The Ministry of Health (MoH) recently issued a press statement confirming that Brunei Darussalam has no hantavirus cases to date and remains at low risk for infection
The ministry stated that hantavirus is not endemic in Brunei, and there is currently no evidence of local transmission. Based on ongoing risk assessments, the likelihood of infection spreading within the country remains low.
As a precaution, the ministry advises individuals who have recently returned from affected areas, particularly Patagonia and Argentina, and who experience symptoms such as fever or respiratory illness, to seek immediate medical attention.

The update comes in response to international developments reported by the World Health Organization, which has been investigating a cluster of severe acute respiratory infections linked to a cruise ship expedition.
The vessel, MV Hondius, carried passengers and crew from multiple countries and was later associated with confirmed hantavirus cases and fatalities abroad. However, no cases linked to the incident have been detected in Brunei.
Hantavirus is a zoonotic disease caused by viruses carried by rodents. Human infection can occur through inhalation of contaminated dust containing urine, droppings, or saliva from infected rodents, or through contact with contaminated surfaces.
In some strains, human-to-human transmission has also been reported.
Early symptoms include fever, headache, muscle pain, fatigue, nausea, vomiting, and abdominal pain. Severe cases may progress to respiratory failure, low blood pressure, kidney complications, and death. At present, there is no specific antiviral treatment or vaccine, and management is mainly supportive, including fluid management, respiratory support, and dialysis when necessary.
As of 5 May 2026, eight cases have been identified internationally, including three deaths, involving nationals from several countries. The World Health Organization is continuing detailed investigations, with early findings suggesting that the initial case may have been infected prior to boarding in Argentina, with possible onboard transmission through close contact.
MOH will continue to monitor the situation closely at national, regional, and global levels, and ensure preparedness of health services. The public will be informed of any significant developments.
The public is also reminded to maintain good hygiene practices, including frequent handwashing and proper respiratory etiquette such as covering the mouth and nose when coughing or sneezing.
