The Centers for Disease Control and Prevention (CDC) is warning the American public this week about “increases” in respiratory syncytial virus (RSV) activity across “some parts of the Southeastern United States.”
In an advisory issued through its Health Alert Network, the CDC said data shows nationwide the weekly percentage of active cases identified through PCR testing has remained below the season onset threshold of 3% for two consecutive weeks.
However, the data is also showing “PCR positivity above 3.0% in Florida beginning in the week ending July 22, 2023, and the 3-week moving average of PCR positivity has been greater than 5.0% for the past 4 weeks,” according to the CDC.
