'Very negligible' risk of hantavirus in Singapore, healthcare system well-prepared: Experts

Two Singapore residents who traveled on the MV Hondius cruise ship, where hantavirus cases were confirmed, are currently isolated at the National Centre for Infectious Diseases (NCID) as of May 7. Both individuals are stable—one has a runny nose, while the other is asymptomatic—while awaiting test results for the virus. The Communicable Diseases Agency (CDA) confirmed their isolation, emphasizing that Singapore’s healthcare system is prepared to handle potential cases. Experts, including Professor Paul Tambyah from the NUS Yong Loo Lin School of Medicine, described the risk of a hantavirus outbreak in Singapore as 'very negligible.' Tambyah noted that hantavirus does not spread easily between humans unless there is close physical contact or unprotected care by healthcare workers. The two individuals are largely asymptomatic, reducing the likelihood of transmission further, as they are isolated during the incubation period. Hantavirus is primarily spread through exposure to infected rodents, particularly when inhaling dust contaminated with urine, droppings, or saliva. While the virus can cause severe respiratory and cardiac distress, human-to-human transmission is rare. Professor Hsu Li Yang, director of the Asia Centre for Health Security, echoed Tambyah’s assessment, stating that Singapore’s high hygiene standards and limited rodent exposure make infections uncommon. He added that even in confined environments like cruise ships, the risk remains low due to prompt isolation measures. The CDA clarified that transmission to humans typically occurs through direct contact with rodent carriers, not human interaction. Both isolated individuals are under strict monitoring, and authorities have stated that asymptomatic or presymptomatic transmission has not been reported. Singapore’s robust public health infrastructure, including rapid response protocols, ensures minimal risk to the general population.
