Current data on West Nile Virus from the US Department of
Agriculture (http://www.aphis.usda.gov/vs/nahps/equine/wnv/)
includes the following statistics for equine cases:
Year Reported
---- --------
1999 25
2000 60
2001 738
2002 15257
2003 4554
The decrease from 2002 to 2003 is especially interesting in
light of the fact that the geographic spread of the virus
was larger in 2003 than in 2002. Is the vaccine responsible
for this marked decrease? Hard to say; correlation is not
proof of causation.
