The body's response to coronavirus infection is largely determined by the genetic factor. Scientists from Sweden and Germany came to this conclusion according to the results of a recent study.

As the authors of the scientific work explained, this piece of DNA was inherited by humans from Neanderthals. Initially, it was used to protect the host from viruses, but in the case of COVID-19, presumably, the immune system fights more intensely, which weakens the host's body and provokes a severe course of the disease. This piece of DNA is inherited by about 63% of the population of Bangladesh. Moreover, a similar genome is also present in South Asians.
In turn, in Europe and East Asia, carriers of this macromolecule are no more than 10% of the population. It is extremely rare among African people, writes RIA Novosti.
