title: [Fatal case of rickettsiosis in a toddler from southeastern Mexico].
abstract: Rocky Mountain spotted fever is a disease caused by Rickettsia rickettsii, a bacteria transmitted by infected ticks. It is characterized by fever, exanthema, arthralgias and myalgias; but sometimes its clinical presentation is non specific. Due to its similarities with other exanthematic diseases like dengue or chikungunya, Rocky Mountain spotted fever is not a first line diagnosis, even though countries like Mexico show the ecologic and socioeconomic characteristics that favor its transmission, with a 30% mortality rate among pediatric patients. This mortality rate has been associated to a delayed diagnosis and therapy, due to a poor knowledge among physicians regarding this disease; this favors the occurrence of atypical and fulminant cases. The objective of this work is to describe a fulminant case of Rocky Mountain spotted fever, expecting that this disease could be later considered among the differential diagnosis which could directly impact its mortality rate.
