A lung illness known as pneumonia is brought on by bacteria, viruses, or fungus. It is a dangerous illness when pus and other liquids fill the air sacs. One or more lobes (sections) of the lungs are affected by lobular pneumonia. Patches of both lungs are affected by bronchial pneumonia, sometimes called bronchopneumonia.
Pneumonia has more than 30 distinct causes, which are categorised by the cause. The most common kinds of pneumonia include:
Lung infection brought on by certain bacteria is called bacterial pneumonia. Streptococcus (pneumococcus) is the most typical, however other bacteria might also be the culprit. These bacteria can dwell in your throat unharmed if you’re young and generally healthy. Yet, if for any reason your immune system becomes weakened, the germs may enter your lungs. As a result, the air sacs in your lungs get infected and swollen. As a result of the fluid buildup, pneumonia develops.
A viral infection of the lungs is known as viral pneumonia. The flu is the most frequent cause, although other viruses including the common cold and others can also cause viral pneumonia. The higher region of your respiratory system is where these unpleasant viruses typically stay. But, the problem arises when they enter your lungs. Your lungs’ air sacs then become diseased, swollen, and filled with fluid.
This type has somewhat different symptoms and physical signs and is referred to as atypical pneumonia. It is caused by the bacterium Mycoplasma pneumoniae. It generally causes a mild, widespread pneumonia that affects all age groups.
There are other less common pneumonias that may be caused by other infections including fungi. Anyone can get pneumonia. However, the following groups are at the highest risk:
– Adults ages 65 and older
– Children younger than age 2
– People with certain medical conditions
– People that smoke
