Hundreds of passengers fell sick aboard a Royal Caribbean cruise this week due to a gastrointestinal illness — a common issue that plagues cruise lines due to close living quarters, among other factors.
The five-night cruise docked in Florida on Saturday as 332 passengers contracted a stomach-related illness, a spokesperson for Royal Caribbean told CNN. Owen Torres, the spokesperson, noted that was a small percentage of the 5,547 passengers on board, and that cruise ship doctors gave those with the illness over-the-counter medicine.
A representative for Royal Caribbean did not respond immediately to a request for comment from TIME.
Meanwhile, hundreds of other passengers aboard another Royal Caribbean cruise recently also fell ill, according to NBC News. Of 5,796 passengers on board that ship, 209 people grew ill — five of whom were treated at an Australian hospital upon reaching land, according NBC News. That 14-night cruise docked in Sydney on Dec. 7.
When a Twitter user who had booked a Royal Caribbean cruise for the upcoming week expressed concern about the recent outbreaks, a representative for the cruise line said “we’re taking all necessary precautions onboard to assure everyone’s safety.”
