Season outlook

CDC expects the 2026-2027 respiratory illness season to be much like last season. COVID-19, flu, and RSV are projected to cause about the same number of peak hospitalizations this fall and winter. CDC will update this outlook if there are changes.

Care and prevention

Respiratory illness can affect anyone, but young children, older adults, and people with chronic conditions or weakened immune systems face the highest risk. If you have symptoms like fever, cough, or shortness of breath, rest, stay hydrated and seek medical care for severe symptoms like difficulty breathing.
