Although it has become a season when the temperature has risen and the chances of using the air conditioner have increased, overseas restaurants have reported cases in which it is believed that the new coronavirus infection has spread due to the flight of the air conditioner. . The American CDC = Disease Control Center is calling for adequate ventilation.
According to a report from the CDC, health authorities in Guangzhou, China, investigated the transmission routes of three different families confirmed to have been infected with the novel coronavirus from January to February, a total of 10 people. It turns out that everyone was having lunch at the same restaurant on January 24th.
The three families were seated in three separate tables arranged in a row as seen from the air conditioner outlet.
There were no windows in the restaurant.
At the table in the middle was a family from the Wuhan city, which was the most infected area in China at that time, and the family came the day before, one of whom developed after lunch that day.
According to the report, although there were no symptoms at the time, the flight from this one flowed downwind, infecting the family at the table next door, and further reflected by the strong airflow on the wall to the most windward. We conclude that the infection also seems to have spread to the family at the table.
The distance from the wall with the air conditioner to the opposite wall is 6 meters, and the virus gene was not detected from the air conditioner, and no other 73 guests on the same floor were affected.
