This is BY FAR the best article on coronavirus. You can skip the rest.

Pretty good article, except for one glaring omission (error?); nobody anywhere has any accurate idea of the number of cases or the death rate. Children are the primary vector for essentially all respiratory infections, and children only get a mild cold from this virus, if they get sick at all. Even young adults are likely to have mild or sometimes no symptoms, and both of these groups are 1) uncounted cases and 2) contagious. Older adults, especially with chronic illnesses, are hard hit; the latest figures from Italy suggest that about 90% of their many fatalities are in people over 70.
One suggestion is absolutely correct; the virus is almost certainly everywhere in the US. Every large city, every state. What will happen next is anyone's guess.
