Question

Q12. COVID-19 virus can spread when an infected person coughs or sneezes and releases these droplets into the air, where they are either inhaled by others, or can land on other people’s mouths or noses if they’re near enough- generally a distance of about six feet (1.8 meters). Once the virus finds itself inside a new human host, it can start infecting cells and cause disease.
Since the disease spreads via respiratory droplets, neither a handshake or fist bump would be a primary way to pass along the virus. An infected person would have to sneeze or cough into his hand, touch someone else’s hand, and that second person would then have to place that hand in close contact with their nose, mouth or even eyes to get infected with any virus that might still be on the hand’s surface. Throughout any given workday, employees use their hands to write up a report, shake hands with a new client, open doors and much more. All of these activities expose hands to harmful germs and bacteria.
According to the World Health Organization (WHO), hand sanitizer is one of the best tools available to avoid spreading virus. Hand sanitizer is a
