About a dozen staff members in the California delegation who are in attendance at the Republican National Convention in Cleveland have fallen ill with Norovirus, reports Washington Post.
As of Tuesday, at least 11 of the delegation's 36 staffers have shown signs of infection, according to Peter Schade, the Erie County health commissioner investigating the outbreak.
California GOP chairman Jim Brulte told Washington Post a staff member who arrived early to the convention was the first to exhibit symptoms consistent with Norovirus. The individual was reported ill July 14.
So far, no delegates or alternates from the delegation have shown symptoms, according to the article.
Norovirus can cause extreme vomiting and diarrhea and has been known to be exceedingly contagious, according to the CDC. The Ohio health department is running tests to confirm the infection is Norovirus, reports STAT News.
In the mean time, all persons exhibiting symptoms have been quarantined in their hotel rooms until health officials confirm their recovery.
