Scientists at the University of China’s Zhujiang Province have detected at least 30 strains of the virus known as SARS-COV-2, 19 of which are new, reports Daily Mail.
Some of the deadliest mutations are found in Zhejiang, as well as in several European countries. Stronger strains can generate 270 times the viral load compared to weaker variations. The weakest mutations are associated with variations that are common in many parts of the United States.
Tensions in China are among the most dangerous and include those that are common in Europe, writes the South China Morning Post. The weaker strains appear to be widespread in the United States. The results show, for the first time, that mutations can affect disease severity, the study authors explained. Their results have been uploaded to medRxiv.org.
For the purposes of the study, strains from 11 new patients infected with Chinese coronavirus were analyzed. Scientists are surprised to discover that the deadliest strains are found in Zhejiang, where the university is located. These mutations have also been observed in heavily affected European countries, such as Italy and Spain, before spreading to the epicenter of the epidemic between the United States and New York.
“The new coronavirus has acquired mutations that can significantly alter its pathogenicity,” the researchers note. They warn that weaker mutations do not mean that the risk of death is lower. Two patients in Zhejiang, one around the age of 30, while the other passed the age of 50, were seriously ill after contracting weaker strains. They both recovered, but the older one needed intensive care.
