This is surprising and in apparent contrast with the low contagiousness observed with infections due to Epidermophyton floccosum. The epidemics reported only involved men. All observations made in the course of these epidemics indicated exposure to an exogenous source of infection. All attempts to find the source of infection remained unsuccessful; however, affirming Sabouraud's despairing remark 10 on a school epidemic in Paris Dans ces cas, le mode de propagation reste obscur.
