Where Did the Group N Strain of HIV Come From?

Probing the Origins of Group N

Also referred to as group new, not-M, and not-O, the group N strain of HIV was discovered in Cameroon in the 90s. In fact, group N infections are still largely restricted to Cameroon, though the strain has cropped up in other populations (typically those who have had contact with someone from the area where the strain is most prevalent).

Does the Group N Strain of HIV Cause Different Health Effects?

Because group N is so rare, researchers are still working to gain a full understanding of it. This strain has distinct genetic differences from group M, which is the most prevalent strain of HIV and the strain responsible for the worldwide AIDS crisis. Some findings indicate that the group N strain is less affected by drug therapies, which could pose complications during treatment.

How Can You Reduce Your Risk of Acquiring HIV?

Despite the differences between HIV strains, all forms of the virus can be avoided by taking the following steps:

• Always use condoms when engaging in sexual intercourse
• Avoid the use of intravenous drugs or only use sterile needles
• Talk about sexual health and STI testing with your partners
• Consider pre-exposure prophylaxis (PrEP) if you have a higher risk

People with a higher risk of acquiring HIV may also be encouraged to undergo yearly testing. Frequent testing helps people identify positive status, which can help prevent transmission to others.
