New strains of HIV after 12mth exposure

I have read recently online that a new strain of HIV has been found in Africa? does anyone know how these new strains were detected in the first place and would modern HIV testing detect possible new strains by a cross reaction/common connection? i have had several routine tests within the last 12mths (3 tests since a possible exposure in africa, condom break with a CSW) all have been negative in an NHS gum Clinic, is it safe to say that i can rule out being infected with a new strain?  im just about to start a new sexual realtionship and im really worried that i could have a rare strain that current testing wouldnt pick up. How can i rule this out, it causing me sleepness nights.... over the past 12mths my health has been fairly good, i have only had one really bad chest infection but every couple of weeks i have really bad night sweats. do you think that i should continue to test and if so what test should i use or can i 100% say that im hiv negative?

Hello,
Thank you very much for your post and welcome to our forum.
Provided you have been tested at least three months after the incident with either a third or a fourth generation HIV test, these can certainly detect the vast majority of all HIV groups and subtypes within HIV-1 and HIV-2, even the rarest of subtypes. In any case, it is believed by most virologist that all subtypes (even the newest and rarest) can be detected with these tests as they all share similar structural characteristiscs.  Therefore I can assure you that from what you are telling me, that you are definitely HIV negative.
Best wishes,
Dr José

Thank you for your post doctor it really helps. I had my tests at a NHS gum clinic, I'm not too sure what test they used.I have been told that all current/new strains would produce the same antidoies and antigen is that true. Do you think I should continue to test to rule out rare strains. Sorry if this is a stupid question?

Doctor, the reason why I'm asking you these questions is because I read an article on google about a women from cameroon living in paris and a man in new york having rare strains of HIV. Are u aware of these reports and if so did they test positive with current testing and the new strain was identified after by further testing?
