Salmonella typhi O & H titres of 1:80 are borderline and may indicate past exposure or early typhoid. If there are no symptoms, treatment may not be needed. But if fever, weakness or gut symptoms are present, consult your doctor.

Take a Typhoid Test Test or Take a CBC Test (Complete Blood Count) Test

My 2 year 10 month old child has been having fever for the last 4 days. We did CBC and urine tests, which were normal, and dengue and malaria tests, which were negative. The fever subsided on the 5th day but returned on the 6th day, with the child head and body feeling very hot and temperatures above 101F. After taking Paracetamol 250 mg, the temperature temporarily reduced, but it rises again after about 6 hours.

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

S. Typhi O 1:40 dilution, S. Typhi H 1:20 dilution, S. Para typhi A H less than 1:20 dilution, and S. Para typhi B H less than 1:20 dilution are the results of the lab test. Is this typhoid severe and how many days will it take to cure?
