RE: WNV in Birds in Mexico, WNV antibodies in Birds in DR

CDC presented a good animation of WNV spread in 2002 that seemed to show
spread south to north along river corridors. Interesting, the locations
where WNV was detected first seemed to have the most severe outbreaks.
Within a given season, it seems to spread like a fire.

Would point out that the pattern of spread in the U.S. has not been along
migratory bird flyways either. Spread north and south, then progressively
further west from the original Long Island epicenter. Made it as far as the
Mississippi in 2001, heavy case load to the Rockies in 2002 with isolated
positives beyond the Rockies. Going from east to west across Canada as
well.
