MIAMI — With a new wave of omicron COVID cases surging in Miami-Dade County, the percent of local positive tests, known as the positivity rate, has soared, representing a fourfold increase since April and likely an undercount due to at-home testing.
On Monday, Miami-Dade County’s seven-day average COVID-19 positivity rate rose to 22 percent, up from a 5 percent rate on April 8, according to the county’s COVID-19 Daily Dashboard. The latest number is nearing the rates at the height of the omicron surge in January, when positivity rates scaled 35%.
“We should definitely be concerned now,” said Mary Jo Trepka, an infectious disease epidemiologist and professor at Florida International University. “In fact, we should have been concerned several weeks ago.”
