Nature.com: Touching contaminated surfaces is no longer considered to be a 'primary' factor in the spread of coronavirus. (Because surface spread IS possible, however, we are still advised to follow proper hand washing procedures and avoid touching our face. )
Research now strongly suggests that the primary way people become infected is from exposure to airborne droplets and particles emitted from the mouth or nose of someone else who is carrying the virus. This means that an emphasis on social distancing, covering our coughs and sneezes and wearing approved masks deserve even stronger attention.
Every time an infected person coughs, sneezes, yawns, speaks or simply breathes, they emit respiratory droplets. And if those droplets are infected with coronavirus and get inhaled by others, everyone nearby may become infected.
If, however, the droplets merely fall to the ground or land on surfaces such as store shelves, an ATM machine, money, door handles, bathroom fixtures, counters, grocery carts, etc. those surfaces are now contaminated
Anyone who touches those contaminated surfaces -- and then touches their eyes, nose or mouth may become infected.
How long can the virus live on surfaces?
It appears that the coronavirus that lands on surfaces may remain active for hours or days, depending on factors such as the surface material, air circulation, temperature, sunlight, amount of virus, etc.!
Fortunately, this cycle can be broken is if the virus-contaminated surfaces are cleaned with alcohol, bleach or other approved sanitizers and cleaning products.
