ABSTRACT

Introduction: There are different genera and species of the family Ricketiciaceae that they pose a threat in humans and they are often transmitted by ectoparasites staying in primary guests. These organisms of the genus rickettsia are grouped into the maculous fever, typhus, among others, being a health problem in the northamerica.
Material and Methods: A retrospective review of cases of rickettsiosis in Baja California was made. They were considered to be variables: Age, sex, place of origin, as well as clinical signs presented with emphasis on its classification on suspected,probable and confirmed cases and laboratory studies that include hematic biometry, liver function tests in addition to testing Elisa Felix Weil, and received treatment.
Results: Confirmed in 258 patients diagnosisof rickettsiosis, by the method of Weil Felix confirmed by Elisa ; in 275 casesthe causative agent was by rickettsia rickettsi and in three cases by rickettsia prowazeki. 96%of all cases in the city of Mexicali, 42 per cent were male and 58% female. The signs and symptoms were: Fever, headache, nausea, abdominal pain, vomiting, myalgia and arthalgia, meningeal signs, seizures and exantema. The cases were treated with doxycycline 100 mg every 12 hours in adults, children over the age of 9 at a rate of 5 mg/kg/da y every 12 hours, chloramphenicol 50 mg/kg/day, clarithromycin 15 mg/kg/day to every 12 hours, ciprofloxacin 750 mg every 12 hours in adults, there was a good response to treatment. The total deaths of suspected cases was 13 and 8 deaths confirmed by the CDC. The rate of morbidity of 2.9% compared with geographical areas close to the state less than these was that other entities reported mortality from 22 to 33.5%.
Conclusions: The rickettsiosis is a condition that did not had been suspected in years in Baja California this reflected deficiencies in handling delayed treatment, Mexicali confirmed 100% of the cases, clinical manifesta tions of poor prognosis the rash and thrombocytopenic purpura are considered.
