The outbreak of coronavirus in the Chinese city of Nanjing, which has already spread to 26 cities inside the country, began with the infection of cleaners who were carrying out sanitary treatment of a plane that arrived from Russia. This was announced by the deputy head of the Center for Disease Control and Prevention of Nanjing, Ding Jie, reports by Aljazeera.
According to her, the study of the genome of the virus of 52 cases of infection associated with this outbreak has already been completed.
вЂњIn all cases, the delta strain and the genome sequence of the virus are highly similar, which means the same transmission chain. The sequence of the virus genome in cases of infection of cabin cleaners coincides with the sequence of the imported case detected on flight CA910 from Russia on July 10, вЂњ she explained.
Ding Jie noted that the sick airport workers who were engaged in cleaning the cabin of the aircraft may have become infected due to insufficient personal protective measures.
At the same time, the airline used the same staff for cleaning both international and domestic flights. Thus, the infection spread, she explained.
In total, 184 cases of infection have already been detected in the city.
At the end of 2019, an outbreak of coronavirus began in China. By March 2020, the World Health Organization declared a pandemic. According to the latest data, the number of cases worldwide exceeded 196 million people, more than 4 million of them died.
