From Virus to Protection #8: Transfer -Infection by Picking Up a Virus off Contaminated Surfaces
A blog series on SARS-CoV-2 (the virus that causes COVID-19) and how spread can be eliminated.
This blog series was inspired by the many questions people ask on this topic (see our FAQ links for more)
NOTE: Infection through direct contact with contaminated surfaces was thought to be the primary cause of infection, but with more recent evaluation of studies and consultation with experts, it is now believed that the airborne pathway is the most prevalent cause of infection.
As a refresher, here is what was presented earlier:
The pathway of infection starts with bodily fluids from an infected person’s cough, sneeze, or breath being sent on a journey. The route it takes could be from a contaminated surface that you touch before touching your eyes, nose, or mouth. This gives the virus passage to your bodily fluids where the virus begins to breed.
It’s important to remember that an infected person will continuously contaminate their surroundings to whatever extent they are not keeping their bodily fluids to themselves. Wherever they go, they create more and more fomites (objects contaminated with virus particles, including people’s clothing and skin).
But that’s not all. Just one person can contaminate an area, but others can spread that contamination around the community even without becoming infected themselves.
For instance, someone without a face covering behind you in a checkout line at the store sneezes on you, and when you get home just 10 minutes later your wife welcomes you home, hugs you from behind, touches her mouth maybe on your hair or the back of your ear …and now she is infected.
Becoming infected from fomites is an indirect pathway, and although thought to be rare, it is still a true pathway of infection that should not be ignored.
The virus spreads unless bodily fluids are contained, and the virus is killed or disposed of properly. It’s possible that one person can infect may people without anyone knowing it.
For this reason, hand cleaning and other surface cleaning is still recommended to be done properly, and often -whenever there has been a potential exposure.
Disclaimer: We make no claim that these teachings are up-to-date. Researched by a scientist, they are current understanding, to the best of our knowledge. Consult medical professionals before making medical decisions for yourself or others, just to be sure. Be safe, be careful. SARS-CoV-2 (the virus that causes COVID-19) is a serious enemy that can kill.
