Thank you for your query.
I am sorry to know that your daughter is suffering a lot.
There is a chance of viral infection.
But other infection should be considered also.
is another possibility.
Give her oral re hydration salt for dehydration
for increased temperature.
I think it will be OK within 2-3 days if it is not complicated.
If the temperature continue to rise then the enteric fever
should be excluded.
I think I have been some help of your query.
