Two Outbreaks of Primarily Noninvasive Group A Streptococcal Disease in the Same Nursing Home, New York, 1991

Abstract

Group A Streptococcus has been identified as the cause of several outbreaks of infection in residents of nursing homes. These reports described outbreaks that included persons with severe invasive disease as well as more limited infection. The purpose of this report is to describe an investigation of two consecutive outbreaks of group A Streptococcus that occurred in a single nursing home, where all affected residents had disease of mild to moderate disease severity. This report focuses on the identification of risk factors for infection and describes the approach used to control the spread of infection in the nursing home.
