On a cruise ship in the US, about 100 people fell ill with stomach and intestinal disorders among passengers. The US Centers for Disease Control and Prevention (CDC) launched an investigation into the incident.

According to CDC data, nearly 100 people fell ill due to an outbreak of gastrointestinal illness on board the Royal Caribbean ship. Passengers sought medical attention with complaints of nausea, vomiting, diarrhea and abdominal pain. The CDC is investigating whether the outbreak was caused by a contagious virus such as norovirus. According to CruiseMapper, the ship departed from Tampa, Florida, on February 1 on a seven-day cruise with stops in Mexico, Honduras and Belize.

Royal Caribbean officials said they have increased cleaning and disinfection measures on board to prevent the spread of the outbreak. Passengers were warned to pay attention to hand hygiene.
