Hi Thanks for Using HCM,
There is nothing to worry as Typhoid detected in early stage.
Did he suffer from diarrhoe?
If so dont allow him to be dehydrated (If he is in Hospital then no need to worry as I.V fluids will help in rehydration )
Avoid spread of typhoid to others by Hand hygiene and intake of Hot Water only
Nature of Typhoid fever
is Relapsing so continue Antibiotics
I hope this is useful.
