Fever issue. For my father on sunday!

Hi, I consulted through practo for my father on Sunday regarding fever. Please see the attached prescription screenshot. It was a five day course and the course is getting completed today. However, the fever has not yet subsided. He's having a fever which is ranging from 95-98°. The only thing in the prescription was, he was taking paracetemol since Sunday as dolo 650 was not available. But since today we had dolo 650 at home so he took dolo for now. Please suggest some other alternative as the though of covid-19 testing is only scary and simply unacceptable to us as it could also be normal viral. My sister and I both were closely taking care of my father but I had fever, and now I'm also doing a regular 5-day course through consultation. It's day 2 today.
