University of Michigan officials are investigating a rash of student illnesses according to a report from the Michigan Daily.

Students took to social media to share symptoms and quickly realized that their experiences may have been related. Speculation on Twitter and anonymous social media app Yik Yak centered around the dining hall at the South Quad dormitory.

Dr. Robert Winfield, executive director of University Health Services, told the Michigan Daily that approximately 20 to 25 students had been seen in the emergency room and health services clinic with symptoms that include vomiting and diarrhea. The school is working with the county's health department to diagnose the illness and believe norovirus could be the cause. Testing for the disease takes approximately five days to complete.

The illness could delay the start of the Women's Big Ten Swimming and Diving Tournament, which was scheduled to begin Wednesday at 6:30 p.m.

"The University of Michigan campus has been notified of an illness linked to several community members, including members of the Michigan women's swimming & diving program," spokesman Brad Rudner said in a statement.

"With the Big Ten Women's Swimming & Diving Championships held in Ann Arbor this week, the Big Ten Conference, University of Michigan athletic department and University of Michigan Health System are monitoring the situation throughout the day to assure Canham Natatorium is a safe environment for all competitors and spectators."
