How to pronounce “west nile virus” in English

But we didn't have West Nile virus in people until 1999, because we had a very diverse bird flock around us.

This map is all the counties where West Nile virus-infected birds have been found.

And you're not so likely to get West Nile virus in humans.

And that's exactly what happened in 1999, with the first outbreak of West Nile virus in New York City.

Syndrome, new kinds of tick-borne illnesses, mosquito-borne viruses from dengue to chikungunya to West Nile virus.

So as long as you have a lot of diverse bird species around, including woodpeckers and rails, you don't have that much West Nile virus

And it turns out that, unlike woodpeckers and rails, robins and crows are excellent amplifiers of West Nile virus.

So the fewer woodpeckers and rails you have around, and the more robins and crows you have around, the more West Nile virus you have around.
