HIV-2 and other types

[Trueman2011]

HIV 2 wasn't discovered for a time after HIV-1. I'm curious to know how HIV-2 was discovered? Each type forms different type of antibodies. A person with HIV 2 would show negative on HIV-1 antibody test. Then how was HIV 2 discovered?

Maybe one unlucky person got HIV 2 and develops aids and after serious complications, and after thorough analysis, doctors discovered the new virus?

My concern is even with the rare subtypes and groups. How did we discover them in the first place? Maybe new subtypes may show positive on HIV 1 antibody test, But the other new groups and HIV 2?

If you believe you have been exposed to HIV and want help to judge your risk, would like advice about HIV testing, or have questions about the effectiveness of condoms or risks associated with specific sexual practices, this is the site for you.

Please answer. This is my last question ever. I will definitely move on after this.

How are different types/groups of HIV formed?

1.Are they mutated versions of the earlier types ?
                                 or
2.They were already existing in nature but were discovered later.
                                 or
3. Are they formed from analysis/experiments of HIV going wrong in the lab. Is it possible to manipulate/modify HIV in the laboratory?

Move on.

Just make sure you don't expose yourself to any of these HIV risks: unprotected anal/vaginal sex or sharing needle and you won't be exposed to HIV, common or rare strain.

It is VERY RARE to get HIV-2 so, you don't need to worry about something that does not exist, like a rare type that hasn't been found, that you may have. Its not going to happen.

An HIV expert will tell but existing HIV strains can be detected by most, if not all, approved HIV tests.

[Trueman2011]

Sir, please don't get me wrong. It was never in my intention to get you to type a long post explaining me about the origin of HIV. I'm just concerned , tat's all.

If i happened to contract a new type of HIV (unknown before or mutated one), how will i ever know. I know that a person can live with HIV without any symptoms or treatment for many years. How would we know if we get a new form of HIV?

[Hope242]

The same man who discovered HIV-1, discovered HIV-2. AIDS was discovered first and then the virus HIV was found to be the cause. Most tests detect HIV-1 & HIV-2.

Then I suggest you go pay someone to take the time to explain it to you.

[Trueman2011]

I am afraid to look in the internet for info like these(health issues). Don't know what to believe and what not to. Some information can be panicking. That's why i wanted to hear it from experts. Or maybe you know a site for reliable info.......

Look up the history of HIV 2.
