Cholera in Ukraine
Epidemiological update, 10 June 2011
On 30 May 2011, Ukrainian authorities confirmed three cases of cholera in Mariupol City near the coast of Azov sea in Donetsk Oblast. Between 31 May and 9 June, the Ukrainian authorities reported 11 additional confirmed cases in Mariupol and one from the neighbouring Volnovakha rayon, bringing the total to 15 confirmed cases. Among them there are 14 adults and one child (18 months old). The date of onset of disease in the confirmed cases ranges from 24 May to 1st June 2011. All cases were hospitalised and no deaths are reported so far. As of 9 June, none of the neighbouring countries reported cases.
Three of the 15 cases are members of the same family.
According to the authorities, for this cluster, the source of contamination could be the consumption of fish.
The Ministry of Health established an Emergency Commission to lead the investigation and implement preventive measures, including a swimming ban in the sea and estuaries and the prohibition to catch or sell fish in the city of Mariupol.
Cholera has been reported in the past in Ukraine. Therefore, while the occurrence of cases is not unexpected, the number of cases being reported is unusual. With the current implemented measures for active surveillance and prevention, it is hoped that the numbers of newly reported cases will be limited. However, new cases can be expected, particularly in inhabitants and visitors to the city of Mariupol and Volnovakha rayon (region).
Cholera is an acute diarrhoeal infection caused by the bacterium Vibrio cholerae. Most individuals infected with V. cholerae remain asymptomatic or show only mild diarrhoea.
Symptomatic cases of human infection are characterised by nausea and abdominal discomfort, followed by acute watery diarrhoea (resembling rice water) and vomiting. About 20% of the cases can present a severe form of the disease with acute diarrhoea and severe dehydration which can lead to death (up to 50%) if left untreated. Among people receiving appropriate treatment, the case fatality rate is below 1%. The incubation period of this infection is between 18 hours and five days.
