Worldwide, rickettsialpox is most commonly associated with exposure to rodents in urban environments. Here, we present the case of a 47-year-old woman from Brantford, Ontario, with fever, eschar on the right leg, expanding erythema, and right groin lymphadenopathy. Early in infection, R. akari serology was negative (IgG &lt;1:64), but convalescent titre increased to 1:1,024. The patient did not travel outside of Ontario in the previous year. She denied any rodent or arthropod exposures in her home, but recently visited a friend\u2019s home infested with bats and mice. The patient was afebrile after treatment with doxycycline, with resolution of most clinical and laboratory findings in 5 days. This is the first rickettsialpox case reported in Canada and highlights the importance of obtaining convalescent serology to assist in the diagnosis of rickettsial infection.
