The 550-member delegation was warned of the outbreak by state GOP officials in an email at 2:40 a.m. Tuesday. Schade said the virus can be lethal, if untreated.
Officials said the team members arrived in town on Thursday.
About a dozen staff members of the California Republican Party have been quarantined after an outbreak of norovirus just as the delegation touched down in Cleveland last week, multiple media outlets report. The virus is highly contagious and can spread directly or indirectly from a sick person-from shaking hands, touching shared surfaces, or through shared food items. Norovirus can spread either via person-to-person contact or through contaminated food. And it spreads quickly in closed places, such as cruise ships, schools and nursing homes, according to the Centers for Disease Control and Prevention.
The delegates are staying at the Kalahari Resort, a hotel an hour outside Cleveland, where a state party leader warned delegates to stay off the buses that shuttle delegates to the Quicken Loans Arena if they are experiencing either of the above-mentioned symptoms.
The virus, also known as a the cruise ship virus, causes abdominal pain, vomiting, fever and diarrhea. Every year an estimated 19 to 21 million people are infected with norovirus in the USA every year, according to the CDC.
In Ohio, hand sanitizer dispensers were spotted Monday night at the resort where the California delegates are staying, the Los Angeles Times reported.
The support staff helps delegates plan events and trips during the Republican National Convention being held this week in Cleveland. Usually, people recover within one to three days, though the very old and the very young are most at risk for more seriouscomplications.
