Thanks for the query. For infection to be labelled as typhoid, you need to test widal repeatedly and if the titre is increasing then only you can say it is typhoid fever. In your case ESR looks raised to me which might be due to some inflammation or infection. In typhoid fever there no special foods which are to be avoided. Just avoid junk food, outside water, outside food. Eat healthy nutririous home made food. Hope i helped you.
