Surveillance For Hospital Outbreaks Of Invasive Group A Streptococcal Infections
Group A Streptococcal Infections
Hospital outbreaks of invasive group A streptococcal infection are a potentially preventable source of morbidity and mortality.
In Ontario, 291 cases of hospital-acquired invasive group A infection occurred between 1992 and 2000. Although nosocomial infections were most common in surgical and obstetric settings, most outbreaks of streptococcus A infection occurred outside of those settings.
One quarter of the outbreaks was related to community-acquired infections (mostly necrotizing fasciitis) requiring intensive care; the bacteria were primarily transmitted from patient to patient. Isolation of patients with necrotizing fasciitis may be an important strategy to reduce hospital outbreaks of invasive group A streptococcal infection.
