1 lung is the usual: The most common forms of pneumonia in an 18 year old usually only affect one lung and most of the time, recovery is complete. Yes, pneumonia is contagious, but usually not as contagious as a cold or the flu. It depends upon type of bacteria or virus that is causing the pneumonia, but it most cases you should feel significantly better within 24-36 hours after you start the proper treatment.
