Scientists have identified an edge in DNA that triples the risk of developing deadly COVID-19: a genetic quark has left Neanderthals. Passed over 50,000 years ago, it carries these genes today, about 16 percent of Europeans and half of South Asians. Scientists in Sweden and Germany compared the DNA of very sick patients with the Carnavirus virus to the Neanderthals and their mysterious sister group, the Denisovans.
A strip of DNA collected from the Neanderthals of Croatia created the possibility of patients being completely drowned in the worst collisions of the COVID-19 match.
If you have roots from outside Africa, about two percent of your DNA is Neanderthal.
However, when all these genetic fragments are pikeed together, more than half of the Neanderthal genome can be found in modern humans – and this makes the difference between humans, some carrying pieces, some carrying others.
Speaking to the BBC’s Science Focus magazine, Dr Hugo Zeberg, author of the study, published in the science journal Nature, explained how these genetic makeup trends seem to be at risk.
Referring to the discovery as “falling into his chair”, Dr. Zeberg said: “Initially we saw that copying the variant increased the risk by about one percent.
“You got a copy from your mom and from your dad.

Dr Zeberg said: “We have found that carrying these genetic variants is much more common in people who end up in hospital and ICU; therefore, among those who have a bad occupation of Covid-19.”
A separate study found that carriers of the variants also needed more mechanical ventilation.
Researchers believe that increasing the likelihood of sensitivity or virus infection and working less with how the body responds to catching it.
Dr. Zeberg acknowledges that genetic variants are a matter of “academic interest” in Neanderthals.
However, identification is ultimately a virus and it is important to have a better understanding of how it works.
He explained: “This could point to future COVID-19 treatment and help identify people at risk, and it could be very important in tackling the disease.”
Coronavirus currently has more than 46 million cases.
Meanwhile, 1.2 million people have died from Covid-19.
