with titre 1/160 for S.Typhi O is positive. A single raised titre is of little value and a rising titre of four fold suggests typhoid
. But as child is having fever with raised titre treatment should be given if there is no other cause for fever. So I would suggest you to consult a physician if fever recurs to rule out the other causes of fever and if needed then get a prescription of oral antibiotic ( cefixime
) for typhoid. Maintain a temp chart and give paracetamol
to control the fever.
