Thanks for the query.
is so non specific in presentation that, almost any thing from a simple cough
, oral lesions, skin rash
to severe epileptic attack can be attributed to it.
I would try to answer your questions.
First of all, you are correct in saying that it might take few days for the test to become positive but that is not necessary, it might get positive within a month.
There are certain tests which become positive even within a week.
I recommend you to get a P24 or PCR done for hiv. these tests are positive within a week and are almost 100 % sensitive.
Even a single virus in your body can be detected by PCR.
If this test comes negative, you can be sure that you are safe.
Let me know if you have any other doubt.
