No need to repeat once it is positive... contacts should take test on 5th day or prior if symptoms develop earlier..

The usual protocol is,  after getting tested Postive for Covid 19,we have to be in isolation for a total of 17 days from the day of onset of 1st symptom( not the day of testing ). If you were totally asymptomatic then you can take day of testing as Day 01. - If you want to take repeat test, you can go for Covid 19 Rapid Antigen Test, on Day 10.Even if it is Negative still you have to complete next 7 days of isolation( called Reverse quarantine) so that a total of 17 days is completed - otherwise you can ditectly take a 17 days staright isolation without testing in between.

Hi, you don't need to repeat the test. You can finish your quarrantine after 10 days or if you don't have fever for 3 days
