RSV Alert: Late-Season Surge Signals Extended Precautions
Respiratory syncytial virus (RSV), usually a winter respiratory bug, is sticking around longer than expected this year. Federal health data and CDC wastewater surveillance show higher positive cases than last year, with the Midwest and northern Plains reporting notably elevated activity—even as spring unfolds.
Why Public Health Is Acting
In response, RSV immunization programs have been extended through April 30, targeting those most vulnerable:
- Infants under six months
- Older adults over 65
- People with chronic respiratory or heart conditions
Getting vaccinated now can reduce severe illness, hospital visits, and complications.
Changing Patterns: RSV Isn’t Just a Winter Virus
RSV’s late-season activity is a reminder that viruses don’t always follow predictable patterns. Experts point to several possible factors:
- Behavioral shifts: More indoor gatherings, relaxed masking, and travel may prolong virus spread.
- Immunity gaps: Fewer exposures last season mean more people are susceptible.
- Environmental conditions: Mild temperatures and humidity can keep RSV circulating longer.
