Exploring Acute Febrile Illness in Children: Clinical Characteristics and Diagnostic Challenges

Background Pediatric febrile illnesses are a major cause of hospital admissions and are often associated with significant morbidity and mortality. These illnesses pose a diagnostic challenge to both clinicians and laboratories. This study aims to explore the clinical characteristics of acute febrile illness in children and examine the effectiveness of various diagnostic techniques. Methods This prospective study was carried out at the Mahatma Gandhi Memorial Hospital, Warangal, India, from January 2020 to October 2022. It included children aged one month to 12 years. Results Out of 245 identified cases, 195 met the inclusion criteria. This study found that 18 patients (9.23%) suffered from serious bacterial infections (SBIs). In 63 patients (32.20%), the source of infection remained unidentified. Among those with SBI, UTIs were the most frequent. Bacteremia was identified in 2.5% of the patients. Conclusion SBIs were identified in 18 hospitalized children (9.23%), with UTIs being the most common SBI in children aged one to 36 months. Children in this age group presenting with toxic symptoms should be thoroughly evaluated for SBIs. The study also observed a higher prevalence of Gram-negative bacteremia compared to Gram-positive cases.
