Mosquito-Borne Illnesses Ravage Cuba, Claiming 33 Lives
A devastating outbreak of mosquito-borne illnesses has struck Cuba, resulting in the deaths of 33 people, including 21 children, since July. The primary culprit behind these fatalities is the chikungunya virus, which has been responsible for the majority of the deaths, while the flu-like dengue virus has claimed 12 lives, according to Carilda Pena, Cuba’s deputy health minister.
The chikungunya virus first emerged in Cuba’s western Matanzas province in July but has since spread to all 15 provinces of the country, which has a population of 9.7 million people. This virus, first identified in Africa in the early 1950s, is characterized by severe joint aches, fever, and fatigue, as stated by the Centers for Disease Control and Prevention (CDC). Symptoms typically manifest within three to seven days after a bite from an infected mosquito, and while most people recover within a week, some may experience severe joint pain for months or even years after their illness.
Understanding Chikungunya and Dengue
Chikungunya and dengue are both transmitted by the bite of an infected mosquito. While deaths from chikungunya are rare, certain groups, such as newborns infected around the time of birth, people over 65, and individuals with preexisting medical conditions, are more likely to experience severe illness. The CDC emphasizes that there is no specific treatment for chikungunya, but vaccines are available and recommended for people visiting areas experiencing an outbreak. It’s also crucial to note that the disease cannot be spread from person to person.
Cuba, renowned for its medical and pharmaceutical expertise, had previously dealt effectively with a chikungunya outbreak in 2014. However, this time, the outbreak has spiraled out of control, attributed to a lack of hygiene, accumulated garbage, and people storing water in tanks due to the intermittent availability of clean tap water. The country’s economic crisis, exacerbated by U.S. sanctions and a severely impacted tourism sector due to Covid, has led to a decline in medical services and prevention programs, including mosquito fumigation.
Global Implications and Precautions
The CDC has issued travel notices for Americans traveling to countries with chikungunya outbreaks, including Cuba, advising increased precautions such as vaccination and measures to prevent mosquito bites. Other countries, including China and those near the Indian Ocean like Madagascar and Kenya, have also been named in these travel notices. Notably, New York recently reported its first-ever locally acquired case of chikungunya in October 2025, marking the first such case in the U.S. since 2019. This highlights the potential for the virus to spread beyond international borders.
As Cuba battles this outbreak, it’s essential for travelers and residents alike to be aware of the risks and take necessary precautions. The situation underscores the importance of robust public health measures, including mosquito control programs and access to clean water, in preventing the spread of such diseases.
