Hantavirus Cases Worldwide: Full List of Countries Reporting Deadly Infections

A rare hantavirus outbreak linked to the cruise ship MV Hondius has triggered global concern, with multiple countries now monitoring passengers, reporting infections, and tracing possible contacts. Health authorities and the World Health Organization (WHO) have stressed that the public health risk remains low. However, countries continue to maintain surveillance due to the virus's long incubation period and the possibility of limited human-to-human transmission associated with the Andes strain.

The outbreak, which reportedly began during a voyage originating from Argentina, has so far resulted in confirmed infections and multiple deaths, prompting international tracking efforts across Europe, the Americas, and parts of Asia.

Countries Reporting Hantavirus Cases Or Monitoring Exposed Individuals

Argentina

Argentina is believed to be the origin point linked to the outbreak, with authorities retracing the movements of infected passengers before they boarded the cruise ship. The Andes variant associated with the outbreak is commonly found in South America.

Netherlands

The Netherlands reported fatalities linked to the outbreak, including a Dutch couple who died after exposure during the cruise. Dutch authorities also quarantined healthcare workers and monitored repatriated passengers.

Germany

Germany confirmed a fatal case involving a German passenger connected to the cruise ship outbreak.

France

France reported infected individuals and monitored multiple contacts after a French woman became critically ill and required intensive medical support.

United States

The United States evacuated and monitored several passengers exposed to the virus. American passengers were quarantined and medically evaluated after returning from the affected ship.

United Kingdom

The United Kingdom monitored and quarantined British passengers repatriated from the cruise ship following possible exposure to the virus.

Spain

Spain played a major role in evacuating passengers after allowing the affected ship to dock in Tenerife. Spanish authorities later confirmed at least one positive case linked to the outbreak.

Switzerland

Swiss health authorities monitored potential cases connected to passengers returning from the cruise outbreak.

South Africa

South Africa treated critically ill patients evacuated from the cruise ship and assisted with emergency medical response operations.

Italy

Italy quarantined several individuals suspected of exposure to hantavirus, although officials later confirmed that those tested were negative.

India

India activated precautionary surveillance after reports confirmed that two Indian nationals were aboard the affected ship. Officials stated that both individuals remained asymptomatic.

Other Countries Under Monitoring

According to international surveillance updates and health reports, countries including Chile, Brazil, Bolivia, Paraguay, Uruguay, Panama, Singapore, Denmark, and Canada have either recorded historical hantavirus cases or initiated monitoring measures linked to the recent outbreak.

What Is Hantavirus?

Hantavirus is a rodent-borne disease that can cause severe respiratory illness and kidney-related complications in humans. According to the WHO, the virus usually spreads through contact with infected rodent urine, saliva, or droppings. Certain strains, including the Andes variant, can rarely spread between humans through prolonged close contact.

HPS is mainly found in North and South America and is considered the more severe form of the disease. Symptoms include fever, muscle pain, fatigue, and severe respiratory complications that can rapidly progress to pulmonary edema and shock.

Key strains:

Sin Nombre virus (North America)
Andes virus (South America)

Common symptoms include fever, muscle pain, fatigue, coughing, and breathing difficulties. Severe infections may develop into hantavirus pulmonary syndrome (HPS), a potentially fatal respiratory condition if not treated early.

Is Hantavirus Becoming A Global Threat?

The WHO and health experts have clarified that the current outbreak is not comparable to COVID-19 and does not pose a pandemic-level threat at this stage. However, authorities continue aggressive monitoring due to the virus's high fatality rate and the international movement of potentially exposed passengers.

Health agencies worldwide are urging travellers and healthcare systems to remain alert while continuing contact tracing, testing, and quarantine measures wherever necessary.
