. MRSA is not airborne except in droplets and it doesn't survive long outside. It is acquired by touching a person or object that has live MRSA bacteria on it. Hand washing is best for prevention. the patient with MRSA pneumonia should be isolated and wear a mask.
