A rare hantavirus outbreak linked to the cruise ship MV Hondius has raised global concern after several passengers reportedly fell ill and three people died from the infection. Health authorities are now closely monitoring the situation as investigations continue.
According to reports, two Singapore residents who were onboard the vessel are currently isolated at the National Centre for Infectious Diseases (NCID) and are undergoing testing. One individual is experiencing mild symptoms, while the other remains asymptomatic.
The incident has sparked renewed attention on hantavirus, a potentially dangerous virus commonly spread by rodents.
Hantavirus refers to a group of viruses usually transmitted through contact with infected rodents, especially through their urine, droppings, and saliva. Humans can become infected after inhaling particles from dried rodent waste, particularly in enclosed or poorly ventilated spaces.
In severe cases, hantavirus can lead to Hantavirus Pulmonary Syndrome (HPS), a rare but serious respiratory illness that affects the lungs and can become life-threatening if not treated quickly.
Symptoms of hantavirus may appear anywhere from a few days to several weeks after exposure. Early symptoms often resemble the flu and may include fever, fatigue, muscle aches, headaches, chills, nausea, and vomiting. As the illness progresses, patients may develop a dry cough and shortness of breath.
Severe infections can rapidly worsen into breathing difficulties and lung failure, making early medical attention extremely important.
Health experts advise the public to take preventive measures to reduce the risk of exposure to rodents and contaminated environments. This includes sealing holes or gaps in homes, storing food properly, disposing of rubbish regularly, and keeping living spaces clean and dry.
If rat droppings are found, people are advised not to sweep or vacuum them immediately, as this may release virus particles into the air. Instead, gloves and a mask should be worn before spraying the area with disinfectant and carefully wiping it clean with paper towels.
Practising good hygiene also plays an important role in prevention. Washing hands regularly, avoiding touching the face, and disinfecting frequently touched surfaces can help reduce the risk of infection.
Travellers visiting rural or forested areas are also encouraged to take extra precautions. Authorities recommend avoiding sleeping in rodent-infested places, keeping food properly sealed, and following local health advisories while travelling.
While hantavirus infections remain relatively rare, health officials continue to urge the public to stay alert and maintain proper hygiene and cleanliness to minimise potential exposure.
