ProMED quoted GIDEON in this post:

there were at least 10 human cases in the Volga delta between
1963 & 1968, and that human seropositivity rates of up to 8 percent
were found in European Russia & Western Siberia (see ProMED post West
Nile virus - former Soviet Union: background 20060908.2548)

Quoted in ProMED:

Regarding recent cases in Afula, rates of West Nile fever in Israel have been strikingly similar to those of North America for the last 3 years. (See graph)
