My wife developed a fever on 6th july 2021 and for 10 days she had been running within the range of 37.1 - 37.6, we showed to the doctor and were advised some blood, urine tests & ultrasound. From the tests, it was diagnosed that she had an infection in the intestine. She was given some antibiotics, vitamins and probiotics. For a week she was ok but diarrhea persisted. But again, from the last 2 days, she started having a fever in the range of 37.3. We consulted a doctor and he wants to do some tests again including a stool test. We are unable to understand what the reason could be, can someone help us. I am getting worried and stressed out. Note: she has recovered from mild covid -19 in the month of may 21.
