If you know of any rural Italian 80 year olds and bed ridden American seniors vacationing in China, kindly let us know.
None of these people have been in contact with foreign travelers, yet they still got infected.
Its not always a one on one simple transmission thing, because if it was, stopping it would be a lot easier.
Rural Italians and bedridden nursing home patients could have been visited by vacationing relatives and friends or cared for by infected persons returning from their vacations overseas. Nursing home patients are dependent on their caregivers. The caregivers and visitors bring the virus into the at risk population. The returning vacationing caregivers and visitors are the vectors bringing it home to the innocents.
Earlier artical on “Italians love their grandparents”. Three generations living together in close proximity. Trump closed flights from China in January, Canada not until this week. Chinese flew to Vancouver for two months, then drove over the border into Seattle.
Surely you know your question protecting China, “How many 80 year olds do you know who have vacationed in China?” is empty...
this spreads between people, not every infected person has to go to China.
