Coughs and sneezes undoubtedly spread disease, but when it comes to coronavirus, doorknobs, touchscreens, and public shared touchpoints pose a big risk of infection.
Corona Virus survives on many public surfaces for hours to several days with no way of knowing how many or how often infected or asymptomatic people have been in contact.
Very hard to break the habit of touching your face ( average is 23 times a day or more) especially during the stressful times of living in a Pandemic where there is a higher risk of inadvertently transferring coronavirus through the mouth, eyes or nose as social distancing regulations and stay-at-home orders begin to relax.
For a few dollars you can be assured of integrating back into daily life under the Coronavirus New Normal without constantly worrying if you just touched an infected surface or gave yourself coronavirus.
