Thanks for writing in.
Your doctor is right in saying that a diagnosis of tuberculosis
cannot be made on the basis of a Mantoux test
Also, if it is a viral fever
, it can be expected to resolve on its own in 5-7 days.
If it doesn't resolve in 5-7 days and you have other symptoms like continuous cough or weight loss
, please get a chest Xray and a sputum examination for acid fast bacilli done.
Hope this helps.
