This year is a milestone in the history of ECODEVELOPMENT as we are called upon to contribute decisively with our experience and expertise in the response to the epidemic of West Nile virus (a mosquito-borne disease) in the region of Central Macedonia. This disease will end in 2010 with 35 deaths and 262 identified cases and will continue to be a public health hazard in the coming years. Nowadays, the majority of the country’s integrated mosquito control programmes include specific actions against WNV.
