PETALING JAYA: Malaysians are urged to strengthen hygiene and rodent control measures to reduce the risk of hantavirus infection, although experts say the chances of a large-scale outbreak here remain low.
A news report on Thursday reported that two Singapore residents aboard the MV Hondius cruise ship were initially suspected of having hantavirus, though both later tested negative.
On Friday, Health Minister Datuk Seri Dr Dzulkefly Ahmad said no Malaysians were on board the ship, but urged vigilance.
Hantavirus is a rodent-borne virus transmitted to humans through air contaminated with rat urine, droppings or saliva.
Universiti Malaya virologist Dr Muhamad Afiq Aziz said precautionary measures should start with keeping the environment around the house clean and free from rodents.
“For the household, make sure food is fully covered. Clean and throw rubbish regularly to prevent it from attracting rodents.
“If there are rodent droppings, avoid sweeping them. Spray with disinfectant first and use gloves during cleaning and washing hands after.
“For the workplace, get regular pest control, storage areas should be kept clean and dry. Use gloves or a mask when dealing with potentially contaminated areas and proper waste management.”
He said hantavirus transmission risk remains low.
“Anyone who develops fever or breathing difficulties after possible exposure should seek medical treatment quickly.”
Virologist Dr Jasmine Elanie Khairat from Universiti Malaya also stressed prevention, as no specific antiviral treatment exists.
“At home, seal gaps and holes in walls, roofs and around pipes to prevent rodent entry.
“Double-bag dead rodents. And with heavy infestation around residential areas, schedule a pest control programme.
“The public should also report signs of infestation (e.g. rodent droppings, gnaw marks, nests) promptly,” she said.
She said among the typical viral‑associated symptoms are gastrointestinal symptoms that could lead to shock.
She urged authorities to strengthen rodent surveillance and port health checks.
