Difference Between HIV 1 And HIV 2

Human Immunodeficiency Syndrome, also known as HIV, is a virus that is non-curable. With almost 1.2 million people in the US are living with HIV, its spread is something that is raising concerns the world over. Did you know that there are two types of HIVs, namely HIV1 and HIV2. Well, if you didn’t, you will now know exactly what is the difference between HIV1 and HIV2.

The main difference between HIV1 and HIV2 is its genetic distinction. In other terms, 55% of the genetic material of both viruses is different. So, this means that treatments and tests for both will not be the same. However, the mode of contraction of both HIVs remains the same, which is blood, breast milk, and sexual contact.

Another difference between HIV1 and HIV2 is that the former is the most common than the latter throughout the world.  HIV2 is known to have originated from West Africa. But it is now slowly being contracted in other countries as well. According to a report by the CDC, there were 166 cases of HIV2 in the US between 1988 and 2010. These cases were mostly linked or originated from West Africa.

The progression of both viruses in later stages is also another difference between HIV1 and HIV2. The former is likely to lead to AIDS, while the latter may not. This is because HIV2 has lower transmissibility than HIV1. Therefore, people living with HIV2 are non-progressors for a long time, while people with HIV1 progress quicker and end up contracting AIDS.

In order to make sure that you don’t contract HIV, consider going for HIV testing. Regularly getting tested for HIV and STD as well will ensure the safety of both you and your partner. With the alarming rates of HIV and STD today, getting tested for HIV or STD is the need of the hour.
