The US Centers for Disease Control and Prevention (CDC) has warned of an increase in stomach virus outbreaks on cruise ships. The figure is alarming since it exceeds the number of waves for 10 years, in total there have been 13 so far this year.

According to the CDC, norovirus is highly infectious and is often labeled a stomach virus. It is usually the most common cause of nausea, vomiting, diarrhea and stomach pain. People are infected through contaminated water or food, it can also be acquired by touching a contaminated surface.

That is why they recommend washing your hands continuously, disinfecting surfaces with bleach, cooking more carefully by handling food correctly, and washing clothes with hot water. These recommendations would help prevent the spread of norovirus.

Outbreaks are reported by the CDC when they exceed 2% or more of the passengers, also when the crew reports symptoms of gastrointestinal illness to the ship’s medical staff.

In turn, cruise ships must notify the disease after 15 days upon arrival at a port in the United States. They must comply with the characteristic of carrying more than 100 passengers on board and sailing between three and 21 days, to report the outbreak.
