The World Health Organization (WHO) has clarified that the hantavirus responsible for the outbreak aboard the cruise ship MV Hondius is transmitted exclusively through close contact, with potential exposure to saliva or respiratory secretions. This occurs when an infected person sneezes, coughs, or spits very close to another, dispelling fears of widespread airborne transmission.
Definition of close contact according to experts
According to the WHO, close contact involves direct and intense interactions, such as sharing confined spaces for prolonged periods. In the case of the MV Hondius, which was sailing in Antarctica, several passengers reported symptoms after crossing paths in common areas. There is no evidence of transmission through surfaces or ambient air, which reduces the risk for the general population.
Historical context of hantavirus and previous outbreaks
The hantavirus comprises a group of viruses transmitted primarily by rodents, although human strains like the one causing the cruise ship outbreak are rare. In 1993, an outbreak in the U.S. caused 48 deaths, with fatality rates of 38%. Globally, the WHO registers about 200 confirmed annual cases, mostly in Asia and the Americas. In Latin America, outbreaks in Argentina and Chile have exceeded 100 victims in recent years, always linked to environmental exposure.
Recommended preventive measures
- Ventilate enclosed spaces to disperse secretions.
- Avoid direct contact with symptomatic individuals in confined environments.
- Use masks in high-risk groups during outbreaks.
- Monitor fever, muscle aches, and fatigue as initial symptoms of hantavirus.
Experts from the Centers for Disease Control and Prevention (CDC) agree: there is no vaccine or specific treatment, so prevention relies on hygiene and distance. On the MV Hondius, authorities isolated 10 affected individuals, with most recovering after medical support.
Risks in the Dominican Republic and the region
In the Caribbean, including the Dominican Republic, cases of hantavirus are uncommon, but surveillance is intensified in rural areas with rodents. The WHO urges reporting symptoms on maritime travel to contain rapid outbreaks in enclosed spaces.
This analysis underlines the importance of differentiating hantavirus from common respiratory pathogens, promoting informed calm in the face of health alerts.
