The risk of pneumonia in the elderly is much greater than normal: 1. The elderly are a population with lower resistance and are prone to bacterial or viral infections. 2. The elderly have a poor cough reflex and are prone to pneumonia if they have a cold or bronchitis, etc. 3. The elderly recover more slowly than normal from pneumonia because of their poor health and are also prone to other complications. Therefore, elderly people suffering from pneumonia should pay attention to it and be treated actively. The mortality rate of pneumonia in the elderly is higher than the normal population, so it is best to hospitalize the elderly once they are considered to have pneumonia.
