As we all surely know, the best way to prevent illness is to avoid being exposed to harmful pathogens. Viruses, such COVID-19, are mainly spread from person-to-person. Typically, between people who are in close contact with one another. Through respiratory droplets produced when an infected person coughs, sneezes or even talks. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Transmission of coronavirus occurs much more commonly through respiratory droplets than through objects and surfaces, like doorknobs, countertops, keyboards, toys, etc. Current evidence suggests that SARS-CoV-2 may remain viable for hours to days on surfaces made from a variety of materials. Cleaning of visibly dirty surfaces followed by disinfection is a best practice measure for prevention of COVID-19 and other viral respiratory illnesses in households and community settings.
Some recent studies have suggested that COVID-19 may be spread by people who are not even showing symptoms. So even if you don’t feel sick it is important to wear a mask when in public spaces. It’s unknown how long the air inside a room occupied by someone with confirmed COVID-19 remains potentially infectious. Clean AND disinfect frequently touched surfaces such as tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, and faucets.
