Me and my whole family has been tested covid positive 5 days back and we have been having symptoms since 7 days. We all are taking azithromycin, paracetamol, vit c and zinc tablets. Since last 5 days my husbands fever is 100-101 and is not going down despite taking paracetamol 500 twice daily. He also feels slight tightness in chest while walking , sitting and doing any activity. His oxygen level is above 94 daily even after taking 6 min walk test. What i need to do, should he go for some tests and what other treatment is required. He has a history of fatal dengue affecting his lungs 13 years back.
