Severe forms of COVID-19 are more common in the descendants of Neanderthals. According to the results of the study, the scientists of the Institute for Evolutionary Anthropology of the Max Planck Society in Leipzig came to this conclusion.
As the authors of the scientific work explained in an article published on the pages of Nature, the recently discovered structures of one of the regions of the third chromosome increase the chances of becoming infected with a severe form of coronavirus. Man got these macromolecules from Neanderthals. This variation occurs unevenly in humans. About 30% of South Asians, 8% of Europeans, and 4% of US citizens have it. It is extremely rare in East Asians. For this reason, people living in the UK from Bangladesh die from coronavirus 2 times more often than Britons. In the third chromosome, it was also possible to isolate a dangerous genetic variation that can provoke a severe form of COVID-19. It includes the SLC6A20 gene and nearby sites. Its presence, according to preliminary data, doubles the threat of complications and death.
You should also know that the chance of getting infected is higher in people with the second blood group, in the presence of chronic diseases, in the elderly, and with a mutation that provokes Alzheimer's disease.
