Twenty new human cases of West Nile fever have been reported for the EU and 33 for its neighbourhood over the past week.

Twenty new human cases of West Nile fever have been reported for the EU and 33 for its neighbourhood over the past week. Ten new cases were reported in Greece by the Hellenic Centre for Disease Control and Prevention (KEELPNO) – only one case from a newly affected prefecture (Arta), eight are in areas with previous case reports (Attiki 1, Drama 2, Imathia 1, Kavala 2, Lefkada 1, Thessaloniki 1) and one, whose location is to be confirmed (Aitoloakarnania). (See the 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.

In Hungary, four new West Nile fever cases have been found (three from the newly affected counties of Baranya, Pest and Vas), in Italy - six (two from the newly affected provinces of Pordenone and Gorizia).

In neighbouring countries, for the first time this year the Former Yugoslav Republic of Macedonia reported four cases of West Nile fever, from the Skopje region and the municipalities of Krusevo, Lipkovo and Struga. Fourteen new cases have been found in Russia, nine - in Israel and one in Croatia.

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