Epidemiological update: autochthonous cases of chikungunya fever in the Caribbean region and South America
21 Feb 2014
__
An outbreak of chikungunya in the Caribbean region was reported from the French part of the island of Saint Martin on 6 December 2013. It is the first time that autochthonous transmission of the virus has been documented in the Americas.
An ECDC risk assessment of the outbreak published on 12 December 2013 concluded that the risk of the disease spreading to other islands in the Caribbean region was high. Since then, autochthonous transmission of chikungunya has been reported from several islands in the Caribbean and recently for the first time in South America (French Guiana).
As of 21 February 2014, more than 5 900 suspected cases have been reported in the following locations:
The chikungunya transmission was detected during a concomitant dengue outbreak in the Caribbean. Both arboviruses are transmitted by the same Aedes aegypti mosquito species. The na?ve population, the presence of an effective vector in the region and the movement of people in and between islands and territories are factors that make it likely that the outbreak will continue to spread geographically and increase in numbers.
The conclusions and recommendations of the rapid risk assessment published on 12 December 2013 remain valid.
Clinicians and travel medicine clinics should remain vigilant regarding imported dengue and chikungunya cases from the Caribbean and French Guiana.
