An outbreak of noninvasive group A streptococcal disease in a facility for the developmentally disabled.
BACKGROUND
Reports of outbreaks of group A streptococcal disease in long-term care facilities are uncommon.


METHODS
An outbreak of noninvasive group A streptococcal disease was investigated in a large facility for the developmentally disabled. The antistreptolysin O test was used to supplement the case finding.


RESULTS
Sixty-seven cases of streptococcal pharyngitis were diagnosed among residents and staff of the facility. Interventions based on enhanced infection control practices were effective, but maintaining them for several months was challenging because of the large number of staff, cognitive deficits of the residents, inconveniently placed areas for hand sanitation for the staff, and occurrence of a simultaneous outbreak of impetigo in the same population. After 4 months, the outbreak was successfully managed without chemoprophylaxis of the entire residential population and staff.


CONCLUSIONS
Outbreaks of group A streptococcal disease in centers for persons with developmental disabilities have unique challenges superimposed on routine outbreak response measures.
