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.

COVID-19 cases increased in some areas of the country over the summer, which could shift the timing or size of this season's wave, though hospitalizations are projected to peak at similar levels to past years. Flu remains low in the U.S., with no signs pointing to a worse season. RSV activity is very low nationwide, but last season's RSV peak came later than usual.
