New HIV strain discovered after nearly 2 decades

08 November 2019

This research marks the first time a new subtype of "Group M" HIV virus has been identified since guidelines for classifying new strains of HIV were established in 2000.

When it comes to HIV-1, there are four different groups: Group M, Group N, Group O, and Group P. Group M is responsible for the majority of the global HIV epidemic, but within Group M there are at least nine genetically distinct subtypes of HIV-1.

A senior faculty member at AIIMS, New Delhi, who did not want to be named said that sequencing of this strain is a significant development in understanding, prevention and treatment of HIV because it is part of what has caused the most infections in humans. Fauci said, "There's no reason to panic or even to worry about it a little bit". Not many people are infected with this. "This is an outlier". "Therefore, the CG-0018a-01 sequence will be important for determining the origins and age of subtype L", the researchers noted.

"It's actually misleading to describe genetic diversity from the [Democratic Republic of] Congo as a new subtype because the only useful meaning of the term "subtype" would come from identification of a lineage of the virus that has spread significantly beyond Central Africa", he said.

According to Mary Rodgers, senior author of the research and head of Abbot's Global Viral Surveillance Program, two strain were found in 1983 and 1990, while the third was detected in 2001. "This scientific discovery can help us ensure we are stopping new pandemics in their tracks".

The two strains were "very unusual and didn't match other strains", Rodgers said. "So scientists at Abbott and the University of Missouri developed new techniques to study and map the 2001 sample". There are two types of the virus: HIV-1 and HIV-2, the latter of which is relatively rare.

According to estimates, 37.9 million people across the world are now living with HIV, while 1.7 million individuals contracted the virus past year. "There is a very high likelihood that this new subtype, or any new group M subtype of recombinant form, would not behave differently to how it would be detected by diagnostic assay or respond to antiviral treatment", Shafer told Salon.

Forms of this new strain of the HIV might be circulating, both in the DRC and elsewhere, but are unclassified as of now. In order to utilize this technology, Abbott scientists had to develop and apply new techniques to help narrow in on the virus portion of the sample to fully sequence and complete the genome. She added, "We definitely don't work in isolation".

"We're making this new strain accessible to the research community to evaluate its impact to diagnostic testing, treatments and potential vaccines". She said, "We're not going to slow down. We can never become complacent, we need to be proactive and we're working to stay a step ahead of the virus".
