Scientists identified the source of the spread of coronavirus in China

UNITED STATES (OBSERVATORY NEWS) — Employees of the tropical botanical garden at the Chinese Academy of Sciences came to the conclusion that the coronavirus, whose source was considered the seafood market in Wuhan, got there from the outside.

Scientists analyzed the genomic data of 93 virus samples collected on four continents and found that the infection spread through at least three routes. Apparently, a certain “zero patient” infected someone in a Chinese city, and the crowded Huanan market turned into a hotbed of disease due to unsanitary conditions.

Experts checked 58 haplotypes obtained from 93 samples and made sure that they were divided into five groups, in which old (H1, H3 and H13) and new (H56 and mv2) were distinguished. All patients associated with the market were found to have the H1 haplotype and its derivatives (H2 and H8-H12), while some other infected Wuhan residents found the H3 haplotype, which is not related to Huangan.

Haplotypes detected in patients from other countries and Chinese provinces confirm that the market was not the primary source of the virus. Scientists believe that the transmission of the disease from person to person could begin in late November 2019, but the epidemic began after the infection reached the seafood market.
