Pneumonia is an infection of the lungs that can cause mild to severe illness in people of all ages. Depending on the cause, doctors often treat pneumonia with medicine. In addition, vaccines can prevent some types of pneumonia. However, it is still the leading infectious cause of death in children younger than 5 years old worldwide. Common signs of pneumonia include cough, fever, and difficulty breathing. You can help prevent pneumonia and other respiratory infections by following good hygiene practices. These practices include washing your hands regularly and disinfecting frequently touched surfaces. Making healthy choices, like quitting smoking and managing ongoing medical conditions, can also help prevent pneumonia.
