Thanks for query,
Your daughter's widal test
shows positive titer for samonella Typhi O 1:320.
As she has no fever here in this case we have to see rising titer.It is important in this case.
Usually typhoid fever
is remain for a week initially.& then the widal test shows positive result after 10 days but as you have done it very early stage it may show its presence but when it is not rising it has no importance.
You just measure temperature every 2 hours for 2-3 days.If you find any elevation in it then you can go with ciprofloxacin
