Fever and medicine. Advice is valuable.

Dear doctor, My mother(63)got cough due to fan air (she is allergic to fan air). Cough was rare in a day and slightly phlegm. She visited doctor and they prescribed some medicine and gave Dexona shot. Also checked her oxygen saturation it was good and checked her chest. She said no infection. After that in our family 4 members got fever and mild body pain(2 adults and 2 kids) . Only fever not other symptoms like cold, cough, loss of taste or smell nothing. Doctor prescribed paracetamol and azithromycin. We are talking steam and kadha along with medicine. Mainly we are not at all going outside from house. Is all fever related to covid. (please note one by one recovering slowly) Doctor said summer is viral fever time. But also suggested to check for taste and smell as well as oxygen saturation. If it is normal fever how long we should take paracetamol (5 or 6 days) Your advice is valuable. Thank you.
