One-third of COVID tests came back positive for the novel virus in Miami-Dade County, Florida.
The county had a 14-day average of 24.87 percent, according to CBS News.
Even 20 percent would be considered very high by most experts and medical professionals.
The U.S. has set record-high rates for newly confirmed cases of the virus six out of the past 10 days.
There were just shy of 60,000 reported nationwide on Thursday.
