Cruise expert Professor Ross Klein reports that the Centers for Disease Control (CDC) indicates that 307 of 2112 passengers (14.5%) and 14 of 952 crew (1.5%) aboard the Celebrity Summit have reported sick with "gastrointestinal illness."

You can read about the outbreak on the CDC website here.

There is no indication whether the illness is due to norovirus, e-coli or some other virus or bacteria. 

The CDC is working with Health Canada officials as the cruise ship sails in Canada on its way to Bayonne, New Jersey,  The cruise ship will arrival in Bayonne on October 5, 2013.

The CDC will send an epidemiologist and an environmental health officer to meet the ship and conduct an epidemiologic investigation and environmental health assessment, and monitor the sanitation procedures onboard prior to the embarkation of new passengers.

Over 14% of the passengers being sick with gastrointestinal illness is a very high percentage.  

In the past week, we have reported about cruise ship norovirus outbreaks on two Fred Olsen cruise ships, the Black Watch and the Boudicca.
