LAS VEGAS (AP) - Health officials say a norovirus may be the cause of an outbreak that has affected dozens of players, coaches and parents taking part in a youth football tournament in Las Vegas.
Southern Nevada Health District spokesman Jorge Viote (hoar-hay vee-oh-tay) says his agency is interviewing the sick and taking samples from them as part of an investigation to pinpoint the cause of the outbreak.
But he says the flu-like symptoms of vomiting and diarrhea are consistent with cases of norovirus, a mostly food- or water-borne illness.
He was unsure how many people have fallen ill, but KSNV-TV in Las Vegas reports about 100 people have developed flu-like symptoms.
Tournament spokesman Justin Gates told the station that at least nine of 100 teams participating in the National Youth Football Championships have been affected. The four-day tournament ends Saturday.
He didn't immediately return phone calls to The Associated Press on Saturday.
