PYEONGCHANG, South Korea – The organizing committee for the Pyeongchang Olympics has called in 900 military personnel after more than 1,200 security workers were pulled off duty because of concerns about the spread of the Norovirus, Christophe Dubi, IOC executive director of the Olympic Games said Tuesday.

Later Tuesday evening, the organizing committee said 32 cases of Norovirus had been confirmed and those people were quarantined after being treated. Those 32 cases involve 21 private security staff members from the Horeb Youth Center and 11 people from other locations, including three foreigners.

In a statement, POCOG said that starting Sunday workers reported headaches, stomach pain and diarrhea. The Gangwon Province Health and Environment Research Center found  41 workers with symptoms that might be related to the virus. The others have been pulled from duty to prevent possible spreading of the illness.

The workers are largely responsible for checking credentials and screening baggage entering the venues. The military personnel were brought in from about 40 minutes away.
