Cuba has reported a new cholera outbreak with 163 cases, 12 of whom are tourists, though no deaths were mentioned, according to a bulletin from the Pan American Health Organization.

The PAHO update, dated Aug. 23, was based on information provided by epidemiological authorities on the island, where the new outbreak of the disease occurred in the provinces of Havana, Santiago de Cuba and Camaguey.

Cuban authorities have not yet reported the number of cases publicly, though this Tuesday a pro-government blogger known as Yohandry cited on his Web site the information from PAHO.

Cuban officials told PAHO that "in the course of this year suspected cases were regularly diagnosed."

"The cases registered in Havana were linked to two food-distribution centers, where the presence of asymptomatic carriers was found among those handling food supplies," the note said.

The Cuban Health Ministry's last public report on cholera was issued in January, after an outbreak was detected in Havana with 50 cases confirmed.

Cuba went some 50 years without any cases of the illness until August 2012 when it reappeared, chiefly in the eastern region, causing three deaths and 417 people infected, according to official data.

PAHO said in its latest bulletin that Cuba also registered another outbreak with 47 confirmed cases after Hurricane Sandy in October 2012.

The last cholera epidemic in Cuba was in 1882. EFE
