RSV Seasonality Remains Mixed Globally

The World Health Organization (WHO) reported this week respiratory syncytial virus RSV activity was generally low worldwide except in Australia and a few countries in the Region of the Americas.

And as of June 26, 2023, RSV activity increased in a few tropical and temperate South American countries.

Furthermore, in the United Kingdom, the RSV detection rate among children under five years of age remained at a low level in June 2023.

In the U.S., Florida's RSV season is longer than the rest of the country, says the U.S. Centers for Disease Control and Prevention (CDC). For this reason, Florida is a good bellwether state for the forthcoming RSV season.

According to the Florida Department of Health, RSV activity was low in all five regions, with no outbreaks but an increased positivity rate as of June 24, 2023.

From a prevention perspective, the CDC approved RSV vaccines for people ages 60 and older, using shared Clinical Decision-Making.

This means these individuals may receive a single dose of the RSV vaccine based on discussions with their healthcare provider about whether RSV vaccination is right for them.
