Why is handwashing so important in preventing infections?

Handwashing with soap removes germs from hands. This helps prevent infections because: People frequently touch their eyes, nose, and mouth without even realizing it. Germs can get into the body through the eyes, nose and mouth and make us sick. Germs from unwashed hands can be transferred to other objects, like handrails, table tops, or toys, and then transferred to another person’s hands. – cdc.gov

What is meant by the “T-Zone” in medical terms?

The T-zone — eyes, nose and mouth — is the main portal of entry for viral infections such as influenza, colds and pneumonia, as well as bacterial infections including strep

throat, tuberculosis or tonsillitis. – ucihealth.org

Face touching: a frequent habit that has implications for hand hygiene

Results: On average, each of the 26 observed medical students touched their face 23 times per hour. Of all face touches, 44% (1,024/2,346) involved contact with a mucous membrane, whereas 56% (1,322/2,346) of contacts involved nonmucosal areas. Of mucous membrane touches observed, 36% (372) involved the mouth, 31% (318) involved the nose, 27% (273) involved the eyes, and 6% (61) were a combination of these regions. – National Center for Biotechnology Information

What is coronavirus?

Corona viruses are an extremely common cause of colds and other upper respiratory infections. – Harvard Medical School

What is a novel coronavirus?

A novel coronavirus is a new coronavirus that has not been previously identified. The virus causing coronavirus disease 2019 (COVID-19), is not the same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold. – cdc.gov

There is still a lot that is unknown about COVID-19 and how it spreads…

Coronaviruses are thought to be spread most often by respiratory droplets. Although the virus can survive for a short period on some surfaces, it is unlikely to be spread from domestic or international mail, products or packaging. However, it may be possible that people can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.cdc.gov
