St. Louis encephalitis outbreak--Arkansas, 1991.
On August 2, 1991, a neurologist in Pine Bluff (Jefferson County) in central Arkansas notified the Arkansas Department of Health of two patients hospitalized with St. Louis encephalitis (SLE). A hospital chart review and heightened surveillance (i.e., notification of physicians and hospital infection-control coordinators in Jefferson and surrounding counties) subsequently identified 24 confirmed or probable cases of SLE. This report summarizes the findings of the ongoing outbreak investigation.
