Hantavirus Outbreak: Cruise Ship Evacuated Due to Health Concerns for US Passengers
A serious hantavirus outbreak aboard a Dutch cruise ship has led to a global health emergency declaration. Tragically, three passengers have died, and about 150 individuals were evacuated to the Canary Islands. There are currently 17 Americans under observation as they return to the U.S. Interestingly, the World Health Organization (WHO) has noted that the Andes strain of the virus is not easily transmitted between humans, unlike COVID-19, and the Centers for Disease Control and Prevention (CDC) has rated it a Level 3 emergency.
In another cruise-related health development, over 100 passengers on the Caribbean Princess ship have been affected by a recent norovirus outbreak, as reported by the CDC. Specifically, 102 out of 3,116 passengers (about 3.3%) and 13 out of 1,131 crew members (1.2%) have reported symptoms such as diarrhea and vomiting. This situation was first reported to the CDC on May 7.
The voyage in question took place from April 28 to May 11. Princess Cruises indicated that a limited number of individuals experienced mild gastrointestinal issues during the trip.
“We can confirm that a few individuals reported mild gastrointestinal illness during the Caribbean voyage that set sail from Port Everglades on April 28,” a spokesperson said. They also mentioned that measures were taken to disinfect the ship during the voyage, with comprehensive cleaning planned once it reaches Port Canaveral on May 11.
In response to the outbreak, Princess Cruises has adopted enhanced cleaning protocols and collaborated with the CDC to ensure proper hygiene and case reporting. They’ve also collected stool samples for further testing and isolated sick passengers and crew members.
According to the CDC, an on-site response is active, involving an environmental assessment and investigation to curb the spread of the virus. Notably, Stewart Chiron, a cruise industry expert, pointed out that while norovirus cases are prevalent in the U.S. (with millions reported annually), the percentage occurring on cruise ships remains relatively small.
He explained that outbreaks often begin when infected passengers board the ship and unknowingly spread the virus. However, cruise lines are taking strict hygiene measures, quickly isolating those who show symptoms to prevent wider transmission. Interestingly, the number of cases reported on the Caribbean Princess slightly surpassed the CDC’s outbreak threshold of 3%.
Norovirus is recognized as a common cause of gastrointestinal illness on cruise ships. The CDC emphasizes that the reported cases reflect illnesses over the course of the journey and do not imply that all passengers became sick simultaneously.
