Coronavirus became more dangerous because of the mutation

The pathogenesis of a coronavirus disease may vary depending on the pathogen strain. This was stated by the scientists at Zhejiang University.

Researchers examined samples of various coronavirus mutations from random patients from Hangzhou and evaluated how quickly different strains penetrate and destroy human cells. The authors of the study insist that the most aggressive strains of the causative agent COVID-19 can reach 270 times greater viral load than their less powerful counterparts.

The most aggressive strains of coronavirus were found in patients in Italy and Spain. The strains of the virus found in the USA turned out to be the least active, but more common. The strains found in China were among the most dangerous and similar to those that are distributed in Europe. But in New York - the epicenter of infection in the United States - the most dangerous strains were discovered.

We mau note that the newspaper The Hill on April 9 reported that the geneticist from the School of Medicine Ikan Harma van Bakela expressed confidence in the European, and not Asian, origin of the strain of coronavirus detected in New York. A similar conclusion was reached by a group of scientists from the Grossman School of Medicine at New York University.

Zhejiang University scientists believe that they were the first to find evidence that mutations affect the severity of the disease. He argues that weaker mutations do not mean a reduced risk of death for all groups of patients. For example, both the 30-year-old and the 50-year-old patients from Zhengjiang were infected with weak mutations, while for both the disease was quite severe.

At the same time, the number of patients with no symptoms of coronavirus is growing. In Moscow, for example, more than 60% of patients showed no symptoms .

Recall that Israeli experts are trying to create technology for voice analysis of health status, including in order to identify patients with coronavirus by voice.

To the date, almost 2.5 million cases of infection with a new coronavirus infection have been detected in the world. 170 682 patients died. Almost 650 thousand people recovered.
