## WHO Investigates Possible Rare Hantavirus Human-to-Human Transmission on Cruise Ship Following Fatalities
**GENEVA –** The World Health Organization (WHO) has launched an urgent investigation into the potential human-to-human transmission of Hantavirus on a cruise ship, an event considered exceptionally rare for the virus. The inquiry follows the confirmation of two cases aboard the vessel, with three associated fatalities reported.
Hantavirus is predominantly transmitted to humans through direct contact with infected rodents, their urine, droppings, or saliva, or by inhaling aerosolized particles from these sources. Human-to-human transmission is considered exceedingly rare, making this potential cluster of cases on a cruise ship a serious focus for global health authorities.
Hantaviruses are a group of viruses primarily carried by rodents, capable of causing severe and potentially fatal diseases in humans, such as Hantavirus Pulmonary Syndrome (HPS) and Hemorrhagic Fever with Renal Syndrome (HFRS). Initial symptoms often include fever, muscle aches, and fatigue, which can progress rapidly to severe respiratory distress or kidney failure, often weeks after initial exposure.
In response, the WHO, alongside relevant national public health agencies, is coordinating a comprehensive contact tracing operation. This aims to identify all individuals who may have been exposed on board the vessel and to monitor their health status. Passengers and crew who were aboard the affected cruise during the relevant period are being urged to remain vigilant for symptoms and to seek immediate medical attention if they develop any concerning signs.
While the overall risk of Hantavirus for the general public remains low given its primary mode of transmission, this incident highlights the critical importance of robust public health surveillance and rapid response protocols in enclosed, high-traffic environments like cruise ships. Investigations are ongoing to determine the exact circumstances of transmission and to reinforce preventative strategies.
