Thank you for your query.
If the appropriate antibiotic to which the typhoid bacilli
is sensitive has been given then it shall take 48-72 hours for the temperature to return to normal. Unfortunately you have not shared the investigation findings and the medicines being given at present and so it is not possible to provide you all the guidance.
The precautinary measures that you need to take are:
1. Ensure proper food hygiene whether at home or outside as the infection spreads through feco-oral route.
2. Ensure that your daughter, and for that matter all family members, are vaccinated against typhoid.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
