This study reports the first urban human case of Rocky Mountain spotted fever caused by Rickettsia rickettsii, in Costa Rica. An 8-year-old female who died at the National Children's Hospital 4 days after her admission, and an important and significant observation was the presence of an “eschar” (tache noire), which is typical in some rickettsial infections but not frequent in Rocky Mountain spotted fever cases.
