Editorial Note
Editorial Note: Serologic evidence of influenza A infection in
the
United States during August (possibly related to importation of the
virus) and sporadic isolation of influenza B virus during the
summer
and fall of 1987 were previously reported (1). The present report
documents influenza activity in the United States for the 1987-88
season. U.S. health-care providers should be alert for patients
with
influenza-like illness, which is characterized by sudden onset of
fever and chills accompanied by respiratory symptoms such as sore
throat or cough. Early collection and submission of specimens for
laboratory isolation will permit detection of further spread.
