Many people still seem to think that it is transmitted on surfaces. Not instead of airborne, but additionally.
And I don't mean experts or lawmakers (that I know of), I mean in my area of the US, grocery stores and gas stations (sometimes) have signs saying put a plastic bag or gloves on your hands.
- GeekyBear 5y agoThe initial advice was all based on the theory that Covid had a droplet based spread: Wear a cloth mask to catch large droplets before they spread. Stay six feet apart, because large droplets fall to the ground within that distance. Use hand sanitizer and disinfect surfaces droplets might fall on. Put up sneeze guards at registers to protect the cashiers. However, once you know the virus is fully airborne, you can focus on different things, like improving indoor ventilation in public spaces so you are constantly exchanging inside air for outside air. We have HVAC systems that will help recover the ac/heat when you do this.
