An outbreak of hantavirus aboard a cruise ship has raised concerns and triggered memories of COVID-19 for some individuals, although health officials emphasize that the risks are minimal. Dr. Heather Morrison, the chief public health officer of Prince Edward Island, reassured the public that hantavirus does not pose the same threat of a pandemic as COVID-19 due to its limited transmission capabilities.
Hantavirus is primarily transmitted through exposure to rodent feces, urine, and saliva that become airborne and are inhaled. Unlike COVID-19, hantavirus does not easily spread between individuals. The virus has an incubation period ranging from one to five weeks.
The recent hantavirus outbreak occurred over a three-week period on the cruise ship MV Hondius, which departed from Ushuaia, Argentina, with 175 passengers and crew on board. Tragically, a 70-year-old Dutch man passed away on April 11 while on the ship. The World Health Organization responded to the suspected hantavirus outbreak when the ship was located near Cape Verde in early May.
As of the latest update, seven cases of hantavirus have been confirmed by the WHO, and all passengers, along with some crew members, have disembarked from the MV Hondius, currently docked in the Canary Islands. Four Canadian passengers who landed in Victoria have shown no symptoms but will undergo a 21-day isolation period in British Columbia as a precaution.
Although three fatalities have been reported since the outbreak began, health officials stress that the risk of further transmission is low. Dr. Morrison emphasized that Prince Edward Island has not recorded any hantavirus cases and highlighted the importance of closely monitoring individuals who may have been exposed to the virus.
Symptoms of hantavirus infection are similar to those of influenza, including headache, fever, muscle aches, and cough, with respiratory distress developing in later stages. Dr. Morrison expressed concern for those who had contact with infected individuals and reassured the public that while vigilance is necessary, hantavirus is not poised to spark another pandemic akin to COVID-19.
