There is no such thing as an aerogel, the question should refer to aerosols. Aerosols can transmit novel coronaviruses. Aerosols are solid and liquid particles suspended in gas, and liquid particles with a diameter of 0.001 to 100 microns can float in the atmosphere for a long period of time, so they can easily spread coronaviruses. If a virus carrier leaves a large amount of virus in a poorly ventilated confined space, and the virus remains in the air for a short period of time, then susceptible people who enter the space afterward may inhale the airborne virus, which can lead to the spread of the virus. You should do good ventilation on a daily basis, keep a distance of 2m between outdoors and others, and wash your hands and wear a mask diligently to prevent aerosolized coronavirus infection.
