Respiratory Virus RSV Prompts Extended Public Health Measures in the U.S.

Respiratory syncytial virus (RSV), often considered a typical seasonal respiratory illness, is showing an unusually prolonged pattern this year. Recent federal health data indicate that positive test results are higher than levels observed last year, even as spring progresses. Wastewater surveillance conducted by the CDC shows that approximately half of the United States is experiencing moderate circulation, with the Midwest and northern Plains reporting consistently higher activity.
