S typhi O positive means active infection of typhoid fever. Active infection indicates the patient has an infection of Salmonella enterica serovar typhi. The Widal test is negative during the first week but still done to make a baseline of antibody titre. In the second week if there is four times rise in titre from the baseline then Widal test is positive.

It has been argued that PPV is the most important measure of a clinical diagnostic method since it represents the proportion of patients with positive test results that are correctly diagnosed[10]. At 1 : 160 titer, which is generally considered as a cut off point for positive Widal test, 6.4 and 11% individuals had positive Widal test for O and H Salmonella antigens, respectively.
In contrast, the same titre was observed in 10.2 per cent patients with other febrile illnesses of known etiology and in 1.8 per cent of normal children. The Widal test was developed over a century ago and remains one of the world's most widely used diagnostic tests but suffers from significant limitations in its sensitivity and specificity, as well as reliability. 110 Like most serologic tests, a false-negative Widal test may occur early in the course of illness, and a false-positive Widal test may result from past infection or from previous exposure to cross-reactive antigens or vaccination. Widal antigen titre is more than 1:160 in an active infection, or if TH antigen titre is more than 1:160 in past infection or in immunized persons is considered positive WIDAL test. As per your report it is within the normal range. Based on your symptoms further treatment has to be planned.

The causes of raised O or H titers other than active typhoid include: Widal test is said to be positive when “O” titre is more than 1:160 in person with Typhoid bacteria infection, or, if “T” antigen titre is more than 1:160 in a person who has had infection in the past or immunised.
