Reuters reports that a US health alert earlier this month warned travelers and residents of a “significant increase in diarrhoeal illness across Cuba.
The alert said this was associated with the continuing degradation of the water and energy infrastructure.

The situation was compounded by the US’ imposed a fuel blockade in January.
