1st new strain in hiv

You're referring to the discovery of a new strain of HIV!

Yes, in 2009, a new strain of HIV was identified, which was dubbed "Group M, subtype L" or "HIV-1 L". This new strain was found to be circulating in the Democratic Republic of Congo and was distinct from the previously known strains of HIV-1.

Here are some key facts about this new strain:

1. Discovery: The new strain was discovered by a team of scientists from the University of California, San Diego, and the Democratic Republic of Congo's National Institute of Biomedical Research.
2. Genetic differences: HIV-1 L has several genetic differences compared to other strains of HIV-1, including changes in the envelope protein (gp120) and the reverse transcriptase enzyme.
3. Transmission: The new strain is thought to have emerged from a common ancestor with other HIV-1 strains, but it has since evolved to become a distinct strain.
4. Prevalence: HIV-1 L is estimated to be present in around 1% of people living with HIV in the Democratic Republic of Congo.
5. Impact: The discovery of this new strain highlights the ongoing evolution of HIV and the need for continued surveillance and research to understand the virus and develop effective treatments.

It's worth noting that the discovery of new strains of HIV is not uncommon, and scientists continue to monitor the virus for changes and mutations that could impact the effectiveness of treatments and prevention strategies.
