Even though there have been some important new discoveries about the Human Immunodeficiency Virus (HIV), most people still don’t know how bad it is. Because of this, it has spread quickly through our culture and hasn’t stopped. Most people know HIV by its acronym, but there are actually two different strains of the virus, called HIV-1 and HIV-2.
HIV-1 is the most common type of HIV, and 99% of all HIV infections in the world are caused by it. Even though both viruses kill the body’s immune system (white blood cells) and cause disease in the same way, they are treated differently. If someone has been diagnosed with HIV, there is a very high chance that they also have HIV-1. But these two things are not the same in important ways.
Based on what VerywellHealth says, I’d like to explain the differences between HIV-1 and HIV-2 in the next post.
- Origin
It was found that the first people to get HIV-1 were chimpanzees and gorillas in west Africa. The number of people getting cancer because of HIV-1 is much higher in western African countries, like Nigeria. While the sooty mangabey, a type of monkey found in west Africa, was found to be the source of HIV-2, the virus itself was found in eastern Africa.
- Predominance
HIV-1 is more common than HIV-2 due to the fact that it can spread more quickly (it is more infectious) and that it can subvert the immune system of the body (more virulent) (more virulent). Because HIV-1 is so common, it is thought to be responsible for most cases of HIV.
- How many people got sick and how many died
HIV-1 is more likely to cause death and is more likely to spread than HIV-2. People who have HIV-1 or HIV-2 will eventually die from complications if they don’t get treatment. However, people with HIV-1 may have a higher chance of dying sooner because the disease moves quickly and causes more deaths.
- Diagnosis
Using a test called the Multispot HIV-1/HIV-2, you can tell which of these infections (HIV-1 or HIV-2) you have. People from west Africa or who aren’t getting better from HIV treatment need to get tested for HIV-1.
