When can you test for covid?

Can or should: Testing procedures are set forth by local health officials. In the USA we have self directed test sites scattered throughout the country where anyone can test anytime. What the process is in South Africa is not information we have access to. I would contact a local health agency for the local procedure.I believe they have an on line assessment tool to screen patients.

COVID 19: Average incubation period for COVID-19 is 2 to14 days (but as little as 1 day), median time is 4-5 days. You have more chance of having an accurate test result if you have symptoms or you wait 5 to 8 days after COVID 19 contact.
