Who is at high risk of getting very sick from respiratory illnesses?

Generally, severe cases are more likely to occur in the following people:

• Older adults (the older you are, the higher your risk for severe illness)
• People of any age with underlying medical conditions
• Infants and young children less than 5 years old 
• Pregnant women

It is important to note that serious illness can also occur in young, healthy adults. If you have questions about your risk, talk to your healthcare provider.
