The World Health Organization said the risk of hantavirus spreading to the wider public is low following a suspected outbreak on a cruise ship.
The assessment comes as health officials manage the aftermath of an outbreak in a confined maritime environment, where the potential for human-to-human transmission is closely monitored.
The incident occurred on the MV Hondius [5], which was anchored off the coast of Cape Verde in the Atlantic Ocean. On Monday, officials coordinated the evacuation of about 150 people [3] from the vessel.
According to the WHO, only two confirmed cases of hantavirus were identified on the ship [1]. Despite the low number of confirmed infections, the outbreak resulted in three deaths among the passengers [2].
Among those on board were four Canadian nationals [4]. The WHO said that hantavirus rarely spreads between humans, which contributed to the determination that the general public remains at low risk.
Authorities have focused on the specific conditions of the MV Hondius to determine how the virus was introduced. Because the virus typically spreads through contact with infected rodents, the concentrated environment of a ship can complicate containment efforts, though the WHO maintains the threat is limited.
“The risk of hantavirus spreading to the wider public is low”
This incident highlights the volatility of zoonotic diseases in the cruise industry, where high passenger density can accelerate the spread of illness. While the WHO's low-risk assessment is based on the virus's typical inability to transmit between humans, the disparity between two confirmed cases and three deaths suggests a high fatality rate among those infected or the presence of other complicating health factors.
