SARS-CoV2, otherwise known as the Coronavirus, is a new virus - meaning that human beings have not previously been exposed to it.
It is a virus that is related those that cause the common cold, but since human beings have not been exposed to it in the past, our immune systems aren’t as effective at controlling its spread right now.
How does the coronavirus spread?
The virus is spread through droplets from an infected person. Droplets are essentially tiny bits of liquid that people expel when they cough, sneeze, or exhale.
There are two ways to get infected from these droplets. A person can breathe them in directly, which is why we recommend you maintain at least 1 meter’s distance from anyone who is coughing, sneezing, or appears unwell. Even if you don’t breathe the droplets in directly, these droplets can carry the virus and live on various surfaces for a period of time (hours to days).
When a person touches a surface that contains active droplets, the virus gets on that person’s hands. From there, people habitually tend to touch their faces, which is how the virus typically can enter the body. That is why hand washing is so important and can be so effective. It is also why wearing a mask is so important. If you are infected but are wearing a mask, the likely you will infect others is far lower than if you are not wearing a mask.
