World Health Organization officials said Thursday that a hantavirus outbreak on the cruise ship MV Hondius is not the start of a pandemic [1].
The announcement aims to calm global fears that the cluster of cases in the Atlantic Ocean could mirror the rapid spread of SARS-CoV-2. Because hantavirus behaves differently than the virus that caused Covid-19, health officials said the risk of a global health emergency is minimal [1, 3].
Director-General Tedros Adhanom Ghebreyesus said the wider public health threat from the outbreak linked to the vessel remains low [1]. The WHO briefing included Abdirahman Mahamud, head of health emergency alert and response operations, and epidemiology lead Maria Van Kerkhove [1, 2].
Van Kerkhove said hantavirus transmits poorly between people, which makes it unlikely to become the next pandemic [3]. This biological characteristic distinguishes the virus from more contagious respiratory pathogens that spread easily through human contact.
Despite the low risk of a pandemic, officials are monitoring the situation closely. Mahamud said a large epidemic is not anticipated, though more cases may emerge due to the long incubation period [2]. The WHO said that the incubation period for hantavirus can last up to two weeks [2].
Emergency responses have already begun for those affected on the ship. Two Britons were medically evacuated from the MV Hondius to receive hospital care [4].
WHO officials said that while the situation on the cruise ship requires attention, it does not signal a systemic threat to global health security [1, 2].
“"The wider public health threat from the hantavirus outbreak linked to the cruise ship MV Hondius remains low."”
The WHO's rapid clarification underscores the sensitivity of global health monitoring in the post-Covid era. By highlighting the specific transmission limitations of hantavirus, namely its inability to spread efficiently between humans, the organization is attempting to prevent public panic and avoid the economic disruptions that typically accompany pandemic scares.
