Impact of climate on western equine encephalitis in Manitoba, Minnesota and North Dakota, 1980–1983

Abstract

Information was collected on confirmed outbreaks of western equine encephalitis (WEE) in North America east of the Rockies for 1981 and 1983 (epidemic years) and 1980 and 1982 (non-epidemic years). The initial pattern of outbreaks in Manitoba, Minnesota and North Dakota was determined for each year. Backward (and in some instances forward) wind trajectories were computed for each day 4–15 days (incubation period) before the initial outbreaks of WEE in a given area of province or state. © 1989, Cambridge University Press.
