Can one person be infected with both HIV 1 and HIV 2?

Yes. While it is possible, it is very uncommon and infrequent.
Possible. Since hiv2 is found only in west africa, the probability of a person getting it along with hiv1 would be from having had blood contact with an infected person from that part of the world.

Could one infected with both hiv-1 and hiv-2 at a time?

Yes. Infection with either hiv-1 or hiv-2 is not protective against a superimposed infection by the other virus. So in theory, yes, one could get both in one individual. Hiv-2 is fairly uncommon in the us so infection with it is unlikely.

How are hiv-1 and hiv-2 different?

Subtypes. Hiv has two major types (in humans), along with several subtypes (called clades) of hiv-1. These clades are given subtypes of letters of the alphabet. These strains can create hybrids: slightly different genetic make-up from one another, sometimes called circulating recombinant forms. For the most part, hiv-2 is more difficult to transmit with a longer incubation period.
Different types. Hiv-1 and hiv-2 are different types of hiv. Hiv-1 comprises the majority of HIV infection in the world. Hiv-2 is usually found in africa, and rarely elsewhere. Both hiv-1 and hiv-2 can usually be detected through the usual hiv-1/2 antibody test. Hiv-2 is typically less aggressive/virulent and less transmissible (more difficult to pass from one person to another).

What are the differences between hiv-1 and hiv-2?

Source of infection. Hiv-1 is the more common form of HIV in the usa/europe, while hiv-2 occurs predominantly in west african nations, and former portuguese colonies, such as angola, mozambique, and brazil, and in parts of india (goa, maharashtra). Many hiv1 medications are effective against hiv2. Usa cases of hiv2 are projected to be several hundred, although estimates vary.

Can you please tell me how hiv-1 and hiv-2 differ?

Geography. Hiv-2 is found mostly in west africa or in people who come from west africa. It's similar to hiv-1, but may progress more slowly to aids. There are also some drugs, particularly nnrtis, that don't work against hiv-2.

What is the difference in testing for hiv-1 and hiv-2?

Different strain. Hiv-1 and hiv-2 both produce aids, both are lethal if untreated, infection spread same way. Hiv- 2 is less common mostly confined to west africa, genetic test will differentiate one from other.

Please help! What is the difference in testing between hiv-1 and hiv-2?

Different types. HIV-1 and HIV-2 are different types of HIV. Both HIV-1 and HIV-2 can usually be detected through the usual HIV-1/2 antibody test. However, HIV-2 is more than 55% genetically different from HIV-1. Due to this genetic difference, HIV-1 and HIV-2 antigens are distinct enough that if a test is developed only to detect HIV-1, it will not reliably detect HIV-2.

Whats the difference between hiv-1 and hiv-2 viruses?

Antigenicity. Hiv-1 is the major cause of aids in the usa. It differs from hiv-2 by its molecular structure. Hiv-2 has predominantly been seen in africa and appears less pathogenic than hiv-1, although the differences ultimately have little weight on outcome. An antigen is the chemical structure which stimulates the formation of antibodies, and the difference is a serological one.
