'During the sailing, we took a number of steps to prevent the transmission of the illness, including implementing enhanced cleaning procedures and protocols, and using special cleaning products and disinfectants that are proven to kill norovirus to clean throughout the ship. 'Additionally, when Celebrity Infinity arrived to San Diego, California, today, we began an extensive and thorough sanitizing onboard the ship and within the cruise terminal, to help prevent any illness from affecting the subsequent sailing.' The statement continued 'Also, all guests will receive a letter at boarding that asks if they have experienced any gastrointestinal symptoms within the last three days. Similarly, if any guest is uncomfortable taking their cruise, for reasons related to personal health or otherwise, our staff assisted them in rescheduling their sailing for another time.' The Maritime-Executive reported the ship previously experienced gastrointestinal illness outbreaks in 2006 and 2013.
