If you're young and healthy, seasonal influenza usually isn't serious. Although you may feel miserable while you have it, the flu usually goes away in a week or two with no lasting effects. But high-risk children and adults may develop complications such as:
- Asthma flare-ups
- Heart problems
- Ear infections
Pneumonia is the most serious complication. For older adults and people with a chronic illness, pneumonia can be deadly.
