"The Los Angeles County Public Health Department said in a statement that it appears there is no threat to public health, cautioning, "People should not be excluded from activities based on their race, country of origin, or recent travel if they do not have symptoms of respiratory illness."

This seems totally insane to me, and a symptom of our "don't offend anyone!" culture.
I'm in total agreement with not excluding anyone based on their race or country of origin - that's just basic human decency, not to mention common sense since neither trait has anything to do with contracting coronavirus - but if you recently traveled anywhere near Wuhan, China, I'm not getting anywhere near you right now. I'm not an infectious disease expert, but to me it sure seems dangerous to assume that all asymptomatic folks who may have traveled near the danger zone are safe to interact with.
