(pleuropneumonia )
Pneumonia is an infection in one or both lungs. Bacteria, viruses, and fungi cause it. The infection causes inflammation in the air sacs in your lungs, which are called alveoli. The alveoli fill with fluid or pus, making it difficult to breathe.
Pneumonia can affect anyone. But the two age groups at highest risk are: Children who are 2 years old or younger People who are age 65 or older
Take any medications as prescribed by your doctor. If your pneumonia is caused by bacteria, you will be given an antibiotic. It is important to take all the antibiotic until it is gone, even though you will probably start to feel better in a couple of days.
This 3D medical animation features an overview of the symptoms and risk factors of pneumonia. The normal anatomy and physiology of the lungs, along with the types of pathogens that cause pneumonia, common treatment options and ways to lower the risk for developing pneumonia are also provided.
Pneumonia symptoms can be mild to life-threatening. They can include:
Other symptoms can vary according to your age and general health:-
Many germs can cause pneumonia. The most common are bacteria and viruses in the air we breathe. Your body usually prevents these germs from infecting your lungs. But sometimes these germs can overpower your immune system, even if your health is generally good.
Community-acquired pneumonia is the most common type of pneumonia. It occurs outside of hospitals or other health care facilities.
People already in the hospital for something else, such as a surgery, are at a higher risk of developing septicemia. Secondary infections can occur while in the hospital. These infections are often more dangerous because the bacteria may already be resistant to antibiotics.
