Cuban hospitals are struggling to provide basic medical services as power outages and fuel shortages cripple the healthcare system [1].

The crisis threatens the lives of thousands of patients who cannot access critical care. As the energy grid fails, the inability to maintain refrigeration for medicines and power for surgical equipment creates a systemic collapse of public health.

Medical facilities across Cuba, including those in Havana, are facing power outages that last up to 20 hours [1]. These failures have forced the healthcare system to delay more than 100,000 surgeries [1]. This instability follows a pattern of grid failure, with the country experiencing its third nationwide blackout this month [4].

Government officials said the crisis is due to a de facto U.S. oil blockade resulting from tightened sanctions [2, 3, 5]. The lack of oil and diesel supplies has left generators idle and the national power grid unable to sustain basic operations [3].

"The situation is extremely tense," a Cuban official said [3].

Despite the humanitarian toll, the geopolitical tension remains high. While the U.S. offered $100 million in aid to address the power grid collapse [5], the underlying fuel shortages continue to impede the delivery of essential health services [1, 2]. Health-care workers said they have an increasing inability to provide even the most basic care as the energy deficit persists [1, 2].

“Power outages lasting up to 20 hours”

The intersection of U.S. sanctions and Cuba's aging energy infrastructure has created a humanitarian bottleneck. By limiting the import of fuel, the sanctions effectively disable the backup systems required to keep hospitals operational during grid failures, transforming a technical energy problem into a critical public health emergency.
