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.

Dr. Hema Suggests...

Take a TYPHIDOT IgG AND IgM Test or Take a COMPLETE BLOOD COUNT (CBC) Test

Hi, my 7 year old niece is suffering from typhoid with a high fever of 103 to 104 degree. Today her blood report shows a hemoglobin count of 5.9. The pediatrician has given sodium drips and injections to lower the fever, but it is still 101 degree a few hours ago. I am very concerned about the low hemoglobin count. Please suggest immediate action?
