Here's how coronavirus spread inside a government office in Florida -- and how one official says it stopped

Officials in Manatee County, Florida, were able to identify the patient zero in a recent outbreak of the coronavirus that swept through a government building and left two employees dead and several hospitalized, all of whom were unvaccinated.

Officials learned through contact tracing that the patient, an employee in the IT department, was infected by an unknown contact, Manatee County Administrator Scott Hopes said during a virtual news conference on Wednesday. The virus spread to four coworkers in the department, who were unvaccinated and unmasked. But another coworker who had direct contact and exposure to patient zero was not infected, because he was vaccinated, Hopes said.
