South Florida, especially the Miami–area, has reported the most new cases in the state and it's mostly due to socializing, Florida Gov. Ron DeSantis said during a news briefing Sunday.
The uptick in positive cases has been driven "by a big increase" over the last three weeks in younger age groups, particularly those in the 18-to-44 age range, DeSantis said. Graduation parties and gatherings where people aren't adhering to social distancing are responsible for several Covid-19 cases, DeSantis said.
A backlog of testing has also accounted for the current spike, DeSantis said.
Florida was in the 10% positivity range when testing ramped up in March and April, DeSantis said.
In April, that rate dropped and was stable in May and June, at around 3%. Positivity rate is about 12% now, DeSantis says.
