A MIXED EPIDEMIC ASSOCIATED WITH ECHOVIRUS TYPES 6 AND 11

During 1979, an outbreak of mixed enterovirus Infections occurred in Kansas City and adjacent communities. Sixty-six enteroviruses and 7 adenoviruses were recovered from 73 persons in a survey hospital population. Twenty-eight persons yielded echovirus type 11, 22 echovirus type 6, and 16 either echovirus type 9 or Coxeackieviruses group B, types 2 and 3. This study describes some of the clinical, virologic and epidemiologic characteristics of the outbreak.
