Twenty four new human cases of West Nile fever have been reported for the EU and 83 for its neighbourhood over the past week.

Twenty new cases were reported in Greece by the Hellenic Centre for Disease Control and Prevention (KEELPNO). Only one probable cases comes the newly affected prefecture of Pella. Nineteen cases were found in areas with previous case reports: in the prefectures of Achaia (1), Aitoloakarnania (1), Attiki (2), Kavala (3), Thessaloniki (1), Xanthi (11). (See KEELPNO Weekly bulletin for more information). New cases and affected areas in Greece are not unexpected given that since 2010 there has been progressive geographical expansion of West Nile virus transmission throughout the country, as stated in the recently published ECDC risk assessment on the epidemiological situation of West Nile fever in Greece.

Romania reported four new confirmed cases: two from the newly affected counties of Giurgiu and Ialomita and two from Bucuresti municipality (Bucharest), an area with previous case reports.

In neighbouring countries, new cases of West Nile fever were found in Israel (11) and the occupied Palestinian territory (1); 70 new cases have been also reported in Russia, 11 in a new area and 59 in areas with previous case reports.

Every Friday ECDC publishes on its website the West Nile fever maps, the information being based on cases reported up to the Thursday of each week.
