An outbreak of Ralstonia insidiosa in hospitalized children

Abstract

Introduction: Healthcare-associated infections (HAIs) pose significant public health challenges, increasing patient morbidity, mortality, and healthcare costs. This study analyzes an outbreak of Ralstonia insidiosa in children admitted to a pediatric referral hospital, focusing on implemented control and prevention measures. Methods: A prospective observational study was conducted during the outbreak, emphasizing control measures in a pediatric hospital. Results: Eighteen cases were reported over 19 epidemiological weeks, with an attack rate of 8.79% in pediatric intensive care units (PICU) patients and 1.76% of those in other wards. The affected children were primarily those hospitalized for over 14 days, with invasive devices, admitted to PICU, and having underlying conditions. Symptoms included vomiting, fever, and cough. Outbreak control was achieved through epidemiological and antimicrobial surveillance measures. Conclusions: Ralstonia insidiosa is an emerging nosocomial pathogen associated with risk factors such as invasive devices and prolonged PICU stays. Effective control measures, leveraging available resources, can mitigate outbreaks.
