ABSTRACT
Background: Rocky Mountain spotted fever (RMSF) is
a disease spread by an infected tick and it is lethal if
patient is not treated on time. Symptom similarities with
other exanthematous diseases may delay the
diagnosis, which leads to its mortality.
Clinical case: We show the lethal case of a patient
with medical record of high blood pressure and no
history of travel, who lived in Sonora, Mexico. At the
beginning, it was suspected that the patient had a
dengue virus infection, which was confirmed positive
by an ELISA test. Patient’s rapid deterioration, multiorganic
failure and the characteristics of her
exanthema led to the suspicion of the presence of
RMSF. We started doxycycline treatment; however,
patient died after seven days of evolution. It was
confirmed a co-infection of Rickettssia spp. and
dengue virus.
Conclusion: In rickettsial endemic zones, treatment
with doxycycline should be employed in patients with
similar symptoms, even though there is evidence of the
presence of other etiologic agents.
