ECDC COMMUNICABLE DISEASE THREATS REPORT

Cholera - Cuba - Monitoring outbreak

Opening date: 4 July 2012 Latest update: 11 January 2013

 

Epidemiological summary

In June and July 2012, the communicable diseases surveillance system in Cuba recorded an increasing trend in diarrhoeal diseases, which were thought to be caused by high temperatures and heavy rains.

In Granma province, around 1 000 patients were reported to have been treated for gastrointestinal infections and among them 85 were confirmed to be infected with Vibrio cholerae.

Three of the confirmed cholera cases have died. Control measures were put in place and on 27 August 2012, the Cuban Ministry of Public Health declared the outbreak to be over.

Another 47 cases were confirmed in the aftermath of hurricane Sandy (October 2012), in the provinces of Santiago de Cuba, Camagüey and Guantanamo.

By the end of 2012, the cumulative number of cases reached 500. On 6 January 2013, the Cuban public health authorities notified an increase of acute diarrheal diseases in Havana. As of 14 January 2013, 51 cases of cholera have been confirmed in the capital and were subtyped to be Vibrio cholerae toxigenic serogroup O1, serotype Ogawa, biotype El Tor.

ECDC assessment

The report of 51 confirmed cases in Havana, Cuba, raises the risk for European travellers for contracting the disease, compared to the previous rapid risk assessment in July 2012 taking into account that half of the tourist arrivals to Cuba is to Havana. However, the overall risk should still be considered low.

Applying suitable preventive hygiene measures plays a key role in the prevention of the disease. Visitors to cholera-endemic or cholera-epidemic countries should always follow appropriate precautionary measures and drink only safe water (bottled water/water treated with chlorine), wash all fruits and vegetables with bottled or chlorinated water before consumption, regularly wash hands, avoid consuming raw sea-food products, and only eat sea food when thoroughly cooked.

Travellers should seek advice from travel medicine clinics to assess their personal risk. Physicians in the EU should consider the diagnosis of cholera in returning travellers from cholera endemic/epidemic countries including Haiti, the Dominican Republic and Cuba presenting with compatible symptoms. Physicians and clinical laboratories need to follow public health guidance on the notification of cholera cases.
