A devastating mystery illness has gripped Cuba, pushing its healthcare system to the brink and sparking concerns of a potential cover-up by the government. With symptoms ranging from high fevers and red spots to peeling skin and swollen joints, the population is suffering, yet remains in the dark about the true nature of this disease.
The Canadian government has taken notice, implementing health screenings and quarantine measures for individuals returning from Cuba. Meanwhile, Spain has advised its citizens to steer clear due to a reported "serious epidemic."
Known simply as "the virus," reports suggest a staggering one-third of Cuba's population has been infected, with the British Medical Journal describing it as the country's most critical crisis in recent memory. As of December 17th, official reports indicated 52 deaths, primarily among children, with over 38,000 suspected cases. However, many Cubans believe the actual numbers are much higher.
Manuel Cuesta Morúa, a prominent human rights activist in Havana, claims the outbreak began in Matanzas around five months ago, with sudden deaths occurring. He alleges that the government has been issuing death certificates without mentioning the virus, effectively hiding the true extent of the crisis.
"These deaths were never officially attributed to the virus and were instead labeled as 'natural causes,'" Morúa told The Sun.
As the virus spread, the regime maintained its silence. By late October, health officials reported 13,000 new fever cases across the country within a week. Cemeteries in areas like Camagüey and Holguín have reportedly been overwhelmed.
Three months after the disease's spread, the Cuban government acknowledged the epidemic, but refused to declare a national health emergency. The disease has been described as a "combined arbovirus," where multiple viruses infect an individual simultaneously, making diagnosis challenging. It is believed to encompass dengue, Oropouche, Chikungunya, and other respiratory viruses like H1N influenza, respiratory syncytial virus, and Covid-19.
Cuban officials insist these diseases are common on the island. "They are neither new nor rare or unknown," stated Public Health Minister José Ángel Portal Miranda in October. He dismissed cover-up allegations, asserting, "No one can hide an epidemic or the dead."
While dengue has been endemic in Cuba for two decades, Chikungunya had rarely been detected before. In Havana, a popular tourist destination, Chikungunya infections have become prevalent, with many tourists arriving from southern Florida, especially Miami. The Florida Department of Health confirmed 149 cases of Chikungunya among travelers returning from Cuba.
Michael Lima, director of the rights-focused NGO Democratic Spaces, working closely with Cuban human rights activists, paints a dire picture. He describes the epidemic as a symptom of a larger, more sinister issue in Cuba that has been brewing for years.
"The country is facing a profound collapse of essential services," Lima said. "Chronic failures in the electrical grid, widespread shortages of food and medicines, deteriorating sanitation services, breakdowns in garbage collection, environmental sanitation, and severe social distress are all contributing factors."
A nurse from a clinic in Matanzas told El Pais, "It is not a lie to say that we are dying."
The situation was exacerbated by the arrival of Melissa, one of the strongest storms on record in the Caribbean, which caused major flooding on the island in November 2025.
With daily blackouts, Cuba lacks the fuel for fumigation, and insecticides are scarce. Donald Trump has issued a stark warning, stating that Cuba is "ready to fall" without military intervention.
According to Amnesty International, Cuba is experiencing its highest levels of repression in decades. Independent NGOs are restricted, and the free press is stifled, creating an environment devoid of transparency and accountability.
"This crisis is not accidental," Lima added.
In a country with a collapsed health system, 70,000 workers in the sector have resigned, and more than 30,000 doctors have emigrated in the last three years. Hospitals have closed, and others are overcrowded with patients.
Manuel said, "Authorities waited months before publicly acknowledging the scale of the Chikungunya outbreak and initially downplayed its severity. Citizens had to rely on social media and independent outlets for information. Even after recognizing the epidemic, official updates have been vague, offering little data on hospitalizations, regional spread, or deaths."
This has led to widespread accusations of a cover-up by the regime. In October, Cuban intellectual Alina Bárbara López posted on Facebook that authorities were "manipulating" the situation in Matanzas, where she resides.
"The order to deny the deceased of 'arbovirosis' is given," López wrote. "We have a hungry, ageing, stressed population, without medication for a long time to treat their chronic diseases. While the epidemic grew stronger, they hardly sold paracetamol or rehydrating salts in pharmacies. Such a scenario makes possible deaths that would not have happened otherwise."
The Sun has reached out to the Cuban Ministry of Foreign Affairs for comment.
So, what exactly is 'combined arbovirus'?
Combined arbovirus is not a single disease but a category of infections with similar characteristics, symptoms, and transmission methods. It describes a patient's condition that fits the profile of an insect-borne viral infection before a specific virus is identified. Most arboviral illnesses follow a standard incubation period, with symptoms appearing within 3 to 14 days after being bitten by an infected mosquito or tick.
Doctors group these illnesses together because they are clinically indistinguishable at the onset. Arboviral illnesses typically present in three ways:
Systemic/Febrile (Most Common): A sudden flu-like illness with high fever, chills, severe headache, muscle aches, joint pain, and skin rash and fatigue lasting for weeks.
Neuroinvasive (Most Serious): The virus enters the central nervous system, causing meningitis (stiff neck, fever, and light sensitivity), encephalitis (confusion, altered mental state, seizures, or tremors), or paralysis (sudden weakness in limbs, similar to polio).
Hemorrhagic (Specific Viruses): Seen in diseases like Dengue or Yellow Fever, with unexplained bruising, bleeding gums, or internal bleeding.
The situation in Cuba is complex and concerning, and it remains to be seen how the government will address these challenges. What are your thoughts on this unfolding crisis?
