During its evolution, the coronavirus stopped mutating, adapting better to the human body and becoming more contagious.
The South China Morning Post quoted scientists from Hong Kong Polytechnic University as saying.
During the third wave of coronavirus in the city, the researchers identified the genetic identities of more than 20 patients by comparing samples of infection "imported" from abroad.
According to Gilman Siu, an associate professor at the institute, the coronavirus mutated during the first and second waves of the disease, but this time the results were different:
"Either the virus has adapted to the human body and stopped mutations, or in a short time all the infected people have been infected in one place."
Chinese professor David Huey agreed, saying that during the recent outbreak of COVID-19 in China's special administrative region, the virus was more contagious than the previous two waves. He argued that the latest virus could adapt more effectively to the human body.
