High-risk groups for severe influenza include people who are more likely to develop complications or require hospitalization. This clearly includes elderly adults, pregnant people, and those with chronic medical conditions such as heart, lung, kidney, or immune-system problems. These groups are specifically prioritized for antiviral treatment because starting therapy early can significantly reduce the risk of severe illness and death in them.

Infants under 1 year are also at high risk and often prioritized for treatment, but stating that only this group is high risk ignores other major risks, like age and chronic illnesses. That broader set of high-risk categories is why listing elderly adults, pregnant people, and those with chronic conditions best captures who should be prioritized for antiviral therapy.
