Misinformation about the recent hantavirus outbreak on a cruise ship.

The recent Andes virus (ANDV) outbreak associated with the cruise ship MV Hondius generated substantial misinformation on social media. This editorial addresses six prominent myths concerning pandemic potential, airborne transmission through ventilation systems, unproven treatments, risks associated with cruise travel, influenza-like transmissibility, and claims that the outbreak was fabricated. Current evidence indicates that, although ANDV can rarely spread between people following close and prolonged contact, its transmission differs fundamentally from that of highly contagious respiratory viruses. The outbreak highlights the need for scientists, public health authorities, healthcare professionals, and the media to communicate evidence rapidly and transparently. Effective responses must control not only emerging infections but also the accompanying spread of misinformation.
