Leptospirosis en paciente en edad escolar

Introduction: leptospirosis is one of the most widely distributed zoonotic diseases in the world, however, its diagnosis can be difficult because the clinical manifestations are diverse. We present a school-age patient with leptospirosis, to promote early diagnosis in similar cases. Case presentation: 11-year-old male patient with fever, asthenia, adynamia, headache, edema in the lower limbs, choluria, myalgia in the gastrocnemius, as well as rash on the trunk and all four extremities. Different infections were ruled out, such as dengue, COVID-19, and syphilis. Given the persistence of symptoms for more than seven days, and due to the history of contact with domestic animals, leptospirosis was suspected. It was confirmed by elevation of specific IgM antibodies for Leptospira and a positive urine PCR result for Leptospira spp. 48 hours after starting antimicrobial treatment, the patient began to improve, reaching complete resolution. Conclusions: leptospirosis is a disease that has a variable clinical course, so it should always be considered as part of the differential diagnosis of patients with febrile syndrome.
