This suggests significant typhoidal exposure, likely acute typhoid. Confirm with blood culture & Typhoid IgM values if fever persists. Antibiotics may be started.

Widal test report shows S. Typhi O 1:40 positive, S. Typhi H 1:160 positive, S. Para Typhi AH negative, and S. Para Typhi BH negative. Is this typhoid high, medium, or low? What are the common medicines for this?

Answered by Apollo Doctors

My Widal report shows S. Paratyphi A from 1/20 to 1/160 are all positive, S. Typhi H and O are positive at 1/20, and S. Paratyphi B is negative. All other sections are negative. Do I have typhoid disease? What should I do regarding this? Is it in a lethal or dangerous condition or is there no need to be anxious?
