These titres may suggest typhoid exposure, especially if symptoms persist (fever, fatigue). Confirm diagnosis with blood culture if possible. Antibiotic treatment may be needed.

My test report shows Salmonella typhi O is 1:160 and Salmonella typhi H is 1:80. Do I have typhoid fever? I have a fever every evening. After treatment, my ESR report is 18. I am 24 years old. I need a helpful answer.

Answered by Apollo Doctors

I have been experiencing fever around 104F for the past 3 to 4 days, which sometimes comes and goes, along with a bad sore throat, dizziness, flu symptoms, and fatigue. I had a Widal test for typhoid, and the result came back positive. The report also notes that titres in excess of 1:80 are probably significant.

Answered by Apollo Doctors

Can you explain what the Widal test means? If needed, I can share my blood test report. Also, what precautions should I take in the meantime?
