I had a very bad case of septic pneumonia 6 mos ago. it was the first time i've ever had it. will i be more likely to get pneumonia again?

Pneumonia: Perhaps. Do not smoke, or use drugs. Eat a healthy diet. Avoid second hand smoke and any chemical lung irritants. Exercise in clean air areas (not in traffic areas). If you have asthma, see an allergist.

Probably not: You have same risk as any other person. But if you had MRSA pneumonia then you may have a bit high chance of getting pneumonia. Risk gets high if you smoke.
