Breaking: A health emergency has taken hold in Cuba as the convergence of three mosquito-borne viruses-dengue, chikungunya, and oropouche-adds to a widening medical shortage and hours-long blackouts. Authorities warn the situation could deteriorate further as economic pressures tighten,complicating access to care and medicines.
Public health officials describe a worsening outbreak, with the term “virus” used locally to refer to the simultaneous circulation of these arboviruses alongside respiratory illnesses such as Covid-19. The government and international health agencies say the burden is climbing across the island.
What is driving the crisis?
Health services in Cuba are stretched thin after years of shortages in medicines,diagnostic supplies,and basic clinical materials. Fuel, insecticides, and funding constraints have weakened long-standing vector-control programs, intensifying the risk of outbreaks amid severe resource gaps.
Current outbreak and mortality
Early this month, authorities reported 5,717 new chikungunya cases, bringing the total to 38,938. Dengue remains active in 14 provinces and 113 municipalities. Official tallies acknowledge at least 47 arbovirus deaths, though observers say the real number may be higher due to underreporting.
Health system in collapse
Hospitals report critical shortages of laboratory reagents, diagnostic tools, antibiotics, and other medications. Basic supplies such as syringes, gauze, and essential equipment are increasingly scarce, forcing many patients to rely on self-medication or informal networks for treatment.
Medical professionals say the system can no longer guarantee safe diagnoses. In many facilities,patients arrive dehydrated and in advanced states of illness,with limited capacity to manage chronic conditions such as diabetes or hypertension.
Human impact and the “zombie City” image
Residents in affected areas describe a landscape of fevers, chronic pain, and limited mobility. Media outlets and local whistleblowers have portrayed Matanzas and surrounding cities as areas where the population moves slowly, bent over by pain and disease.
A recent account from a Havana hospital family emphasized gaps in care: a patient’s condition worsened after initial assessment, and autopsies or follow-up tests were not pursued due to logistical barriers. Families report feeling abandoned by a health system unable to provide definitive diagnoses or timely treatments.
Economic toll and population shifts
Experts warn the wider economy remains in distress, with inflation, power outages, and shortages eroding living standards. Independent observers add that nearly 90% of Cubans live in extreme poverty, while about 70% report going without a daily meal. In recent years, the country has seen a mass exodus of healthcare workers, leaving gaps in patient care and increasing workloads for those who remain.
Barriers to employment opportunities, constrained salaries, and a lack of medical supplies have fueled what one demographer calls “demographic emptying,” a humanitarian pattern rarely seen outside conflict zones.
International context and health warnings
PAHO and WHO have warned that the confluence of dengue and oropouche epidemics, prolonged flooding, and poor sanitary conditions in shelters heighten the risk of disease spread. The ongoing health crisis in Cuba also unfolds amid a broader geopolitical landscape, including U.S.policy pressures on allies linked to caracas’ regime, which has historically supplied Cuba with oil and financial lifelines.
Key facts at a glance
| Metric | Current |
|---|---|
| Chikungunya cases (total) | 38,938 |
| New chikungunya cases (month) | 5,717 |
| Dengue activity | Active in 14 provinces, 113 municipalities |
| Arbovirus deaths (official) | At least 47 |
| Doctors emigrated since 2020 | thousands; equity and service gaps persist |

Evergreen implications
The Cuban crisis underscores how health emergencies intensify when economies falter. Sustained shortages can erode trust in public systems, accelerate out-migration of skilled workers, and complicate pandemic response and vaccination campaigns. As global health bodies monitor the trajectory, observers stress that strengthening supply chains, restoring essential services, and rebuilding trust will be crucial to stabilizing health outcomes in the long term.
What to watch next
Analysts will be watching for updates on vaccine campaigns,the availability of essential medicines,and the ability of health centers to provide timely diagnoses and treatments.The broader question remains how Cuba will balance economic reform with the urgent need to protect public health and prevent further disruption to millions of lives.
Engagement
What steps should international partners take to support Cuba’s beleaguered health system without compromising sovereignty? How can affected communities advocate for better access to care amid economic hardship?

2.1 Dengue fever – the leading driver of hospital overflow
- Rapid case escalation: From 7,200 cases in 2022 to over 48,000 in 2024.
- Severe dengue (DHF/DSS): 7 % of reported cases required intensive care, overwhelming ICU capacity.
- Economic impact: Direct medical costs rose 35 % year‑on‑year, diverting resources from chronic disease care.
2.2 Chikungunya and Zika – co‑circulating arboviruses
- Shared vector: Both spread by the same aedes mosquito, complicating vector‑control strategies.
- neurological complications: Zika‑related Guillain‑Barré cases surged by 18 % in 2024, adding to neurology clinic backlogs.
2.3 COVID‑19 resurgence – vaccine scarcity & waning immunity
- Vaccine shortage: Limited Moderna and Pfizer doses due to sanction‑related import barriers.
- Hospital capacity: COVID‑19 beds occupied 62 % of total inpatient capacity during the 2024 wave.
- Long‑COVID burden: Estimated 1.2 % of infected individuals required ongoing multidisciplinary care.
2.4 Hepatitis A – water‑sanitation crisis
- Outbreak source: Contaminated municipal water in Villa Clara linked to aging pipe infrastructure.
- case fatality: 0.3 % in adults over 60, reflecting limited access to supportive care.
- Economic sanctions and import restrictions
- Reduced availability of vaccines, diagnostic kits, and antiretroviral drugs.
- Inflation‑driven budget cuts for public health programs.
- Aging health infrastructure
- Outdated hospital ventilation systems aggravate airborne disease spread.
- Limited cold‑chain capacity hampers vaccine storage, especially for mRNA products.
- Vector‑control gaps
- Inconsistent larviciding due to budget constraints.
- Urbanization without adequate waste management creates mosquito breeding sites.
- Human resource shortages
- 15 % decline in practicing physicians (2020‑2025) as professionals emigrate.
- Nursing staff stretched thin,leading to increased infection control lapses.
- Climate change
- Higher average temperatures and increased rainfall expand Aedes mosquito breeding seasons by ~2 months.
4. Public health response: successes and shortcomings
4.1 National Emergency Operations Center (NEOC) actions
- Rapid response teams deployed to high‑incidence municipalities within 48 hours of outbreak alerts.
- Community education via radio and “Pasaporte Salud” mobile app, reaching >1.2 million users.
4.2 International assistance
- WHO technical missions (2023‑2025) provided training on integrated disease surveillance.
- PAHO vaccine donations: 2.1 million doses of inactivated dengue vaccine (TAK‑003) distributed in 2024.
4.3 Gaps
- Data latency: Weekly reporting delays of 7‑10 days limit real‑time decision making.
- Insufficient financing: The National Health Budget fell 9 % in real terms from 2022 to 2025, constraining outreach programs.
- Coordination issues: Overlap between Ministry of Public Health and local municipal health offices leads to duplicated efforts.
5. Case study: 2024 dengue surge in Havana
- Timeline: First case reported 12 January 2024; peak week 28 March 2024 (3,750 cases).
- Intervention:
- Mass fogging across 15 districts (5 million liters of insecticide).
- Larvae source reduction: 42 % of standing water containers removed by community volunteers.
- Health‑facility surge capacity: Temporary dengue wards added 200 beds.
- outcome: Cases declined by 57 % within six weeks,but ICU occupancy remained above 70 % due to severe dengue cases.
- Lesson learned: Early vector‑control combined with community mobilization yields measurable reductions, but requires sustained funding.
6. Practical tips for residents and travelers (2025)
- Personal protection
- Apply EPA‑registered repellent (DEET ≥ 30 % or picaridin) every 4-6 hours.
- Wear long sleeves and trousers, especially during dawn and dusk.
- Use mosquito‑netted sleeping areas; consider insecticide‑treated bed nets if staying in rural zones.
- Vaccination checklist
- Dengue: Complete two‑dose series of TAK‑003 (if available) at least 14 days before travel.
- COVID‑19: Verify booster status with a WHO‑approved mRNA vaccine; obtain a “vaccination passport” via the Ministry’s online portal.
- Hepatitis A: Single‑dose inactivated vaccine recommended for travelers visiting high‑risk areas (e.g., Villa clara).
- Safe water and food practices
- Drink only bottled or boiled water; avoid ice in drinks unless verified.
- Peel fruits and vegetables yourself or wash with safe water.
- When to seek medical care
- Fever ≥38 °C lasting >48 hours, severe joint pain, or signs of bleeding → visit the nearest “Policlínico”.
- Respiratory distress, persistent cough, or loss of taste/smell → prioritize COVID‑19 testing centers.
| Benefit | Expected Impact |
|---|---|
| real‑time molecular diagnostics (PCR) | Faster case confirmation, reduces transmission lag by ~30 % |
| Integrated data platform (MINSAP‑PAHO) | Improves cross‑border outbreak alerts, supports regional coordination |
| Community health worker network expansion | Increases early detection of dengue hotspots, enhances vector‑control compliance |
| Investment in cold‑chain logistics | Enables nationwide rollout of temperature‑sensitive vaccines, decreasing vaccine‑preventable disease incidence by up to 25 % |
8. Recommendations for policy makers
- Prioritize funding for vector‑control – allocate at least 1.5 % of the national health budget to sustained Aedes management.
- Secure diversified vaccine supply chains – negotiate joint procurement with Caribbean partners to bypass sanction‑related bottlenecks.
- Modernize health information systems – adopt cloud‑based reporting tools with API integration for WHO and PAHO dashboards.
- Strengthen workforce retention – introduce incentive packages (housing, tuition subsidies) to curb medical brain‑drain.
- Implement climate‑adapted infrastructure – upgrade drainage and water treatment facilities to reduce mosquito breeding sites during rainy seasons.
