Since West Nile is well on the way to becoming established as an endemic disease in the U.S., I suppose we all might as well get used to the idea that, sooner or later, we're likely to get it. (Unless someone comes up with a vaccine pretty fast.)

Does anyone know if one gets lifetime immunity after recovering from it? Don't know if that's an Iron Law of viral illnesses or not, but it sure would be nice if West Nile were a one-shot deal.

How about DDT?

I heard that one does become immune if exposed once. Also, that the vast, and I mean VAST majority of people infected either develop no symptoms, or recover after mild flu-like symptoms. I also heard a report that Interferon may help with the encephalitis, but I've heard no follow up on that.

The CDC website says it's a lifetime immunity after recovery, at least that's what they're saying now.
