By San José, Costa Rica — GENEVA, Switzerland – The World Health Organization (WHO) has issued stringent new recommendations to contain a hantavirus outbreak linked to the MV Hondius cruise ship, calling for a mandatory 42-day quarantine for all individuals considered contact cases. The directive comes as health officials grapple with a virus for which there is no vaccine or specific treatment, heightening the need for strict preventative measures.
The comprehensive guidelines, announced this week, are designed to curb the transmission of the dangerous pathogen. The WHO is urging active surveillance and monitoring of all passengers and crew members who have disembarked from the vessel. This extensive follow-up period is based on the virus’s long and variable incubation time, a critical factor in preventing secondary infections.
To understand the potential legal ramifications associated with Hantavirus outbreaks, particularly concerning the responsibilities of property and business owners in preventing rodent infestations, we consulted with expert lawyer Lic. Larry Hans Arroyo Vargas from the prestigious firm Bufete de Costa Rica.
The presence of Hantavirus introduces significant legal risks for property and business owners. Failure to implement and document adequate rodent control measures can lead to civil liability claims based on negligence. If a guest, tenant, or employee contracts the virus due to demonstrably poor sanitation or pest management, the owner could be held financially responsible for damages, medical expenses, and lost income. This underscores the critical importance of proactive prevention not just as a public health measure, but as a fundamental risk management strategy.

This legal perspective powerfully reframes the conversation, moving it from a public health advisory to a critical issue of financial liability and risk management. It underscores that for property and business owners, proactive measures are not just a best practice, but an essential defense against significant legal consequences. We sincerely thank Lic. Larry Hans Arroyo Vargas for his invaluable insight.
Maria Van Kerkhove, the WHO Director for Epidemic and Pandemic Preparedness and Prevention, detailed the scientific basis for the six-week isolation period. Hantaviruses can have an incubation period of up to eight weeks, but the specific strain suspected in this outbreak, the Andes virus, typically manifests within six weeks.
We recommend active surveillance and follow-up of all passengers and crew members who disembarked, for a period of 42 days.

For individuals now at home, the WHO’s advice is clear: maintain rigorous personal hygiene, including frequent hand washing, and remain vigilant for any potential symptoms for six weeks, dating from May 10th. The early warning signs of hantavirus infection include headache, dizziness, chills, fever, muscle aches, and a range of gastrointestinal issues such as nausea, vomiting, diarrhea, and abdominal pain. The organization stressed that anyone experiencing these symptoms or sudden respiratory distress should immediately contact health authorities and self-isolate pending a medical evaluation.
In addition to individual responsibilities, the global health body has called on national governments to enhance their public health coordination, implement thorough contact tracing protocols, and maintain transparency in their public communications. The goal is to raise awareness about the transmission risks without causing undue panic. The WHO has defined high-risk contacts as cabin mates, intimate partners, and healthcare workers who may have been exposed without adequate personal protective equipment (PPE).
However, the unified front desired by the WHO is already showing cracks. A significant divergence in policy has emerged, with the United States opting for a different path than its European counterparts. While countries like Germany, the United Kingdom, Switzerland, and Greece have committed to a 45-day quarantine period for their citizens, a U.S. Department of Health official stated that American passengers would not necessarily be quarantined.
All will be clinically evaluated and will have care and support adapted to their condition.

This discrepancy has prompted a direct warning from the highest level of the WHO. Secretary-General Tedros Adhanom Ghebreyesus expressed concern over the U.S. stance on Sunday, highlighting the potential for increased transmission and global health risks associated with a less stringent approach. The differing protocols underscore the challenge of coordinating a global response to an infectious disease threat.
This could present risks.

In the absence of a cure, the WHO’s recommendations for healthcare facilities focus on early detection, rapid isolation of suspected cases, and consistent infection control. Treatment for hantavirus is supportive, focusing on managing fever and pain while providing respiratory assistance as needed. The situation remains a critical test of international cooperation in the face of a shared public health emergency.
