Primer caso urbano de rickettsiosis por Rickettsia parkeri (cepa Atlantic Rainforest) en Mérida, México

We report the first case of rickettsiosis by <i>Rickettsia parkeri</i> in an urban area in Mexico. Infection is considered mild to moderate, but it is unusual in urban environments. Medics should be concerned about the clinical manifestations associated with tick bites, particularly when lymphadenopathy is present.
