On Tuesday, Miguel Díaz-Canel led a crucial meeting with health experts and scientists at Havana's Palace of Conventions, focusing on the potential threat of hantavirus. The Cuban health authorities are on high alert, implementing surveillance protocols to guard against the possible entry of this dangerous disease into the country.
The immediate cause for concern is an outbreak reported aboard the cruise ship MV Hondius. This vessel departed from Ushuaia, Argentina, on April 1 with 88 passengers and 59 crew members from 23 different nations.
The World Health Organization (WHO) was alerted on May 2 about passengers suffering from severe respiratory illness on board. By May 6, it was confirmed that the culprit was the Andes virus. As of May 12, there were nine laboratory-confirmed cases, two probable cases, and three fatalities: a Dutch couple and a German woman.
The outbreak has already spread to the Netherlands, Spain, France, Germany, the United Kingdom, Switzerland, and the United States, escalating the situation to a global health alert.
Heightened Vigilance and Prevention Measures
Dr. Carilda Peña García, the Deputy Minister of Public Health, spoke to the media following the meeting. She emphasized that Cuba has no cases or history of hantavirus outbreaks, and the island's 14 rodent species do not serve as virus reservoirs.
Nevertheless, she warned of the real threat posed by the virus's lengthy incubation period, which can be up to eight weeks. "Individuals carrying the disease could enter the country. Hence, I stress the importance of epidemiological monitoring at Cuba's borders," she stated.
Authorities have initiated inspections at ports, airports, and marinas to detect rodents on aircraft and ships, adhering to international health control protocols.
Learning from the COVID-19 Pandemic
The Andes strain is the only known hantavirus capable of person-to-person transmission, though limited to close and prolonged contact. Its mortality rate for cardiopulmonary syndrome cases ranges from 35% to 50%, and there is currently no approved vaccine or specific antiviral treatment.
Cuban officials are explicitly drawing from the lessons learned during the COVID-19 pandemic. "We have learned from COVID, a disease that spreads through respiratory pathways," Dr. Peña García remarked, recommending face masks to combat acute respiratory infections.
This comparison with COVID is significant in a nation still dealing with the aftermath of that crisis.
Challenges in the Cuban Health System
In 2025, Cuba grappled with uncontrolled outbreaks of dengue, chikungunya, and influenza H1N1 amidst a chronic shortage of medical supplies, casting doubt on the country's healthcare system's ability to tackle a new threat.
The WHO, however, has ruled out a pandemic scenario. "This is not another COVID-19. The current public health risk posed by the hantavirus is low," declared Director-General Tedros Adhanom Ghebreyesus in an open letter to the residents of Tenerife on May 9.
Dr. Peña García concluded her statements with a message for the Cuban population: "This is a situation the public should be aware of—not to cause alarm, but to remain informed and, most importantly, to focus on individual protection."
Understanding the Hantavirus Threat in Cuba
What is the hantavirus, and why is it a concern for Cuba?
Hantavirus is a life-threatening virus primarily spread by rodents. It has become a concern for Cuba due to an outbreak on a cruise ship, raising fears of the virus entering the country.
How is Cuba preparing for a potential hantavirus outbreak?
Cuba is implementing surveillance protocols, including inspections at ports and airports, to monitor for hantavirus carriers and rodent presence as part of their preventative measures.
What lessons from COVID-19 is Cuba applying to the hantavirus threat?
Cuba is applying lessons from COVID-19 by emphasizing respiratory protection and drawing on their experience with epidemic management to handle the hantavirus threat effectively.
