The NCAA Men’s Swimming Championships will finally get underway today in Columbus, Ohio, after a one-day delay due to the highly contagious Norovirus, according to The Columbus Dispatch. The Ohio Department of Health lab confirmed the Norovirus as the cause of at least 19 cases of illness late Thursday night after taking samples from four individuals.

The Championships will begin today at noon at McCorkle Aquatic Pavilion on the campus of Ohio State University.

Arizona, Stanford and Texas have contracted the virus, and nine athletes alone were hospitalized from the Arizona team. The program would not release the names of the specific individuals, but confirmed that all nine have been released from the hospital according to Arizona head coach Frank Busch.

The Norovirus is spread through the air and can cause stomach pain, diarrhea and vomiting. Those who were infected were advised to stay out of the pool for 48 hours until after they stopped showing symptoms of the virus.

Although all three programs took the same American Airlines flight from Dallas/Fort Worth International Airport according to Jen House, spokeswoman for the state of Health Department, public health officials aren’t ruling anything out at this point.

“”It’s also possible they were exposed to something here in Columbus and we’re concerned about that,”” Columbus medical director Dr. Mysheika LeMaile-Williams told The Columbus Dispatch.

The championships were pushed back after a coaches meeting late Wednesday and the Centers for Disease Control and Prevention expressed concern over the possibility of infected swimmers using the pool.

“”We are going to try to do our best to try and weather the storm,”” Busch said on Wednesday.
