Science and Technology Daily (Reporter Liu Xia ) According to a recent report on the official website of the University of Cambridge in the UK, scientists from the University of Cambridge, Imperial College and the University of Leeds have developed a model for predicting the risk of infection of the new crown virus in offices and schools.
Liu Xia The model shows that employees working in a well-ventilated, quiet office are less likely to infect each other through airborne particles, but if the room is poorly ventilated or employees participate in activities that require a lot of speech, the risk of infection increases
The model also shows that halving office usage can reduce the risk of airborne transmission by a factor of four
The researchers explained that in areas with low ventilation rates and high occupancy rates, the CO2 concentration is high, so monitoring the CO2 concentration can issue warnings to building managers to determine where the risk of spreading the new crown virus is higher, and then take appropriate measures.
One of the research leaders, Professor Paul Linden from the Department of Applied Mathematics and Theoretical Physics of the University of Cambridge, said: “Because the airflow is invisible to human eyes, it is difficult to understand the impact of the new coronavirus at home or in the workplace
