Havana Grapples with Public Health Crisis Amid Severe Water and Power Failures

A critical failure of water and power infrastructure in Havana is fueling a public health crisis, with Cuban and U.S. health authorities warning of a significant rise in viral illnesses. The situation, exacerbated by prolonged blackouts and a U.S. fuel blockade, has left millions of residents facing unsanitary conditions and a rampant spread of disease.

Infrastructure on the Brink

The crisis stems from Cuba's crumbling infrastructure, which is highly dependent on a stable power supply. According to Cuba’s National Institute of Hydraulic Resources, nearly 90% of the island's water system relies on electric-powered pumps. With blackouts in Havana now regularly exceeding 24 hours, the ability to supply water to the capital's nearly two million residents has been severely crippled.

This systemic failure has led to dire consequences for public hygiene. Residents report going days or even weeks without running water, forcing them to scavenge from broken pipes or purchase water from street vendors. Health workers cited by Reuters have noted a sharp increase in illnesses such as diarrhea and viral hepatitis, which thrive in unsanitary conditions.

Official Alarms and Widespread Impact

Both Cuban and U.S. officials have sounded the alarm over the deteriorating situation. Earlier this month, a U.S. health alert warned of a "significant increase in diarrheal illness across Cuba, associated ​with the continuing degradation of the water and energy infrastructure." Similarly, Cuban health authorities have issued warnings about the spread of viruses, including a strain of viral hepatitis.

The scale of the problem is extensive. The United Nations Office for the Coordination of Humanitarian Affairs has reported that approximately 3.5 million people, representing just under half of Cuba's population, are now suffering from water shortages. The crisis has been intensified since the U.S. imposed a fuel blockade in January, which has hampered the island's ability to generate electricity.
