[[Currently, the United States is only conducting health screenings for passengers who are flying in from China.]]
And many states are only requiring voluntary isolation- there are 1000’s of people in cities all across the country who have traveled to china who are not under isolation, and are just being asked to voluntarily isolate themselves if they feel sick— and when people get off a plane, they could be in the very beginning of the virus, and not show any symptoms at all- then days later, while at home, or at work, they begin coughing, hacking, throwing up etc-
Why can’t the State of NY do the screening?
