Unfortunately, many die because they believe pneumonia is not a big deal. Pneumonia is an infection of the lung. And it can vary from a mild case to a life-threatening or fatal disease. CAP may be caused by either a virus or bacteria. The most common forms are due to streptococcus pneumoniae and hemophilus influenzae.
Pneumonia is a challenging infection for patients.
Some people simply feel ill, have a cough and fever. Others complain of fatigue, chest or back pain. Still others notice a heavy feeling in the chest or difficulty breathing. People may be confused by the doctor's remarks. Pneumonia also presents challenges for family physicians.
