In 2018, 147 human cases of West Nile Fever (WNF) were reported in Israel, of which 62 were suspected*. As expected, most of the morbidity occurred during the summer and autumn months, with over 50 patients in August alone. The level of morbidity was higher than the 2011-2017 average. Most of the patients this year resided in the Coastal Plain area. The distribution of patients by district was: North (19), Haifa (38), Central (54), Tel- Aviv (27), Jerusalem (1) and South (8). A significant increase was noted in the number of infected animals as compared to the last few years. אגף לאפידמיולוגיה Division of Epidemiology משרד הבריאות Ministry of Health ת.ד.1176 ירושלים P.O.B 1176 Jerusalem [email protected] [email protected] טל: 02-5080522 פקס: Tel: 972-2-5080522 Fax: 972-2-5655950 02-5655950 In 2018, WNV infected mosquitos were found in 42 locations in the country.

A human "confirmed" case refers to a patient whose lab test results show a definite infection with WNV. The final definition status of a case patient who initially was diagnosed as "suspected" may be changed to "confirmed" due to additional lab test results that were obtained over time. אגף לאפידמיולוגיה Division of Epidemiology משרד הבריאות Ministry of Health ת.ד.1176 ירושלים P.O.B 1176 Jerusalem [email protected] [email protected] טל: 02-5080522 פקס: Tel: 972-2-5080522 Fax: 972-2-5655950 02-5655950 Table 1: Positive test results for WNV in humans by location: Date sample Diagnostic status Locality No. Locality Chamber received in lab according to lab 1 Umm Al-Fahm 15/10/2018 Confirmed Natanya 2 Or Yehuda 25/07/2018 Confirmed Tel aviv Or Aqiva 12/08/2018 Suspected Hadera 3 Or Aqiva 02/09/2018 Suspected Hadera 4 Oranit 06/09/2018 Confirmed Petah-tiqwa 5 Azor 28/05/2018 Suspected Tel aviv 6 Elat 12/08/2018 Confirmed Beer Sheva 7 Elyakhin 25/06/2018 Confirmed Natanya 8 I'billin 09/01/2018 Suspected Akko Ashdod 22/07/2018 Confirmed Ashqelon 9 Ashdod 26/12/2018 Suspected Ashqelon Baqa Al-Gharbiyye 14/08/2018 Confirmed Hadera 10 Baqa Al-Gharbiyye 23/09/2018 Suspected Hadera 11 Binyamina-Giva'at Ada 29/08/2018 Suspected Hadera 12 Bizzaron 12/01/2018 Suspected Ashqelon Bene Beraq 15/07/2018 Suspected Tel aviv Bene Beraq 30/07/2018 Confirmed Tel aviv Bene Beraq 12/09/2018 Confirmed Tel aviv 13 Bene Beraq 21/09/2018 Suspected Tel aviv Bene Beraq 16/09/2018 Confirmed Tel aviv Bene Beraq 29/10/2018 Suspected Tel aviv 14 Basma 27/09/2018 Confirmed Hadera 15 Bazra 19/08/2018 Confirmed Natanya אגף לאפידמיולוגיה Division of Epidemiology משרד הבריאות Ministry of Health ת.ד.1176 ירושלים P.O.B 1176 Jerusalem [email protected] [email protected] טל: 02-5080522 פקס: Tel: 972-2-5080522 Fax: 972-2-5655950 02-5655950 Table 1: Positive test results for WNV in humans by location -
