[Tinea corporis].

Between February 2011 and April 2012, an outbreak caused 55 episodes of Tinea corporis in a Berlin kindergarten. According to the case definition Tinea corporis was confirmed in 2 cases, 16 cases were dermatologically probable, 24 cases were suspicious, whereas 13 cases were viewed as improbable. 48% (n=32/67) of all children had at least one episode of disease. Of those aged 4-6 years 76% (n=29/38) were affected, compared with 10% (n=3/29) of those younger than 4 years. Despite comprehensive hygienic measures being taken, the outbreak could not be quickly controlled. To stop the outbreak the immediate cooperation of public health service and medical staff, kindergarten employees, parents and children was necessary. The timely involvement of dermatologists along with a uniform treatment approach turned out to be of major importance. The recommended long treatment duration over several weeks affected adherence to treatment. Overall, the extended treatment in the kindergarten of affected skin areas of children proved to be the most effective measure for the control of the outbreak.
