Seasonal influenza activity remains low across the United States, but it has started to increase as the country enters the fall and winter respiratory illness season.
The Centers for Disease Control and Prevention says COVID 19 activity remains elevated in some regions but is declining nationally, while RSV activity remains very low in most areas.
The CDC currently expects combined hospitalizations from flu, COVID 19 and RSV during the 2026 to 2027 season to peak at roughly similar levels to last winter.
Officials caution that respiratory virus seasons can change quickly and vary significantly between regions.
Young children, older adults and people with weakened immune systems or chronic medical conditions face a higher risk of serious illness.
The CDC continues to recommend basic prevention measures, including regular handwashing, covering coughs, staying home when seriously ill and improving ventilation when possible.
It also recommends annual influenza vaccination for most people aged six months and older.
Health officials will continue updating forecasts as more data becomes available during winter.
