My father has cough since 2 months and since the past 5-6 days he has an on and off fever (between 99-102). He has weakness and feels cold sometimes but has no other general symptoms of Covid. Oxygen is 98-99 and pulse is 80-85 at all times. We took medication of a local doctor, he doesn’t have fever until the power of medicine stays then it comes back again especially in the evening/night time. What can this be? Is there a possibility we can treat this at home or is it necessary to get him tested for Covid? We fear that once we step out of the house there might be a possibility of attracting Covid even if he doesn’t have it. What can be done ?
