with titre 1:160 for 'O' and 'H' suggests typhoid
if correlated clinically.
Ideally for diagnosis of typhoid a paired sera with four fold fold increase in titre is required.
In case of typhoid widal test has significance only if there is fever
for more than 7 days. There are many condition in which test can be false positive.
You have not mentioned whether your fever has subsided spontaneously or you have taken any antibiotic. If you have started antibiotic then continue it.
If your fever has subsided on its own then I would suggest you to get a typhidot test and a repeat widal test done. If the titre is same or typhidot test is positive then take an antibiotic course for typhoid.
