My mom is 55+ years and is diabetic. Few days back she had mild fever for 2-3 days. Then for a week she had a disturbed stomach. And was feeling a lot a weakness. Though her covid result is negative but some infection is found in lungs. Ct severity score is 11/25. The doc suggested to take fabiflu and scavista 12 mg. Please guide, is it actually cavity or some other sort of infection. An ready to share the ct report.
