这是高中校长给家长发的部分email，你看，他们看CDC让他们怎么做，

"Certainly, the coronavirus (COVID-19) is on everyone's minds these days.  Please be assured that @@@ High School is taking every precaution to keep your kids safe and healthy.  We are following all recommendations from the Ohio Department of Education, Center for Disease Control and the World Health Organization.  We have a number of students, teachers, and parents traveling abroad over spring break.  Again, we are monitoring the situation carefully and working with the travel companies to determine the best course of action."
