An immune response to the virus (antibodies/Ab). Genetic material from the virus (HIV RNA or DNA). In this section we describe the main HIV … 2018-08-23 HIV-1 and HIV-2 are classified as retroviruses, and the two have the same impact on the body. However, according to the research of scientists who are specializing in HIV, the two types are genetically different from each other.

HIV-2 är mindre smittsamt och begränsat till Västafrika. HIV-1 fue descubierto primero y es un mundial más frecuente, mientras que HIV-2 es menos patógeno y se linda We use cookies to enhance your experience. By continuing to browse this site you In these tests the antigen being tested is a major HIV protein called p24. p24 (short for protein 24) is produced 2–3 weeks after infection and before antibodies are produced.

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.

Indeterminate HIV-1 antibody but positive HIV-2 antibody results indicate the presence of HIV-2 infection, with probable cross-reactivity of HIV-2 antibodies with HIV-1 antigens on the assay strip. Verification of a first-time positive test result is recommended for the diagnosis of HIV-2 infection, by submitting a whole blood specimen for FHV2Q / HIV-2 DNA/RNA Qualitative Real-Time PCR. HIV can be one of two types: HIV-1 or HIV-2 although HIV-1 is far more common throughout the world and especially in the United States where it accounts for 99.99 percent of all HIV diagnoses. Worldwide, that percentage is still an overwhelming 95 percent. Testet har förmåga att detektera hiv-1 (genotyp A-J), inklusive ‘O’ cluster virus samt hiv-2. Positivt fynd måste alltid verifieras med specifika Ag och Ak tester. För att utesluta hivinfektion vid negativt testresultat rekommenderas sex veckors uppföljningstid efter misstänkt hivexposition, eller efter avslutad PEP/PrEP- profylax.

Distinguishing between HIV-2 and HIV-1 is important because their clinical management differs; HIV-2 does not respond to some antiretroviral drugs effective on HIV-1, and HIV-2 cannot be measured by HIV-1 viral load tests. Indeterminate HIV-1 antibody but positive HIV-2 antibody results indicate the presence of HIV-2 infection, with probable cross-reactivity of HIV-2 antibodies with HIV-1 antigens on the assay strip.

Although tests which are sensitive to both types of viruses are widely available, only one antibody test currently available can specifically distinguish between antibodies to HIV-1 or HIV-2. Worldwide, the predominant virus is HIV-1. HIV-1 accounts for around 95% of all infections HIV-2 is mainly seen in a few West African countries. The spread in the rest of the world is negligible.

When clinical progression occurs, both diseases demonstrate very similar pathological processes, although progression in HIV-2 occurs at higher CD4 counts. The difference between HIV-1 and HIV-2 are as follows. HIV-1 is the most common type of HIV and accounts for 95% of all infections, whereas HIV-2 is relatively uncommon and less infectious. HIV-2 is mainly concentrated in West Africa and the surrounding countries. HIV-2 is less fatal and progresses more slowly than HIV-1.

For those who have HIV-2, some drugs that are effective against HIV-1 might be unresponsive. The genetic differences between the two HIV types are the main reason why it happens, and it can be confusing what drugs will work as a treatment without consulting a This strain is less likely to progress and many of those infected remain lifelong non-progressors. Progression is slower. Average level of immune system activation are higher. Average level of immune system activation are lower. During progression, HIV-1 has lower CD4 counts than HIV-2. Another notable difference between HIV-1 and HIV-2 is their degree of virulence and infectivity.
