Day 4 working with covid positive people The frist 3 day are the worst for the ones who show  symptoms.  My opinion out of the 6  that i take care for   1 definitely had it . The others  i bet where false positive , which happened  to one of the staff  he tested  positive and 3 days later after another test which came back negative.  My numbers could be off but i can probably say without a doubt that 1 in 6 test are positive . I am just going by what i have seen  in person.
