Hi. I understand your concern s. Maintain social distancing, mask and hand hygiene.

Hello madam. If your father has beaten the infection and is negative in the swab, it means that’s he is free of the infection. If he has not had fever for over 3 days and it is over 10 days since the first day of his symptoms, it is more likely that he is non infectious, ie he cannot transmit the infection to anyone else. I would strongly urge you to have the mandatory 7 day quarantine and then he can freely interact with members of the family.

It's always better to maintain social distancing and personal hygiene  .
