The ongoing COVID-19 cluster in Beijing was not caused by animals, according to the Chinese Center for Disease Control and Prevention.
The CDC said, “It is presumed to be mainly direct contact between people and/or indirect contact through the surface of contaminated objects.”
It also claimed the local outbreak was not caused by the same virus strains from Wuhan, once the epicenter of COVID-19 in China, nor the one spread in Beijing’s domestic cases before April.
Genetic analysis showed that the virus in the Beijing cluster relates to a European strain, adding the virus is “older” than the one that’s prevailing in Europe.
Last week, the World Health Organization also confirmed the coronavirus from Beijing’s new local cluster is closely related to the European strain after China shared the gene sequence data of the virus.
The Beijing cluster first emerged on June 11, leading to 280 local infections in 15 days, raising the alarm for the Chinese capital.
