I was in close contact on monday with my assistant, he was tested positive for covid-19 this morning. when should i get tested?

COVID 19: 5 to 8 days would be a good time unless you become symptomatic before then.. “The mean incubation period is 5 days. About 97% of the people who get infected & develop symptoms will do so within 11 to 12 days, & about 99% will within 14 days.” REF: https://www.npr.org/sections/health-shots/2020/04/01/824903684/the-science-behind-a-14-day-quarantine-after-possible-covid-19-exposure

Agree with Dr. F: You should quarantine yourself for the next 10-14 days to avoid infecting others in case you acquire the infection and start shedding the virus. Wish you good health!
