Pneumonia is the filling of the air sacs in the lung with an inflamed fluid. Pneumonia, which is caused by viruses, bacteria and rarely fungal infections reaching the lungs, is contagious. Pneumonia is one of the leading causes of death in children aged 0-4 years in our country.
The disease can be seen at any age, but pneumonia can be very dangerous in children under the age of 2, in people with a very weak immune system, and in people over the age of 65. Pneumonia is more common in children with heart disease or previous lung disease, and in premature births.

As pneumonia symptoms are often confused with upper respiratory infection, coronavirus symptoms and flu, patients may apply to the doctor late. This leads to progression of the disease and delays in treatment. About 7% of all deaths in the world are thought to be due to pneumonia.
