Abstract	Objectives: To assess an outbreak of febrile syndrome in Punchao district through a clinical, laboratorial and entomological evaluation and to find out the factors associated to the occurrence of such outbreak. Materials and methods: Due to the report of three patients from Punchao, Huamalies (Huanuco) presenting with fever associated to headache, myalgia and postration, on the 41 st epidemiological week 2000; and because of an inusual presentation of feverish patients in the last week in such site; we decided to investigate the nature and characteristics of the outbreak. We define as case every patient with a time of illness less than 15 days with fever and one of these symptoms: headache, myalgias and postration and we started actively to look for these cases and to assess the presence of antiRickettsias antibodies in serum using IFI. We captured rodents and collected ectoparasites in houses (in rodents, domestic animals and humans), with the purpose of identifying Rickettsias using IFI, isolation and/or PCR. Results: We could not isolate the causal agent. The circulation of Rickettsia (positive serology) in humans (cases and no cases) and in rodents was confirmed. A greater presence of bad habits of cleanliness and inadequate conditions of basic sanitation in cases (in relation to no cases) and a decrease in the number of cases after the beginning of control measures, was evident. Conclusions: The evidences found allowed the identification of a typhus outbreak in Punchao; however, the determination of the involucrated species was not possible because the causal agent was not isolated.
