Hi my first symptom was headache on 26th oct and I got tested on 2 nd November with rapid test and it was positive. I am under home isolation. Initially I had cold but from past 5 days no cold or any other symptoms. Should I get retested after 17 days isolation period. Also my husband contacted me on 27th oct, from 28th we were self isolated and keeping distance and he had no symptoms and he got negative on 2nd nov, 2020. He is giving care and self isolated in different room. Does he need to take the test again?
