West Nile fever summary for transmission season 2017

Nov 24 2017

The 2017 West Nile Fever transmission season in the European Union and European Economic Area (EU/EEA) and neighbouring countries is now over. During this season 203 West Nile fever cases were reported, with most cases being notified by Romania. For the first time this year, ECDC reported not only on human but also on equine cases. The last notified case in the EU/EEA had disease onset at the end of October (week 43). However, countries can still notify new or retrospective human and equine cases/outbreaks through respectively the European Surveillance System (TESSy) and Animal Disease Notification System (ADNS). ECDC will resume the monitoring at the start of the 2018 season, expected in June.

In the EU/EEA, the first cases of the 2017 season were notified by Greece at the end of July (week 30) and had a disease onset at the end of June. In the neighbouring countries, Israel notified the first West Nile fever cases early July (week 27). During the 2017 West Nile fever transmission season, 203 human West Nile fever cases were reported in the EU/EEA: Romania (66 cases), Italy (57), Greece (48), Hungary (21), Croatia (5), Austria (4), France (1) and Bulgaria (1). Eighty-four cases were reported in neighbouring countries: Serbia (49), Israel (28) and Turkey (7).

This season the case-fatality rate of West Nile fever was 9% with 26 reported deaths. After two consecutive years with no West Nile fever cases reported in Greece, 48 cases were reported in the country in 2017, including cases in areas where West Nile fever transmission to humans was not observed before. This year, Italy also reported cases in newly-affected areas, along the western coast (i.e. Livorno) and in the North-East of the country (i.e. Asti). France reported one case in the Alpes-Maritimes, a region bordering Italy, which is an area that did not experience any human West Nile fever cases previously.

This year, for the first time, ECDC included in its weekly epidemiological updates three types of West Nile fever maps: 1) human West Nile fever cases; 2) equine West Nile fever cases; 3) combined human and equine West Nile fever cases. Human cases are collected through TESSy and equine cases are collected through ADNS of the European Commission. While the distribution of human cases covers EU/EEA countries and neighbouring countries, equine cases cover only EU/EEA countries. Following a One Health approach, the maps aimed to highlight areas, at the NUTS3 level, where West Nile virus circulates in incidental hosts. This transmission season, 128 equine West Nile fever cases were reported by EU/EEA Member States through ADNS: 100 in Italy, 13 in Greece, nine in Spain, three in Hungary, two in Austria, and one in Portugal.

[FONT=&quot]Epidemiological update: West Nile virus transmission season in Europe, 2017

[FONT=&quot]28 Feb 2018[/FONT]

During the West Nile virus transmission season (June to November), ECDC publishes weekly epidemiological updates on human West Nile fever cases occurring in the European Union and the neighbouring countries. The updates are available via the Surveillance Atlas of Infectious Diseases. This year, for the first time, ECDC included equine West Nile fever cases in its epidemiological updates. During the 2017 transmission season, 204 human cases and 127 equine cases were reported in the European Union.[/FONT]


[FONT=&quot]Human cases

The first cases in the European Union were infected in Greece late June and were reported at the end of July. The last case of the season was infected in Hungary and was reported mid-November. In the neighbouring countries, the first case was reported by Israel at the beginning of July. The last case of this transmission season was reported by Turkey at the end of November; the case had disease onset early September.
In the European Union, 204 human West Nile fever cases have been reported: Romania (66 cases), Italy (57), Greece (48), Hungary (21), Austria (5), Croatia (5), France (1) and Bulgaria (1). In the neighbouring countries, 84 cases were reported: Serbia (49), Israel (28) and Turkey (7). Twenty-six deaths due to West Nile fever have been reported, with a case fatality of nine percent: Romania (14 deaths), Greece (5), Hungary (2), Serbia (2), Italy (1), Croatia (1) and Turkey (1).

Romania reported a 1.4-fold decrease of human cases compared to the year before. Few affected areas in Romania had no previous reports of West Nile fever cases. Italy also reported cases in newly affected areas, e.g. in Livorno, along the western coast and in the north of the country, in Asti. After two consecutive years without any West Nile fever cases, in 2017, Greece reported again cases, including in areas where no cases were ever reported before. France reported one case in the Alpes-Maritimes, at the border with Italy, an area where no human West Nile fever cases were reported before. The last time France reported an autochthonous case was in 2015.

Serbia reported a similar number of human cases compared to the previous transmission season (n=41), but more compared to 2015 (n=28). Turkey reported several cases more than the previous year, including cases in areas without previous cases (i.e. in Istanbul and Icel). Considerably fewer West Nile fever cases were reported by Israel compared to the previous years, i.e. 125 and 84 cases in 2015 and 2016, respectively. No West Nile fever cases were documented in Russia this year. In 2016, Russia reported 135 cases.


Equine cases

[FONT=&quot]This year, for the first time, ECDC included equine West Nile fever cases in its epidemiological updates. Equine cases are notified through the Animal Disease Notification System (ADNS) of the European Commission.

Following a One Health approach, the maps including human and equine data aim to highlight areas, at the NUTS 3 level, where West Nile virus circulates in incidental hosts. During the 2017 transmission season 127 equine West Nile fever cases were reported by EU Member States through ADNS: 92 in Italy, 13 in Greece, 13 in Spain, three in Hungary, three in Portugal, two in Austria and one in France.
