Without your address it is hard to know the clustering of covid cases around you. As a rule of thumb we are treating every fever and cough case as potential covid unless proven otherwise.
If it is covid , you need to get a RTPCR done to be sure as your O2sats are below 95.
Fever and cough can subside from anywhere between 5 days to 15 days in my experience.
There are some unconfirmed reports of betadine gargle helping to fight off covid , if you are looking for homw remedies
