Approximately 100 individuals have developed flu-like symptoms, which include diarrhea and vomiting. The victims were brought to the hospital to receive treatment and medication. The symptoms reported were likely caused by norovirus

According to the spokesperson of the Southern Nevada Health District, Jorge Viote, the outbreak is still being looked into. Thus, the real reason of such outbreak is still vague as of the moment. Samples are being taken from the affected individuals to help the health officials identify and pin down the root cause of the epidemic.

"We are advising people to clean and wash their hands," said Viote when interviewed by The Associated Press. "They should take other precautions, otherwise the illness will spread," he added.

Roughly 50 players from Santa Monica and 25 players from Bakersfield were unfortunate to have developed the said illness.
