Usually, uncomplicated influenza gets better with or without treatment but may cause substantial discomfort and limit activities while it lasts.

People with chronic medical conditions (including obesity), children younger than 2 years old, patients 65 years and older, and pregnant women may be at increased risk for complications.Many other diseases, including rapidly progressive bloodstream infections, may start with symptoms that resemble influenza, and may need to be considered in treatment decisions.
