Beijing: Preliminary studies of mutated new strains of coronavirus suggest that their infectivity has increased by 10-70%. Feng Zijian, deputy head of the China Center for Disease Control and Prevention, said at a press conference on Wednesday.

“Recent preliminary studies of coronavirus mutations indicate that their infectivity has increased. The rate of secondary foci (SAR, the frequency of new infections among persons in contact with primary patients) increased, the growth ranged from 10 to 70%. The number of cases of morbidity in families has increased significantly”, - he said.

At the same time, he noted that there is no evidence yet that the new strains are characterized by a higher mortality rate among the sick.

“To date, we do not yet have evidence that the virulence of the new strains has increased, in other words, that the severity of the disease has increased”, - said Feng Zijian.

It is worth noting that according to WHO statistics, there are 97933 cases of the disease in China, 4801 people died.
