NEW BRUNSWICK, N.J. – Rutgers University recently implemented a ban on student and faculty travel to Ebola-affected countries for school business and university officials as a precautionary measure.

The school implemented the ban last week for school business to Guinea, Liberia, Sierra Leone and Mali, and “strongly discouraged” personal travel to those countries, NJ.com reports.

The measure is precautionary as the school has no known scheduled trips for university business, Rutgers spokesman Greg Trevor told the news site.

Trevor said Rutgers developed the policy from recommendations in a Center for Disease Control Report and after reviewing the policies implemented by other Big Ten schools.

“Students and faculty are also banned from hosting anyone for university business within three weeks of the guest returning from those countries,” NJ.com reports.

Hosting visitors from the affected countries for personal reasons is also “strongly discouraged.”

“Students and faculty seeking an exception to the policy, including to aid with the response to the Ebola outbreak, must submit a written petition for approval from the appropriate dean and the chancellor,” according to the news site.

“Limited exceptions to these policies may be granted on a case-by-case basis, according to the university.”

Other schools have taken similar measures.

Virginai Tech announced earlier this month it’s banning students and staff from travel to Guinea, Sierra Leone and Liberia and discouraged personal travel, WDBJ7.com reports.

That school also implemented the policy as a precaution and currently has no ongoing student or staff projects in the affected countries.

Cornell, Columbia, and Harvard Universities, as well as the State University of New York and University of North Carolina implemented travel bans in October, some with exceptions for humanitarian aid that must be pre-approved, according to the New York Times.

“They must apply through the school, receive the approval of their dean, and then they must be approved by me,” John Coatsworth, Columbia University provost, told the Times. “And we will give that approval only in cases when we are certain that the travel will indeed help in containing the disease and that the traveler is well-prepared.”

The travel bans come after two Yale University students traveled to Liberia to set up a computer system to monitor Ebola. Those students were put in a voluntary quarantine for 21 days upon their return in October when one showed flu-like symptoms, CBS reports.

Ryan Boyko, a 30-year-old epidemiology graduate student from Yale, tested negative for the disease, but was ordered to stay home by state officials following his release from until the end of October, according to the news site.

“It’s been a lot of ups and downs and a whirlwind,” Boyko told CBS after the quarantine was lifted.
