Who is considered high risk?

Like COVID-19, anybody can get the flu. But some people are at a higher risk of developing complications than others.1,2

For the flu specifically, these people include:2–4


People with chronic medical conditions may also be at risk of developing complications from the flu.2

  • Neurological and neurodevelopmental conditions
  • Chronic heart or lung disease
  • Asthma
  • Long-term aspirin therapy (younger than 19 years of age)
  • Extreme obesity (body mass index [BMI] of 40 or more)
  • Blood / endocrine / kidney / liver / metabolic disorders
  • Weakened immune system due to disease or medication
