April 16, 2026- As of April 10, 2026, the amount of acute respiratory illness causing people to seek health care is “very low”. The Centers for Disease Control and Prevention (CDC) said in an update that COVID-19 activity is low in most areas of the country. Seasonal influenza activity continues to decrease in most areas of the country, and influenza A activity is low across all regions while trends in influenza B activity vary by region, per the CDC. RSV activity started later than expected in most regions of the United States, though illness is not more severe compared with recent seasons. This unusual timing means higher levels of RSV activity may continue into April in many regions.
