2018 West Nile fever transmission season
Situation update
----------------------------------------
Between 30 Nov and 6 Dec 2018, EU Member States reported one human West Nile virus infection in Hungary. The most recent onset date reported by Hungary was from week 45, 5-11 Nov 2018. 18 cases were reported by EU neighbouring countries, all by Turkey, with the most recent date of onset reported from week 38, 17-23 Sep 2018. In 3 areas in Turkey human cases were reported for the 1st time. All other human cases were reported from previously affected areas. 3 deaths were reported this week in Turkey (2) and Italy (1).

In the same week, no new outbreaks among equids were reported.

In 2018, as of 6 Dec 2018, EU Member States have reported 1503 human cases in Italy (576), Greece (311), Romania (277), Hungary (215), Croatia (53), France (27), Austria (20), Bulgaria (15), the Czech Republic (5), Slovenia (3) and Cyprus (1). EU neighbouring countries reported 579 human cases in Serbia (415), Israel (128), Turkey (22) and Kosovo* (14). To date, 180 deaths due to West Nile virus infection have been reported by Greece (47), Italy (46), Romania (43), Serbia (35), Kosovo* (3), Bulgaria (2), Turkey (2), the Czech Republic (1), and Hungary (1).

During the current transmission season, 285 outbreaks among equids have been reported by Italy (149), Hungary (91), Greece (15), France (13), Spain (9), Austria (2), Romania (2), Germany (2), Slovenia (1) and Portugal (1).

In accordance with European Commission Directive 2014/110/EU, prospective blood donors should be deferred for 28 days after leaving an area with evidence of WNV circulation among humans unless the results of an individual nucleic acid test are negative.

As expected at this time of the year, only very few cases are currently being reported. However, the latest date of onset was reported from week 46, 12-18 Nov, which represents an unusually late date of onset since in past transmission seasons in the EU/EEA and EU neighbouring countries, the latest date of onset typically occurred between weeks 39 and 42. ECDC will continue publishing weekly West Nile virus updates until no new cases with disease onset in the previous 4 weeks have been reported.

*This designation is without prejudice to positions on status, and is in line with UNSCR [UN Security Council resolution] 1244 and the International Court of Justice Opinion on the Kosovo Declaration of Independence.

[According to the report above, the number of WNV cases reported has decreased. However, the total cases reported during 2018 is considerably higher, with Italy, Greece, and Romania reporting the highest numbers. Reduced vector activity on account of lower temperatures may be one factor contributing to this reduction. - Mod.UBA
