Some activities are a lot safer than others when it comes to Covid transmission risk., according to research published by ACS Publications.
In the study, both how the virus is transmitted and where this transmission is most likely are examined.Coronavirus spreads mainly by airborne transmission which means the keys to understanding how we actually become infected are actaully physics and chemistry.
Air is a fluid made up of invisible, rapidly and randomly moving molecules, so airborne particles disperse over time indoors, such as in a room or on a bus.
An infected person may exhale particles containing the virus, and the closer you are to them, the more likely you are to inhale some virus-containing particles with the risk increasing the longer you spend near that person.
