All Yale University students returning to its New Haven, Connecticut, campus after winter break must quarantine until they test negative for COVID-19, the school's newspaper reported.
Students are also being instructed to avoid eating at local restaurants, even if outdoors, the Yale Daily News reported, citing an email from the school.
Students are allowed to return to campus between Jan. 14 and Feb. 4, during which time they must quarantine in their dorms until their "arrival" tests are negative. The campus-wide quarantine ends Feb. 7, the school announced on Dec. 22.
"The fall term demonstrated how effective the health and safety measures we have established are at preventing the spread of COVID-19," Yale President Peter Salovey said in the Dec. 22 announcement. "Most of the transmissions resulted from off-campus social gatherings or within households."
For meals, students have access to "grab-and-go" food from the school or may order curbside pickup — rather than eat indoors or outdoors — from local establishments, the paper reported.
"If your arrival test is negative, you may move around campus, but avoid local businesses, restaurants and bars, including outdoor dining or drinking," the email states, adding that students must follow the guidelines whether they live on or off-campus.
