What is Pneumonia?
- Pneumonia is an infection that inflames the air sacs in one or both lungs.
- The air sacs may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing.
- A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.
- Pneumonia can range in seriousness from mild to life-threatening.
- It is most serious for infants and young children, people older than age 65, and people with health problems or weakened immune systems.
- The germs that cause pneumonia are contagious. Both viral and bacterial pneumonia can spread to others through inhalation of airborne droplets from a sneeze or cough. One can contract fungal pneumonia from the environment. However, it doesn’t spread from person to person.
- Vaccines are available to prevent some types of pneumonia and the flu.
