Recovery after covid positive.

Hi Doc, Hope you are doing good. My husband had tested positive for covid and today is his 13th day from onset of symptoms. His ct score was 11/25 on 21st April  (9th day). D dimer was normal, feritinin and il6 was on higher end and he is on antibiotics, inhalers, steroids, anti coagulants as per doc advise. . His axillary temp remains 98-99 but still he has mild cough. please see the attached reports My query is can he end his isolation after 14th day if he still has mild cough and mingle with others in family ? Or do we need to extend his isolation? As there are elders n babies in home. Does he need to wear mask at home after ending isolation? Please advise on the protocol. There is too much confusion here
