Influenza (Flu) in Arizona
Information for Special Populations
Most people who get influenza will have a mild illness and recover in less than two weeks, but some people will develop complications that can be very severe. Complications and severe illness are more likely in young children and people over 65 years old, or in people with certain chronic health conditions.
Additionally, people in some occupations or settings, or who live with or care for people at high risk of complications, may be at increased risk of being infected with influenza or passing it on to other people.
In general, yearly flu vaccination is the best way to protect anyone at high risk of getting the flu or flu-related complications. Additional information for specific populations is below.
