were do you get these questions from, there are different strains of hiv and 2 types of hiv (hiv+1 and hiv+2) hiv+1 is the more common type which is normally found in people from europe and america whereas hiv+2 usually effects the african community! but is possible for a non african to have this type but is very rare

This question has nothing to do with Africa. The question was about American vs. Central European HIV types. I suppose you misread it but for the record, Africa and Europe are the names of two different continents.

Here's a map of HIV-1 types:

http://en.wikipedia.org/wiki/File:HIV-1_subtype_prevalence_in_2002.png

As can be seen almost all HIV in North America is subtype N. Europe is also largely dominated by subtype N too but with a slight bit of other types in there. The same is true of South America which has a bit of subtype C in there too.

This isn't a fault on the part of Wikipeda - I screwed up and wrote N instead of B. The map is correct.

You are confusing Groups and subtypes. M,N,O,P are groups and under M there are A,B,C,D,F,G,H,J,K and CFRs subtypes.

Yes you are right. I wrote subtype N instead of B. And as you state, B is a subtype of group M (group N is extremely rare according to the article - just 10 cases as of 2006).

N and P groups are found in soutwestern africa. There is only one person at this time infected with group P.

But to get back to the poster's question. If the concern is if the HIV is different in Central Europe than in America the answer is that it in almost all cases isn't. It's the same group (M) and subtype (B) that is prevalent both places.

There is no getting back to the original posters questions this post is dead. There are no subtypes known that can't be picked up by the tests that we use at this point and doesn't concern anyone in this forum.

The original poster didn't ask about testability but about how easy it was to catch. If the subtypes are the same one would assume this was true for infectiousness as well.

Subtype C is predominant in Southern and East Africa, India and Nepal. It has caused the world's worst HIV epidemics and is responsible for around half of all infections.\

subtype C and CRF A/E are transmitted much more efficiently during heterosexual sex than subtype B.10 11 However, this theory has not been conclusively proven.12 13

This question was answered with the first response, and while the info about subtypes can be interesting and informative, there is no need to continue this discussion.

Thanks,
