HIV is an infection that debilitates the invulnerable framework. There are two primary sorts of this infection: HIV-1 and HIV-2.

The two sorts of HIV are long haul yet reasonable well being conditions. With powerful treatment, individuals with HIV can live long, solid lives.

Understanding the diverse kinds of HIV helps increment familiarity with the condition. In this article, we investigate the distinctions and similitude between HIV-1 and HIV-2.

Geology and Hereditary Qualities

HIV-1 is the most widely recognized kind of HIV and happens everywhere throughout the world. As per the HIV mindfulness philanthropy Turn away, around 95 percent of individuals living with HIV have HIV-1.

HIV-2 is for the most part present in West Africa, however it is gradually beginning to show up in different districts, including the Unified States, Europe, and India.

In spite of the fact that HIV-1 and HIV-2 are both retroviruses that can effectsly affect the human body, they are hereditarily unmistakable. A recent report uncovered that the genomes of the two infections just had a 55 percent grouping personality.

This implies not all tests and medicines work for the two kinds of HIV.


HIV-2 is harder for individuals to transmit than HIV-1. As indicated by one 2013 survey, the most widely recognized method of HIV-2 transmission is hetero sex. In any case, hetero transmission rates of HIV-2 are five to multiple times lower than those of HIV-1.

Among moms and infants, transmission rates of HIV-2 are 20– multiple times lower than those of HIV-1.

A man can contract either kind of HIV through direct contact with natural liquids that contain the infection, including:

  • Blood
  • Sexual Liquids
  • Bosom Drain

Hazard factors for HIV-1 and HIV-2 transmission incorporate sex without a condom and sharing needles or syringes.

In any case, there is little danger of transmitting HIV through sex if a man takes HIV meds effectively and can keep up an imperceptible viral load. This can likewise essentially decrease the danger of mother-to-youngster transmission.


The hereditary contrasts between HIV-1 and HIV-2 imply that if a man steps through an exam for HIV-1, it may not distinguish HIV-2. For individuals at expanded danger of HIV-2, a social insurance supplier may likewise test for HIV-2 antibodies or antigens.


To treat HIV, a healthcare provider usually prescribes a combination of several medications called antiretroviral therapy. Taking these medications daily as they instruct can slow progression of HIV, prevent transmission, and help protect the immune system.

Because of the genetic differences, a healthcare provider may prescribe different drug combinations for treating HIV-1 and HIV-2.

HIV-2 is less responsive to certain drugs that can treat HIV-1. These include:

  • non-nucleoside reverse transcriptase inhibitors
  • enfuvirtide

Though a healthcare provider may prescribe different drug combinations, they still monitor a person’s progress in the same way. This includes checking their viral load and CD4 cell counts, as well as looking for other clinical improvements.

Viral load

Individuals with HIV-2 will in general have a lower viral load, or the amount of the infection is in their blood, than individuals with HIV-1. Together with CD4 cell check, which is a method for deciding how solid the resistant framework is, viral load tells a human services supplier how well a man’s treatment is functioning.


HIV-1 and HIV-2 are the two principle kinds of the HIV infection. The vast majority living with HIV have HIV-1.

The two kinds of HIV debilitate the safe framework, yet HIV-2 tends grow all the more gradually and is less simple for individuals to transmit than HIV-1.

Hereditary contrasts between the two infections implies that there are a few contrasts in how social insurance suppliers analyze and treat HIV-1 and HIV-2.
