Over the years, HIV has become increasingly manageable to live with thanks to the invention and the availability of advanced medicines, but scientists have recently discovered a new strain of the virus for the first time in nearly 20 years.
Notably, these and other headlines around the web frame the discovery as a big concern.
Two sequencing studies of HIV in India conducted between 2000 and 2007 had indicated that HIV-1 subtype C was the dominant virus, accounting for more than 95 per cent of HIV infections.
The study published online on Wednesday in the Journal of Acquired Immune Deficiency Syndromes described the previously unidentified strain of HIV under the Group M, which is responsible for the vast majority of human infections. According to the guidelines in 2020, to classify this new subtype, three cases must be discovered independently.
"Identifying new viruses such as this one is like searching for a needle in a haystack", she said.
The new strain is classified as, "subtype L In HIV-1 Group M".
Since the beginning of the global AIDS pandemic, 75-million people have been infected with HIV and 37,9-million people today are living with the virus. It is important to know what strains of the virus are circulating to ensure that tests used to detect the disease are effective. This strain is very rare, and expected to have the same response to existing antiretroviral therapies, which work incredibly well; if diagnosed early, HIV positive people now have almost the same life expectancy as those who are HIV negative. Her company tests more than 60% of the world's blood supply, she said, and they have to look for new strains and track those in circulation so "we can accurately detect it, no matter where it happens to be in the world". However, scientists are confident that with enormous advances in medical technology since the New York Times reported on a "rare cancer seen in 41 homosexuals" in July 1981, they will be able to effectively test for and treat the recently verified subtype. Both subtypes and sub-subtypes of the HIV-1 M group are believed to have originated from a single chimpanzee-to-human transmission.

"By advancing our techniques and using next-generation sequencing technology, we are pulling the needle out with a magnet".
In this instance, the first two were discovered in the Democratic Republic of the Congo in 1983 and 1990 respectively.
The third sample, they said, was hard to sequence at that time because of the amount of virus in the sample, and the existing technology. At the time, there wasn't technology to determine if this was the new subtype.
He added that identifying a new strain provides a more complete map of how HIV evolves.
Indeed, new subtype discoveries have been a result of full-genome sequencing, and have helped identify unique recombinant forms.
Dr. Robert Shafer, a professor of medicine at Stanford University, agreed with Henrich's assessment. But there is also some evidence of subtype differences in drug resistance.
