Study Says Air Conditioner May Play a Role in Spreading the Corona Virus.
Air conditioner is used to dispel hot air in the room. But a recent study said the Air Conditioner plays a role in the spread of the corona virus.
The study was led by Jianyun Lu from the Guangzhou Center for Disease Control and Prevention. The team studied 10 different cases in 3 different families who ate at the same restaurant in Guangzhou. This is based on cases of infection in Guangzhou at the end of January.
“Strong air flow from the AC can spread droplets,” wrote in a study report quoting from Science Times.
The first patient from 10 cases studied was found to be returning from Wuhan on January 23, 2020. Whereas Wuhan was the source of the first virus spreading since December 2019. The patient had dinner together with three family members the following day. The restaurant does not have a window and only relies on air conditioning to get air circulation. Two other families sat at a table next to him with a table spacing of about one meter.
The patient first has a fever and cough the next day and then goes to the hospital. Within two weeks, four other family members, three family members at another table and two family members from another table were infected with the corona virus.
“From the results of examining potential transmission routes, we conclude that the most likely cause is droplet transmission. We conclude that this outbreak, droplet transmission is supported by AC. The key factor of infection is the direction of air flow,” the researchers said in their report quoting from the South China Morning Post.
However, researchers realize the findings are less consistent with aerosol transmission. However, they continued, aerosols tend to follow air flow and lower aerosol concentrations at longer distances may not be enough to cause infection in other parts of the restaurant.
“To prevent the spread of the virus in restaurants, we recommend increasing the distance between tables and providing ventilation,” they added.
