At least 150 inmates and seven guards have reportedly fallen ill at the Clark County jail in Las Vegas, Nevada after a norovirus outbreak as health authorities are currently working upon decontamination of the building. The stomach-related illness was reported Saturday, with most inmates complaining about distress such as diarrhea, vomiting and cramps.

AP reports that nearly all the infected inmates worked in the kitchen and authorities are speculating that the virus might have been spread throughout the 3,100-bed detention through the use of contaminated food or trays.

According to a statement released by the jail's health department, no one had been hospitalized and new inmates brought to the facility were being housed in an area that had been cleaned.

Following the outbreak, there were no public visiting hours at the jail on Wednesday, but inmates were allowed to meet with lawyers through glass partitions. The virus, also called Norwalk virus, is a group of related, single-stranded RNA, nonenveloped viruses that cause acute gastroenteritis in humans.

This highly contagious disease spreads from person-to-person and causes flu-like systems including nausea, vomiting and diarrhea. Experts recommend washing hands frequently to help reduce the chance of spreading the virus.
