One person infected about two dozen passengers on a Chinese bus with poor air circulation Corona virus According to research published on Tuesday that provides fresh evidence, although many are not sitting close The disease is spread in the air.
Health authorities initially downplayed the possibility that empty breathing sent infectious micro-droplets into the air, but U-turned Experts pile on pressure And evidence mounted.
The article, published Tuesday in JAMA Internal Medicine, examines the risk of airborne infections by taking a closer look at travelers who make a 0-minute trip to a Buddhist event in the eastern Chinese city of Ningbo in January before becoming a regular face mask in January. Virus.
Researchers believe a passenger, whose gender is not known, was patient zero, as the man was in contact with people in Wuhan, the city where the infection came out late last year.
Scientists mapped out where other passengers were sitting and also tested for the virus, then confirmed that 23 of the 68 passengers on the same bus were infected.

Significantly, in the front and rear of the bus, outside the perimeter of three to six feet, officials and experts say the infected droplets can travel from the infection.
On top of that, the sick passenger had not yet shown symptoms of the disease, such as a cough, when the group made their trip to a religious event.
The researchers also noted that air conditioning easily re-condensed the air inside the bus, which could have spread the virus. Contributed.
“Investigations indicate that, in a closed environment with air recirculation, SARS-Cavi-2 is a highly transmissible pathogen,” he wrote, referring to the name of the virus.

“Public health is of paramount importance in our search for potential airborne transmission.”
His study, which included a diagram showing each infected passenger seated, adds to the evidence of airborne transmission, including research into how the virus spread between the tables of people eating at a restaurant in the southern Chinese city of Guangzhou.
