All of those so called experts are just reacting to the Novel Covid-19 virus as it plays out in real time. We are in a Horror Movie where the plot is unknown and that is why this is so concerning.
Remember 2 months ago when all of the experts said to people " do not wear a mask" Now wearing a mask has become the "norm".
It is common sense that a very contagious virus can spread via surface contact, albeit not as much via air droplets. That still calls for proven disinfectant protocols.
IMO, we are just one news story away from a big run.
