Mediterranean spotted fever in Algerian children.

Mediterranean spotted fever (MSF) is a potentially life-threatening zoonosis caused by Rickettsia conorii and transmitted by the brown dog tick Rhipicephalus sanguineus [1]. Although MSF is one of the oldest recognised rickettsioses, there have been few reports about this rickettsiosis in North Africa [1,2]. The present work on MSF cases occurring in children is a subset of a larger study conducted within all age categories.
