Hi,
Welcome to Ask A Doctor.
Thanks for posting your query.
Little is known about the new strain of HIV. It is not a major type. It is just a deviation from subtype M identified as subtype L of HIV 1.
Its prevalence is not being assessed. We usually not detecting the subtypes in HIV testing. Treatment aspects also there is not much difference among subtypes. We used to differentiate either HIV 1 or 2 only.
When your HIV Rapid tests were Non-reactive after window period ruled out HIV infection and the non reactive 4th generation HIV Combo test for your partner also confirmed the same.

yes my tests were over 90 days after. is that out of the window period ?
Brief Answer:
You are free from HIV infection

Hi,
Welcome back.
Sero-conversion in a normal incompetent individual never exceeds 12 weeks after the exposure. So your nonreactive HIV test by 90 days was well beyond the window period.
You need not worry about HIV. Just avoid unprotected sex in the future.

As I mentioned already not much has been revealed about the new strain. As it is a subtype of HIV 1 and not other than HIV 1&2, it could also have been detected with the existing tests to my knowledge. More details and information yet to come.
