Don't ignore this lung infection
Pneumonia is an infection of one or both of the lungs. Many germs—such as bacteria, viruses and fungi—can trigger pneumonia. The disease can be particularly serious in children younger than 5 years old, older adults and people with health problems.

- High fever.

- Cough with phlegm that gets worse or doesn't improve.
