7Michael/iStock Editorial/Thinkstock(LAS VEGAS) -- The Southern Nevada Health District has identified three additional cases of measles connected to a restaurant on the Las Vegas Strip.
The cases, in adults under the age of 55, are considered to be the result of transmission from an under-immunized staff member at Emeril's New Orleans Fish House at the MGM Grand Hotel & Casino earlier in February.
The new cases are two staff members and a patron, according to health officials.
Two other cases connected to Emeril's were reported earlier in the month, according to ABC News affiliate KTNV-TV.
An under-immunized worker was diagnosed on Feb. 10, and an infant was diagnosed with measles on Feb. 11. It is believed the infant spread the illness to the worker.
One of the newly diagnosed staffers was potentially contagious while working shifts this month
The new cases bring to nine the number of confirmed measles cases in Clark County in 2015, according to health officials. These are the first confirmed cases in of measles in southern Nevada since 2011.
