Abstract

Fever of unknown origin is one of the most common causes of pediatric consultations and represents a diagnostic and therapeutic challenge for clinicians. In order to clinically and epidemiologically characterize pediatric patients with fever of unknown origin, a descriptive, observational, cross-sectional study was conducted in pediatric patients with prolonged fever of unknown origin. The population consisted of 62 patients discharged from the Provincial Pediatric Teaching Hospital “Hermanos Cordové” in Manzanillo, Granma, between January 1, 2022, and December 31, 2024. The predominant age group was over 11 years old, accounting for 45,1 %. Prolonged fever was present in 50 % of patients, and the classic form in 85,4 %. Fatigue was the predominant symptom in 77,4 % of cases. The most frequently used complementary test was the erythrocyte sedimentation rate (93,6 %). It was concluded that fever of unknown origin is more common in children older than 11 years and that the classic form predominates in more than two-thirds of cases. Prolonged fever is the most frequent pattern. Fatigue and weight los are the most commonly detected clinical manifestations. The most sensitive complementary tests are erythrocyte sedimentation rate and complete blood count, which often shows varying degrees of anemia.
