The late-spring respiratory virus picture is calmer nationally, according to the latest CDC update.
CDC reported on May 22 that acute respiratory illness causing people to seek health care was very low. The agency also said COVID-19, RSV and seasonal influenza activity was low in most areas.
For families, schools, workplaces and older adults, that is a useful snapshot after the heavier illness months of fall and winter. It does not mean there is no risk. It means the national indicators CDC tracks are showing a quieter period right now.
What CDC Is Seeing
CDC said wastewater activity levels for COVID-19, RSV and influenza A were very low nationally. Wastewater data is one way public health officials track virus activity in communities, alongside health care visits and other surveillance systems.
The agency continues to monitor respiratory illness activity through national surveillance systems. That matters because national levels can stay low while smaller local outbreaks still appear.
The CDC's assessment indicates that the highest combined peak hospitalizations for COVID-19, flu, and RSV occurred during the week ending January 3, 2026, which was consistent with its pre-season outlook. In contrast, the current picture is less a declaration that respiratory viruses have disappeared than a snapshot showing that national pressure on clinics and hospitals is far lower than during the winter peak.
What Remains Unclear
It is not yet clear whether activity will stay low into the summer travel season. It is also unclear whether localized outbreaks will develop even while national levels remain low, or how fall respiratory virus recommendations may change later in the year.
Readers looking for personal health guidance should follow local public health officials and their medical providers if conditions change. The practical takeaway is simple: nationally, CDC data points to a calmer late-spring respiratory illness period, but public health monitoring is still continuing.
CDC's recent data indicates that while the overall respiratory illness activity is low, it is important to remember that certain groups, such as older adults, infants, and immunocompromised individuals, may still face serious risks from respiratory infections. Additionally, RSV started later than usual in many parts of the country, which could lead to some areas experiencing elevated RSV activity into May, even as national indicators remain calm.
Furthermore, it is worth noting that the CDC's recent-week figures are preliminary and may change as delayed reports arrive. This ongoing monitoring is essential to ensure that public health responses can adapt to any emerging trends.
