CDC issues warning RSV is on the rise in young children in Southeastern US

The Centers for Disease Control and Prevention warned this week that cases of respiratory syncytial virus, or RSV, are rising among young children in some parts of the Southeastern United States.

Traditionally, RSV season begins in the fall and continues through the winter, similar to the flu and other respiratory viruses. However, RSV infections this time of year are much higher than usual, in Florida and Georgia, particularly.

Over the past four weeks, the three-week average of PCR test positivity for RSV in Florida has been above 5%, which exceeds the threshold of 3% typically seen at the start of the RSV season, the CDC said in a heath advisory.
