How does Coronavirus spread?
According to the CDC: The virus that causes COVID-19 is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet).
We ourselves unwillingly can be carriers of Viruses and Bacteria. Germs present on other objects and surfaces can quickly transfer to our shoes, money, clothes, jewelry, watches, toys, utensils and other necessities.
CDC: Therefore, the soles of medical staff shoes might function as carriers. The 3 weak positive results from the floor of dressing room 4 might also arise from these carriers. We highly recommend that persons disinfect shoe soles before walking out of wards containing COVID-19 patients.
