The World Health Organization said Tuesday that recent earthquakes in Venezuela could trigger outbreaks of cholera, malaria, and yellow fever [1].

This public health alert follows a period of severe infrastructure collapse, where the loss of clean water and sanitation creates an environment for rapid disease transmission. The risk is heightened by the presence of overcrowded shelters and a healthcare system already under significant pressure.

The warnings come after two major earthquakes struck the country earlier this month [3]. The first quake measured 7.2 magnitude [1], while the second reached 7.5 magnitude [1]. These seismic events caused widespread damage to water supply systems and sanitation infrastructure [4].

According to the WHO, the combination of water scarcity and the failure of waste management systems creates a high risk for waterborne diseases. The organization also said the danger of vector-borne illnesses, such as malaria and yellow fever, can proliferate in disaster-stricken areas where standing water and displaced populations are common [1].

Health authorities said the crisis extends beyond infectious diseases. The disruption of medical services is expected to exacerbate chronic health conditions for residents who can no longer access routine care or medication [1].

Dr. Fabián Sandoval, who was interviewed regarding the crisis, discussed the current state of the response. The WHO alert, published June 30, 2026 [1], emphasizes that the Venezuelan health system is operating at its limit [4]. The agency is calling for urgent intervention to prevent a secondary disaster in the form of an epidemic [4].

Efforts are currently focused on restoring basic water access and providing medical supplies to overcrowded shelters to mitigate the spread of contagion [4].

“The World Health Organization said Tuesday that recent earthquakes in Venezuela could trigger outbreaks of cholera, malaria, and yellow fever.”

The intersection of natural disasters and a fragile healthcare infrastructure often leads to a 'second wave' of casualties. By flagging the risk of cholera and yellow fever, the WHO is signaling that the immediate trauma of the earthquakes is transitioning into a systemic public health crisis that requires international sanitation and medical support to contain.
