One hundred and twenty-six cases of pityriasis rosea seen over two years in north Staffordshire were analysed for clustering in time and space. A statistically significant degree of clustering was found; this was evident among female patients considered separately but not among male patients. The incidence of the condition was higher in patients working in, or attending, educational establishments. These findings support the hypothesis that pityriasis rosea is caused by an infective agent. A search for an infective organism and a transmission mechanism now seems justifiable.
对北斯塔福德郡两年间确诊的126例玫瑰糠疹病例进行了时间和空间上的聚集性分析。结果发现存在具有统计学意义的聚集程度;这种聚集现象在单独分析的女性患者中明显,但在男性患者中不明显。在教育机构工作或上学的患者中,该病的发病率更高。这些发现支持玫瑰糠疹由感染因子引起这一假说。因此,现在寻找感染源和传播机制似乎是合理的。
