Hello and welcome to HCM!
Thanks for posting your query here.
The test you are saying about is WIDAL which will diagnose typhoid. It is a type of fever which is caused by Salmonella
It is not a TB nor HIV. So be relaxed. If the fever is more than 7 days there are chances of typhoid. Widal is only predictive test. The exact diagnosis can be made with the blood culture
. If it is positive it can be treated with antibiotics and antipyretics. Antibiotics like ceftriaxone
can be used and is curable completely.
To get out of the tiredness eat healthy and nutritious and easily digestable food. Take multivitamins which will give you strength. Fever causes dehydration
. Hence advised to take lot of fluids.
So dont worry. Have a happy recovery.
