In a precautionary move, the World Health Organization (WHO) held a media briefing today to address a cluster of hantavirus cases linked to the cruise ship MV Hondius. The outbreak has resulted in eight reported cases, including three fatalities, with five confirmed as infections of the Andes virus—a strain known for rare human-to-human transmission in prolonged close contact. During the briefing, WHO Director-General Dr. Tedros Adhanom Ghebreyesus stressed that while the situation is serious, the public health risk remains low.
Dr. Tedros explained that the incubation period of hantavirus means that additional cases could still emerge, and the WHO is coordinating a global response. Since receiving reports on May 2, 2026, the organization has worked closely with multiple countries, adhering to the International Health Regulations, which guide countries and the WHO in handling public health emergencies.
Global Collaboration and Passenger Care
One of the core priorities, Dr. Tedros emphasized, is ensuring that the affected patients receive timely care. Additionally, the WHO is committed to safeguarding the remaining passengers, ensuring their safety, dignity, and support during disembarkation. A medical expert was deployed to the MV Hondius to evaluate passengers and crew, collecting vital data to assess infection risks. In addition, the WHO has arranged for 2,500 diagnostic kits to be sent from Argentina to laboratories in five different countries, aiming to improve testing capabilities.
The WHO is also preparing detailed guidelines for a safe and respectful disembarkation process. These guidelines will be implemented once passengers arrive at their destinations, ensuring that their onward travel is managed with care and safety in mind. Health authorities worldwide remain vigilant, closely monitoring the situation and ensuring that every measure is taken to prevent further spread.
India’s Vigilance: No Immediate Public Risk
Parallel to the global response, Dr. Naveen Kumar, Director of the National Institute of Virology in India, provided reassurance about the situation in his country. Despite reports of two Indian nationals onboard, Dr. Kumar emphasized that there is no immediate public health threat in India. The cases appear isolated, and there is no evidence suggesting community transmission. The WHO supported this assessment, noting that hantavirus infections are relatively rare and typically occur due to rodent exposure, not human-to-human spread.
India is fully equipped to manage hantavirus cases. Dr. Kumar highlighted that the National Institute of Virology, along with a network of 165 Viral Research and Diagnostic Laboratories, can swiftly identify and confirm suspected cases using advanced RT-PCR technology. He explained that symptoms usually appear one to five weeks after exposure and may initially resemble flu-like illnesses, such as fever, body aches, and fatigue, sometimes progressing to respiratory distress in severe cases.

WHO Responds to Hantavirus Cluster Linked to Cruise Ship, Assures Public Safety
In a significant development for global public health, Dr. Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization (WHO), convened a press briefing today to address a cluster of hantavirus cases tied to the cruise ship MV Hondius. As of today, eight cases have been reported, including three fatalities, with five of these confirmed as infections caused by the Andes virus. The Andes virus is notable as the only hantavirus known to have limited human-to-human transmission, typically requiring close, prolonged contact.
Dr. Tedros emphasized, “While this is a serious incident, WHO assesses the public health risk as low.” He underscored, however, that the virus’s incubation period means additional cases may arise, urging vigilance. The WHO has mobilized a coordinated response with several countries in line with the International Health Regulations, which define how nations and WHO cooperate during public health crises.
Global Coordination and Safety Measures Underway
Since receiving the initial alert on May 2, 2026, the WHO has taken swift action. A medical expert team was deployed to the ship to evaluate all passengers and crew members, gathering vital health data to assess risks. To bolster testing capacities, WHO organized the shipment of 2,500 diagnostic kits from Argentina to labs in five countries. These kits will help ensure rapid and accurate testing as health officials monitor the situation. Additionally, the WHO is developing guidelines for safe disembarkation and onward travel, ensuring passengers can proceed safely once they reach their destinations.
India Assesses Risk, No Immediate Threat
In parallel, Dr. Naveen Kumar, Director of India’s National Institute of Virology, addressed concerns about the outbreak in India. Two Indian nationals were aboard the MV Hondius, but Dr. Kumar confirmed there is no immediate public health risk in India. Despite these two cases, he stressed that they appear isolated and there is no evidence of community transmission. The WHO supported this assessment, noting that hantavirus infections are rare and usually occur from rodent exposure, not human transmission.
India’s Diagnostic Preparedness and Vigilance
Dr. Kumar reassured the public that India has robust diagnostic capabilities. The National Institute of Virology and a network of 165 viral research labs are equipped with RT-PCR technology, allowing for accurate detection of hantavirus. He noted that symptoms typically appear one to five weeks after exposure and can mimic flu-like illness, including fever, body aches, and fatigue. In severe cases, respiratory complications may arise.
Preventing Future Outbreaks: Vigilance and Hygiene
In light of this outbreak, both WHO and Indian health officials emphasize the importance of preventive hygiene measures. Dr. Kumar recommended that those working or traveling in rodent-prone environments stay alert, practicing hygiene and avoiding contact with rodents.
