Federal health officials are trying to tell if this year's harsh flu season led to an increase in a rare but dangerous brain complication in children.

The U.S. winter virus season is in full force, and by one measure is the most intense in about 15 years.

While individual flu cases are not reported in Florida, the state did say that there were 13 outbreaks in eight counties, including two in Seminole County, one in Orange County, and one in Volusia County.

U.S. health officials say flu and COVID-19 infections are expected to ramp up in the coming weeks.

U.S. health officials say at least seven states are seeing high levels of the flu and that cases are rising in other parts of the country.

Flu cases remain high in Florida, and one doctor says we can expect the virus to be around for a few more months.

A perfect storm of respiratory diseases is increasing cases and hospitalizations across the U.S. and in Florida and could make for a terrible holiday season if more people don’t take precautions, according to the nation’s health experts.

The updated COVID-19 boosters, signed off on by the FDA and CDC last week, are shipping out to pharmacies and clinics across the country.
