Children and infants
Children are more likely to get the flu because their immune systems are not fully developed.
Pregnant women are can be more prone to severe illness from flu because of changes to their immune system during pregnancy.
Human immune systems weaken with age, making adults 65 and older more susceptible to the flu.
People with disabilities
Not all disabled people are at higher risk for getting the flu. Those who are more susceptible are those who have limited mobility, those who can’t limit their contact with others who may be infected, and those who have trouble understanding or practicing preventive measures.
People with health conditions
Certain health conditions can either increase your risk of getting the flu due to a weakened immune system, or make you more at risk for complications related to the flu. As such, special steps should be considered for people suffering from arthritis, asthma, cancer, diabetes, heart disease or HIV/AIDS.
Visit flu.gov for precautions and treatment advice for people who belong to these higher-risk groups.
