Universities all over the world are scrambling to assess the risks to their programs from China's virus outbreak.
Some are canceling study-abroad opportunities and prohibiting travel affecting hundreds of thousands of students.
In the U.S., the cancellations add to the tension between two governments whose relations were already sour.
The scare also threatens to cause lasting damage to growing academic exchange programs that reached new heights over the last decade and a half.
China sends far more students to the U.S. than any other country, more than 369,000 in the last academic year. The U.S. sends over 11,000 students to China annually.
