13 Apr 1989 HIV-1 and HIV-2 are etiologic agents of the acquired immunodeficiency syndrome (AIDS). HIV-1 is present on all continents, but HIV-2 is found

Among specimens confirmed to have HIV infection (true positives), Multispot and Western blot detected HIV-1 antibody in a similar proportion of cases (93.7% vs. 94.4% respectively) while Multispot and IFA also detected HIV-1 antibody in a similar proportion of cases (84.5% vs. 83.4% respectively).

This explains why HIV-1 is more widespread around the world than HIV-2. HIV-1 enters the immune system by attaching onto the CD4+ receptor found on the surface of certain white blood cells. HIV-2 has a harder time gaining such a foothold. So HIV-2 generally progresses much more slowly, with lower viral laod and slower risk of becoming sick. However, some HIV drugs (including NNRTIs) are not active against HIV-2.

Hiv 1 vs hiv 2

HIV-1, which was discovered first, is the most widespread type worldwide. HIV-2 is more than 55% genetically different from HIV-1. HIV-2 is most common in western Africa and is becoming more common in India, although numbers there are still relatively small. HIV-1 and HIV-2 also require different approaches when it comes to their treatment. For those who have HIV-2, some drugs that are effective against HIV-1 might be unresponsive.

HIV‐1 and HIV‐2 share many similarities including their basic gene arrangement, modes of transmission, intracellular replication pathways and clinical consequences: both result in AIDS. However, HIV‐2 is characterised by lower transmissibility and reduced likelihood of progression to AIDS.

Bệnh này là do Virus Khuyết Tật Người (Human Immunodeficiency Virus), thường được gọi là HIV. HVDSP : AIDS is caused by 2 known types of HIV. HIV type 1 (HIV-1) is found in patients with AIDS or AIDS-related complex, and in asymptomatic infected individuals at high risk for AIDS.

Two HIV virus types exist: HIV-1 is pandemic and aggressive, whereas HIV-2 is confined mainly to West Africa and less pathogenic. Despite the fact that it has been almost 40 years since the discovery of AIDS, there is still no cure or vaccine against HIV. Consequently, the concepts of functional vaccines and cures that aim to limit HIV disease progression and spread by persistent control of

Many STD tests in the U.S. are designed to detect the presence of HIV 1. This typically makes sense considering it is much more common, and that HIV 2 is practically unheard of in the country. Still, some advanced HIV tests can detect both the presence HIV 1 and/or HIV 2 antigens.

Before the 4th-generation HIV-1/2 Ag/Ab and HIV-1/2 Ab differentiation immunoassays for HIV testing became widely available, clinicians suspected chronic HIV-2 infection in certain clinical scenarios, such as a declining CD4 cell count in an HIV-1–seropositive, untreated individual with an undetectable HIV-1 plasma viral load, or an opportunistic infection in an individual from West Africa hiv 1 vs.

HIV-1 appears to outcompete HIV-2 with progressive disease in HIV-1/2 dual infection, as evidenced by low or undetectable HIV-2 plasma viral and proviral loads (when compared with high viral loads However, it seems that HIV-2 is less easily transmitted, and the period between initial infection and illness is longer in the case of HIV-2. Worldwide, the predominant virus is HIV-1, and generally when people refer to HIV without specifying the type of virus they will be referring to HIV-1. Influence of HIV-2 infection on survival.

HIV-2 has a harder time gaining such a foothold. So HIV-2 generally progresses much more slowly, with lower viral laod and slower risk of becoming sick. However, some HIV drugs (including NNRTIs) are not active against HIV-2. HIV can be divided into two major types, HIV type 1 (HIV-1) and HIV type 2 (HIV-2).

29 Dec 2020 Pregnant women with HIV-2 should be treated as per guidelines for HIV-1 mono- infection but using antiretroviral (ARV) drugs that are active

These days, the news about HIV/AIDS is mostly good. We're hearing about "functional" cures, better drugs, fewer side effects and longer lives. There are 29 Dec 2020 Pregnant women with HIV-2 should be treated as per guidelines for HIV-1 mono- infection but using antiretroviral (ARV) drugs that are active Positive HIV-1 antibody, but negative HIV-2 antibody results, indicates the presence of HIV-1 infection.

HIV-1 accounts for around 95% of all infections worldwide. On a structural level HIV-1 and HIV-2 have important genetic differences. A technical description of the difference is that the vpu gene found in HIV-1 is replaced by the vpx gene in HIV-2. HIV can be divided into two major types, HIV type 1 (HIV-1) and HIV type 2 (HIV-2). HIV-1 is related to viruses found in chimpanzees and gorillas living in western Africa, while HIV-2 viruses are related to viruses found in the sooty mangabey, a vulnerable West African primate.

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. 2020-06-07 HIV-1 and HIV-2.
