Hantavirus Dangerous for Infected, but Transmission Risk Extremely Low — WHO

The World Health Organization (WHO) has moved to quell public anxiety regarding a hantavirus outbreak on the cruise ship Hondius, asserting that the risk of transmission to the wider population remains 'absolutely low' and bears no resemblance to the COVID-19 pandemic. This clarification comes after three deaths and several illnesses aboard the vessel sparked significant international attention.

The risk of hantavirus spreading among the general public remains 'absolutely low,' and the situation has nothing to do with the COVID-19 pandemic.

WHO representative Christian Lindmeier detailed that even individuals in close contact with the infected, including a flight attendant who attended to a passenger who later died, tested negative. This reinforces the organization's assessment that the virus poses a danger primarily to those directly infected, rather than posing a significant threat to the general public. Eight cases have been registered in total: five confirmed in laboratories and three suspected.

Lindmeier further highlighted the limited human-to-human transmission capability of hantaviruses, noting that even sharing a cabin did not always lead to infection. Contact tracing is ongoing for potentially infected individuals beyond the ship. The WHO is meticulously analyzing passenger manifests and travel routes to rule out any possible transmission chains.

This confirms that the virus is dangerous primarily for those who are actually infected, but does not pose a significant threat to the population as a whole.

Crucially, the WHO distinguishes this outbreak from the COVID-19 pandemic, which claimed millions of lives. Hantavirus transmission typically necessitates prolonged and close contact, often within families, partners, or healthcare settings. The fact that the wife of an infected patient undergoing treatment in Switzerland shows no symptoms further supports the WHO's conclusion about the virus's low contagiousness. Hantaviruses are zoonotic, carried by rodents, with human infection usually occurring through contact with infected animals or their excreta. The Andino strain, found in parts of Latin America, is the only known hantavirus capable of limited human-to-human transmission, and it is believed to be responsible for the infections on the Hondius.
