In Australia, vials containing an extremely dangerous hantavirus disappeared without a trace from one of the laboratories approximately five years ago. However, the disappearance was only discovered much later — in August 2023. Despite investigations, the location of the missing samples remains unknown.
The situation raises additional concerns in light of a recent incident: an outbreak of illness, presumably linked to hantavirus, occurred on board the cruise ship Hondius. As a result, three people died, and another 149 passengers, according to the investigation, may have been infected and dispersed across different countries around the world, which potentially complicates efforts to control the spread of the infection.
Hantaviruses are a group of dangerous pathogens that are most commonly transmitted to humans through contact with infected rodents or their excretions. In some cases, they can cause severe lung damage and hemorrhagic fevers with a high fatality rate. That is why any incidents involving the loss or leakage of laboratory samples are considered a potential biological threat.
Biosafety experts note that even isolated breaches in the storage of dangerous strains can have global consequences, especially in conditions of high population mobility and international travel.
