[Epidemiology of Microsporum langeronii tinea capitis in the Paris suburban area. Results of 2 school and familial surveys].

Introduction: One epidemiologic survey was carried out in two children communities, following detection of several cases of Microsporum langeronii tinea capitis.

Patients And Methods: In one case, 3 year-old children from a day-nursery were contaminated by a child originating from France, who had been previously infected by contact with a friend originating from Ivory Coast. In the second case, lesions were diagnosed in a nursery-school in African children born in France. These were treated before epidemic progression into the school.

Results: Our study confirms data from the literature concerning the risk of contamination by Microsporum langeronii, with a familial contamination being more frequent than scholar one.

Discussion: The interest of our study was the rapid starting of the epidemiologic survey after first case diagnosis (one to two months) and the treatment of all the patients without scholar eviction. Treatment of all affected patients as well as "asymptomatic carriers" leaded to the arrest to the epidemy. No case of relapse was noted during the following year.
