From 2005 to 2007, in Finland, the incidence of invasive Streptococcus pyogenes disease increased sharply, partly due to the uncommon emm84 gene becoming more prevalent from 2006 onwards. The overall case fatality rate of infections caused by strains carrying emm84 was not significantly different than that of infections caused by other types (7% versus 10%, respectively; P = 0.50).
2005年至2007年期间,在芬兰,侵袭性酿脓链球菌疾病的发病率急剧上升,部分原因是罕见的emm84基因从2006年起变得更加普遍。携带emm84的菌株引起的感染总体病死率与其他类型感染引起的病死率没有显著差异(分别为7%和10%;P = 0.50)。
