Cholera epidemic in eastern Cuba is on the decrease and not spreading to other regions of the country, Public Health Ministry confirmed in a statement on Saturday.

Since the disease was first spotted in Manzanillo - a city of 130,000 residents situated on the southern coast of Granma province - the Heath Ministry has confirmed 158 cholera cases and three deaths due to the infectious disease.

In its Saturday's statement, the Health Ministry said, "The outbreak of cases transmitted through water is diminishing, with no indication the illness has spread through food or other means."

The latest statement from the Pubic Health ministry came after numerous countries, including Canada, which is the biggest tourism provider for Cuba, have posted travel warnings.

The Ministry admitted that some isolated cases of cholera have been detected in other regions of the country, but the disease is not spreading further.

Cholera is an infection in the small intestine caused by Vibrio cholerae bacterium. The list of its main symptoms includes watery diarrhea and vomiting, which can lead to dehydration and even death in some cases.
