My father has fever(99.2F) since last Saturday. He has taken azithromycin(once daily for 5 days), paracitamol(2 twice daily) till yesterday. Today again he got fever. Fever comes in the afternoon. He has upset stomach since sunday and uses washroom for approximately 3-4 times on an avaerage. Stool is not watery. He had alergy type symtom on sunday,monday and tuesday. He took cetrizine 1 tab on monday and alegra 2 tab on tuesday. Now that symptom has subsided. He has done a few tests(covid-result pending, CRP,Urine r/e, malaria, dengue and LFT). He doesn't have breathing issues or cough/cold or sore throat. He had body ache and then the got fever. Now he doesn't have body ache. He can smell and taste. I checked in oxymeter its showing 98/99. Please help me as I am really worried now about him as the fever is not subsiding. He was told by the team who did covid test that if it comes positive then they will call otherwise they won't. They asked us to get the report on Monday.
