"The most important routes of coronavirus spreading are air-droplet and aerosol. Prof. A. Ambrozaitis agrees that these routes are similar, but emphasizes that aerosols are like an invisible shower. Aerosols can hang in the air for several hours. Both experts, Prof. A "Ambrozaitis and Prof. S. Čaplinskas agree that it is very important to ventilate the premises. It is also important to remember that more aerosols and droplets are released when a person screams, sings, coughs or sneezes. So experts recommend refraining from screaming or singing."
The only way to seriously protect yourself from the virus is to spare no money for heating, constantly ventilating the premises at work and at home, and diligently use the best masks possible.
