JACKSONVILLE, Fla. Theres a new site conducting rapid testing for the novel coronavirus. Millennium Physician Group opened rapid testing to their patients and the public Wednesday. Doctor Rodas noted one big issue with rapid testing is that the tests cannot detect coronavirus in the body until 2-5 days after infection. However, thats not to diminish that rapid testing could help prevent the spread at the convention. I believe we need to let the providers and the physicians have a little bit more input into the testing, Rodas said.
