Authorities stress no local link to cruise outbreak while warning of rodent-borne risks at home.
Indonesian health officials are urging vigilance after a hantavirus outbreak aboard the MV Hondius cruise ship in Europe, even as they stress that recent cases detected in Indonesia are unrelated and that no human-to-human transmission has been seen locally.
Cruise Ship Outbreak Prompts Global Alert
Concerns over hantavirus escalated after the World Health Organization (WHO) received reports on May 2 of several passengers aboard the Dutch vessel MV Hondius suffering from severe respiratory illness. By May 8, WHO confirmed that at least six of eight suspected cases from the ship were hantavirus infections, all caused by the Andes strain, which has shown limited person-to-person transmission in Argentina and Chile. WHO officials have classified everyone on board as high-risk contacts but say the risk to the wider public remains low.
Singapore Residents Negative After Close Exposure
Among the Hondius passengers were two Singapore residents who had been on the same flight as a confirmed hantavirus case travelling from St Helena to Johannesburg on April 25, according to Singapore’s Communicable Diseases Agency. The confirmed case did not travel to Singapore and later died in South Africa. The two Singapore residents tested negative after being quarantined on arrival and will remain in quarantine for 30 days from their last exposure, with repeat testing before release.
Indonesia’s Cases Unrelated To Hondius Outbreak
Indonesia has recorded 23 confirmed hantavirus infections since 2024 out of 251 suspected cases, with three deaths. In 2026 so far, five cases have been detected. Health Ministry spokesman Aji Muhawarman said none of these patients had recent travel abroad and there is no connection to the Hondius cluster. On May 8, two suspected cases in Jakarta and Yogyakarta were ruled out by lab testing. “Until now, we haven’t recorded any more hantavirus cases in Indonesia,” Aji told Kompas.com, adding that all known local infections involve the Seoul strain, not the Andes strain seen on the cruise ship.
Virus Types, Symptoms And Lack Of Specific Treatment
Hantaviruses are rodent-borne viruses transmitted to humans mainly via inhalation of dust contaminated with urine, droppings or saliva from infected rodents, and occasionally via bites. WHO estimates 10,000 to over 100,000 infections occur annually worldwide, mostly in Asia and Europe, with case fatality rates up to 15 per cent there and up to 50 per cent in the Americas. The Andes strain can cause hantavirus cardiopulmonary syndrome, a rapidly progressive disease affecting lungs and heart. Strains circulating in Europe and Asia, including Seoul, tend to cause haemorrhagic fever with renal syndrome, affecting kidneys and blood vessels. Symptoms typically appear one to eight weeks after exposure and include fever, headache, muscle aches, abdominal pain, nausea and vomiting. There is no licensed specific antiviral or vaccine; care focuses on managing respiratory, cardiac and renal complications.
Clean Living, Not Panic, Urged At Home
Health Minister Budi Gunadi Sadikin has said Indonesia is working with WHO to strengthen surveillance and early detection, but experts emphasise that panic is unwarranted. Paediatrician Piprim Basarah Yanuarso, head of the Indonesian Paediatric Society (IDAI), called for calm and encouraged people to reduce rodent contact by keeping food and living areas clean. “In every outbreak of an infectious disease, the key is a clean and healthy lifestyle,” he said at an IDAI briefing on May 8. WHO epidemic preparedness director Maria Van Kerkhove and WHO chief Tedros Adhanom Ghebreyesus, who travelled to Tenerife to oversee the Hondius evacuation, have also stressed that while the cruise outbreak is serious, “this is not another Covid-19.”
The MV Hondius hantavirus outbreak has sharpened global awareness of a long-known rodent-borne threat, but Indonesian authorities say local infections remain limited, unlinked to the cruise cluster and confined to strains not known for human-to-human spread. For Indonesians and Singaporeans, the key messages are vigilance, good environmental hygiene and trust in surveillance systems, rather than fear, as health agencies work with WHO to track cases and protect communities.
