A Genetic Variant You May Have Inherited From Neanderthals Reduces the Risk of Severe COVID-19:

[...] SARS-CoV-2, the virus that causes COVID-19, impacts people in different ways after infection. Some experience only mild or no symptoms at all while others become sick enough to require hospitalization and may develop respiratory failure and die.

Now, researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) in Japan and the Max Planck Institute for Evolutionary Anthropology in Germany have found that a group of genes that reduces the risk of a person becoming seriously ill with COVID-19 by around 20% is inherited from Neanderthals.

[...] Last year, Professor Svante Pääbo and his colleague Professor Hugo Zeberg reported in Nature[1] that the greatest genetic risk factor so far identified, doubling the risk to develop severe COVID-19 when infected by the virus, had been inherited from Neanderthals.

Their latest research builds on a new study, published in December last year from the Genetics of Mortality in Critical Care (GenOMICC) consortium in the UK, which [...] pinpointed additional genetic regions on four chromosomes that impact how individuals respond to the virus.

Now, in a study published recently in Proceedings of the National Academy of Sciences (PNAS)[2], Professor Pääbo and Professor Zeberg show that one of the newly identified regions carries a variant that is almost identical to those found in three Neanderthals – a ~50,000-year-old Neanderthal from Croatia, and two Neanderthals, one around 70,000 years old and the other around 120,000 years old, from Southern Siberia.

[...] To try to understand how this variant affects COVID-19 outcomes, the research team took a closer look at the genes located in this region. They found that three genes in this region, called OAS, code for enzymes that are produced upon viral infection and in turn activate other enzymes that degrade viral genomes in infected cells.

"It seems that the enzymes encoded by the Neanderthal variant are more efficient, reducing the chance of severe consequences to SARS-CoV-2 infections," Professor Pääbo explained.

[...] They found that the variant increased in frequency after the last Ice Age and then increased in frequency again during the past millennium. As a result, today it occurs in about half of people living outside Africa and in around 30% of people in Japan. In contrast, the researchers previously found that the major risk variant inherited from Neanderthals is almost absent in Japan.

"The rise in the frequency of this protective Neanderthal variant suggests that it may have been beneficial also in the past, maybe during other disease outbreaks caused by RNA viruses," said Professor Pääbo.

    You had one. You just can't tell the difference between correlation and causation.

    Foof, mate, you're shitposting again.
    From the citation you provided (have you read it?)

    Chronic disease rates are higher among Indigenous Australians living in remote areas, particularly hypertension and diabetes [5]. Marginalisation from health services, food insecurity, and poor access to water, sanitation, and adequate housing that accommodates larger family groups, amplify COVID-19 risk. Social distancing and self-isolation are unrealistic where more than one third of Indigenous Australians (41.4%) in remote areas live in inadequate housing conditions, compared to just 1.9% of non-Indigenous Australians.

    And this is just for you from the same source

    Comparatively, in the U.S, health, socioeconomic, and cultural inequities among Native Americans have contributed to their overrepresentation among COVID-19 cases [11]. Similar concerns have been expressed by Native American leaders, emphasising the limited capacity of the U.S Indian Health Service to respond to the pandemic due to a chronic lack of government funding, and restricted health infrastructure [12]. Exclusion of Native Americans from COVID-19 racial demographic data published by government health departments, has also been highlighted by Native American leaders as discriminatory and misleading, meanwhile restricting the ability of Indian Health Services to prepare and respond appropriately [12].

    I can guess the restricted health infrastructure impacts your ability to read.

      Nothing you said contradicts anything I said. You just don't like that I'm correct, so you intentionally misread, misunderstand, and outright lie to yourself.

      Here is the only test to prove whether my claim is true or not: have dark folks had more severe cases of coronaids than less dark folks on average. And since you've found nothing whatsoever that disputes the absolute mountains of data around the world saying I am 100% correct, you need to just take the loss and move on.

        Mountain of evidence my ass.

        I'll let this convo drop, tho', it's a wasted time I can ill afford ATM.
