Definition Atypical pneumonia refers to pneumonia caused by certain bacteria, including Legionella pneumophila , Mycoplasma pneumoniae , and Chlamydophila pneumoniae . Pneumonia is a condition in which there is an infection of the lung. Alternative Names Walking pneumonia; Chlamydophila pneumoniae; Community-acquired pneumonia - atypical Causes, incidence, and risk factors Mycoplasma pneumonia is a type of atypical pneumonia. It is caused by the bacteria M. pneumoniae . It typically affects people younger than age 40. For more information on this type of pneumonia, see: Mycoplasma pneumonia Pneumonia due to chlamydia-related bacteria occurs year round and accounts for 5 - 15% of all pneumonias. It is usually mild. Pneumonia due to Legionella is seen more often in middle-aged and older adults, smokers, and those with chronic illnesses or a weak immune system. See also: Legionnaire's disease
Pneumonia in immunodeficient patient; Pneumonia - immunocompromised host
If you have a weakened immune system and are in the hospital, you may receive daily antibiotics to prevent pneumonia.
Ask your health care provider if you should receive the influenza ("flu") and pneumococcal ("pneumonia") vaccines.
Practice good hygiene. Thoroughly wash your hands with soap and water:
After being outdoors
After changing a diaper
After doing housework
After going to the bathroom
After touching body fluids, such as mucus or blood
After using the telephone
Before handling food or eating
Keep your house clean. Stay away from crowds. Ask visitors who have a cold to wear a mask or not to visit. Do not do yard work or handle plants or flowers (they can carry germs).

In this entry, I would like to review the impact that severe infections from a common pneumonia bacterium can have on asthmatics and discuss some recent research on how this has changed immunization schedules for asthmatics.
This new research has changed recommendations from the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC), the federal agency that monitors disease outbreaks and provides evidence-based recommendations on immunization (for kids and adults). Setting aside recommendations that apply to all individuals (especially infants and young children), there are often some modifying circumstances that have to do with health status that change recommendations - if a vaccine should be administered or not, whether a booster should be given, etc. Recent research on infections caused by a common respiratory bacterium Streptococcus pneumoniae (‘pneumococcus', in common usage) has expanded the indication for immuni...
