A cluster of four group A beta-hemolytic Streptococcus postoperative wound infections was investigated at a community hospital. The serotypes of the Streptococcus isolated from all four cases, an asymptomatic anesthesiologist and one of his household members were M nontypable T28. During the outbreak period, December 1988, the infection rate among the 40 patients of the anesthesiologist was 7.5%. Among other patients not having contact with this healthcare worker, it was 0.09% (p = .0002 Fisher's exact test). This is only the second reported Group A beta-hemolytic Streptococcus hospital outbreak in which the pathogen was traced to a member of a healthcare worker's household. Early outbreak detection and intervention limited the extent of the outbreak.
一家社区医院对一组4例A组β溶血性链球菌术后伤口感染病例进行了调查。从所有4例病例、一名无症状麻醉师及其一名家庭成员分离出的链球菌血清型为M不可分型T28。在1988年12月的暴发期间，该麻醉师的40例患者中的感染率为7.5%。在未与这名医护人员接触的其他患者中，感染率为0.09%（Fisher精确检验，p = .0002）。这是第二例报告的A组β溶血性链球菌医院暴发，病原体被追溯到一名医护人员的家庭成员。早期的暴发检测和干预限制了暴发的范围。
