“A step forward?” New strain of HIV discovered for the first time since 2000

From Daily Mail: Scientists have identified a new strain of HIV – the first to be discovered since 2000.

The newly-discovered strain belongs to the same sub-family of the virus responsible for the pandemic that began in 1981 in Sub-Saharan Africa, spread around the globe and has killed 32 million people.

It belongs to Group M of the virus and was identified in three people in the Democratic Republic of Congo by scientists at Abbott Labs, which makes HIV diagnostic tests. The family of viruses is still the one that most commonly infects humans.

Although it may represent an evolution of the virus, the new HIV strain contains the necessary similarities to previously discovered Group M ones to still be diagnosed and treated using existing methods.

But the discovery of this strain – and all others of HIV – could be a step forward in their understanding of how the virus evolves, how to diagnose and treat it and to the development of a potential vaccine to end the pandemic for good.

‘This discovery is just the tip of the iceberg,’ said Dr. Mary Rodgers, a principal scientist at Abbott and a study co-author. ‘Abbott is making this new strain available to the research community globally to evaluate its impact to diagnostic testing, treatments and potential vaccines.’

This is the first time a new subtype of Group M HIV has been identified since classification guidelines for parsing out the various strains were established at the turn of the century.

Researchers say the new discovery helps them to stay one step ahead of a mutating virus and avoid new pandemics. They’ve actually been aware of the novel strain for some time, but DNA sequencing technology was insufficient to confirm it as new, until now.

Before an unusual virus can be determined a new subtype, three cases of it must be discovered independently.

The first two samples of the new HIV-1 Group M, subtype L were discovered in DRC in the 1980s and the 1990s. The third, collected in 2001, was difficult to sequence at the time because of the amount of virus in the sample and the existing technology.

Global healthcare company Abbott made the discovery, which is published in the Journal of Acquired Immune Deficiency Syndromes (JAIDS).

‘In an increasingly connected world, we can no longer think of viruses being contained to one location,’ Carole McArthur, professor in the departments of oral and craniofacial sciences, University of Missouri, Kansas City, and one of the study authors, said.

‘This discovery reminds us that to end the HIV pandemic, we must continue to out-think this continuously changing virus and use the latest advancements in technology and resources to monitor its evolution.’

Latest genome sequencing technology allows researchers to build an entire genome at higher speeds and lower costs.

In order to make the most of this technology, Abbott scientists developed and applied new techniques to help narrow in on the virus portion of the sample to fully sequence and complete the genome.

The new Group M strain will not change the way HIV is diagnosed or treated, and simply means that people are tested for the new strain as well.

Existing diagnostic tests and anti-retroviral drugs, which suppress the growth of HIV, are designed to target the parts of the virus that are common to all groups.

Dr. Michael Brady, medical director at HIV charity Terrence Higgins Trust said: ‘Scientific progress in our understanding of HIV continues to move at a fast pace. It’s important to stress that there are many different strains of HIV, but our ability to detect and treat the virus remains the same. Thanks to medical advances, HIV is now a long-term manageable condition and people on effective treatment can’t pass the virus on.’

An estimated 47 percent of people who are living with HIV are considered ‘virally suppressed, meaning that treatment has lowered the load of the virus in their blood sufficiently so that it cannot be transmitted to other people.

‘We now have the tools to end new HIV transmissions once and for all, and breaking down barriers to testing will help us achieve that goal.’

There is no new strain of HIV because there is no old strain of HIV. ” HIV” does not exist as an exogenously acquired viral pathogen, only as a laboratory artifact, probably a human endogenous retrovirus, contained in the human genome by the dozens and expressed under conditions of severe oxidative stress. Retroviruses aren’t really viruses anyway. The “viral” entity that they claim is HIV doesn’t do anything, it just sits there. When culturing it the cultures have to be artificially stimulated to even get it to be expressed. Plus it only has eight genes, not enough genetic information for… Read more »

It cannot be over-emphasized that the HIV/AIDS paradigm is the “scientific” equivalent of The Climate Crisis (OMG!), pure fantasy, as insubstantial as smoke. Actually that’s not true, smoke at least exists. Anyone who reads the medical literature will be convinced of this, although much of that literature has been memory-holed. I’ve archived some of it if anyone is interested. Reading the faux-science drivel of these “researchers” is like listening to slimy politicians promising to “make our communities safer through common sense gun control legislation”. It’s all so very tiresome. IMO HIV/AIDS – The Movie was created by TPTB as a… Read more »

I watch a weekly medical show on PBS and was surprised today’s guest was talking about how expensive it was to get a “Prep” medication to protect him sexually. I looked it up. It’s the Rx med I keep seeing TV ads for, but never knew what it’s for: Truvada. It’s to *prevent* HIV transmission… It was initially developed to prevent transmission during birth. Then they found out that giving it before and after exposure protected monkeys from getting HIV when it was injected, at 100% rate of success. Monkeys… So he’s gay and doesn’t want to stop what he’s… Read more »

Folks have been traveling to exotic places and exploiting the natives sexually since at least the 16th century but AIDS/HIV never existed until the 1980’s. AIDS is a medical construct and in homosexuals it is a consequence of EXTREME promiscuity involving highly unnatural sex acts as well as drug abuse – the supremely hedonistic “gay lifestyle” from the 1970’s onward. In Africa it is simply clusters of old diseases, mainly exacerbated by malnutrition, with a new name – AIDS. There is no “AIDS pandemic” in Africa, the population is exploding there, despite that continent being in the midst of, so… Read more »
