WHO: hantavirus cruise outbreak is ‘not the start of a Covid pandemic’ – video

The World Health Organization (WHO) has determined that the broader public health threat resulting from a hantavirus outbreak linked to the cruise ship MV Hondius remains low. The assessment follows a series of cases identified among passengers and crew, prompting an international effort to monitor potential spread.

During a press briefing on May 7, 2026, WHO officials addressed the nature of the outbreak and the likelihood of a larger epidemic. While the current risk to the general public is categorized as low, officials noted that the situation requires continued vigilance due to the biological characteristics of the virus.

WHO Director-General Tedros Adhanom Ghebreyesus cautioned that the total number of cases may increase. He attributed this possibility to the long incubation period associated with hantaviruses, which can delay the onset of symptoms and complicate early detection in passengers who have already disembarked.

Abdirahman Mahamud, the WHO head of department for health emergency alert and response operations, stated that a large-scale epidemic is not anticipated. This assessment suggests that the transmission dynamics of the current outbreak are likely contained.

Addressing public concerns regarding the potential for a global health crisis, Maria Van Kerkhove, the acting director of the department of epidemic and pandemic threat, sought to distinguish this event from previous global health emergencies.

Van Kerkhove explicitly stated that the outbreak was not the start of a Covid pandemic, highlighting the fundamental differences in how hantaviruses operate compared to the SARS-CoV-2 virus.

Hantaviruses are a family of zoonotic viruses, meaning they are transmitted from animals to humans. They are typically spread through contact with the urine, feces, or saliva of infected rodents, often through the inhalation of aerosolized viral particles.

Depending on the strain and the geographic region, hantavirus infections generally manifest in two primary clinical forms: Hantavirus Pulmonary Syndrome (HPS) or Hemorrhagic Fever with Renal Syndrome (HFRS).

HPS is characterized by rapid respiratory failure and is most common in the Americas. HFRS, more prevalent in Europe and Asia, primarily affects the kidneys and can lead to acute kidney failure.

Because hantaviruses are not typically known for efficient human-to-human transmission—with the exception of specific strains like the Andes virus—public health experts generally view the risk of a widespread human pandemic as significantly lower than that of respiratory viruses like influenza or coronaviruses.

In the case of the MV Hondius, health authorities are focusing on the timeline of passenger movement. A global effort is currently underway to trace and notify passengers who left the ship before the outbreak was officially confirmed.

Contact tracing is critical in these scenarios to ensure that individuals who may be in the incubation phase receive appropriate medical monitoring. This prevents undetected cases from straining local healthcare systems if symptoms emerge suddenly.

The presence of a zoonotic virus on a cruise ship often leads investigators to examine the vessel’s pest control measures and the environments passengers visited during port calls. Identifying the original source of the infection is essential to prevent recurring outbreaks on similar vessels.

Public health agencies continue to monitor the health of those who were on board the MV Hondius. The focus remains on early symptom recognition and the implementation of supportive care, as there are currently no widely available vaccines for most hantavirus strains.

The WHO’s current stance emphasizes that while the MV Hondius incident is a serious medical event for those affected, it does not currently pose a systemic threat to global health security.
