Question 1

I started having a fever, and since then, my doctor has been prescribing antibiotics. My question is whether consuming antibiotics for the past 9 days will affect the results of the Widal test. Can positive results turn into false negatives after taking antibiotics?

Question 2

My Widal test report shows:
S. Typhi O: 1:160 (positive)
S. Typhi H: 1:80 (positive)
I took medication for typhoid, but I still experienced headache, nausea, and giddiness. I consulted another doctor, who said the Widal report may not be reliable and it could just be a viral fever. Could you please clarify whether this report indicates typhoid or not?

Question 3

I tested COVID 19 positive and completed all prescribed medications while staying in home quarantine. For the last 7 to 8 days, I have been experiencing severe fatigue and a mild fever (99 to 100F). Yesterday, I tested positive for Typhoid. I am unsure if this is a lingering effect of COVID 19 or a true Typhoid infection. My Typhoid test results are:
AH: 1:80
BH: 1:80
TH: 1:160
TO: 1:320
Should I start antibiotics for Typhoid? Do I need any further tests to confirm the infection?

Yes, typhoid can sometimes resolve on its own, especially if mild. Blood test may give false positives due to past exposure. Confirm via blood culture. Vaccinated children can still get mild infection. Please consult a doctor for further evaluation.
