While this measure is an important step to reduce the risk of transmission, a new study also drills home the importance of avoiding touching your nose and mouth.
Why is it so important to avoid hand to face contact?
Every time people touch their mouth or nose, they transfer bacteria and viruses between their face and their hands.
In fact, touching your nose and mouth can cancel out the benefits of washing your hands regularly, according to a study published in the journal Clinical Infectious Diseases.
“There are many opportunities in between hand-washing episodes for people to re-contaminate their hands,” explained study researcher Dr. Wladimir Alonso, a global health researcher at the National Institutes of Health in Bethesda, Md.
To investigate the impact of this action, Alonso and colleagues randomly selected 249 people in public places, on the Washington, D.C. subway and in the Brazilian city of Florianopolis.
The researchers observed them, noting how often they touched a common surface and then their mouth or nose.
They found that people touched their faces an average of 3.6 times per hour, and common objects an average of 3.3 times per hour.
This rate of self-touching means that people will likely get germs on their hands much more frequently than they wash germs off their hands, according to the study.

“It is important to understand the basic mechanisms through which diseases are transmitted to take full advantage,” of hand-washing, Alonso said.

Coronavirus – what we know so far
Coronaviruses (CoV) are a large family of viruses that cause illnesses ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).
A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people.
Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans.
Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties.
In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
