Thanks for the query
of 101-102 for last 10 days is worry sum. Widal test
of 1:80 & 1:160 is not full proof evidence of typhoid
. A rising titre of four fold in comparison to previous one is really significant.If it is typhoid then treatment is oral or injectable antibiotic for 14 days. Generally it takes 5-6 days for fever to respond to antibiotic. If fever does not respond to antibiotic after 5 days then second line antibiotic is needed. You can go for blood culture
and typhidot test. I would suggest you to continue the antibiotic, maintain proper hydration and nutrition of the child. Make a temperature chart (6am-12pm-6pm-10pm) so that you can understand the trend and response to drug. You can also do tepid sponging to bring down the temperature.
I hope this answers your query well
Wish you and your family good health
