Investigation and analysis of an outbreak of acute gastroenteritis due to Campylobacter jejuni

Abstract

Objective: To investigate the epidemiological characteristics, source, and transmission route of an acute gastroenteritis outbreak caused by Campylobacter jejuni, and to provide recommendations for prevention and control.
Methods: A field investigation was conducted following reports of increased cases of acute gastroenteritis. Clinical samples from patients and environmental samples from suspected sources were collected and tested for Campylobacter jejuni using culture and molecular identification methods. Epidemiological data were analyzed to identify the outbreak’s scope, risk factors, and transmission pathways.
Results: The outbreak affected X individuals, with symptoms including diarrhea, abdominal pain, and fever. Laboratory confirmation identified Campylobacter jejuni as the causative agent. Epidemiological analysis suggested a common source related to contaminated food or water. Control measures including sanitation improvement and health education were implemented, effectively halting the outbreak.
Conclusion: Rapid identification and comprehensive epidemiological investigation are essential in managing Campylobacter jejuni outbreaks. Strengthened food and water safety practices are critical to prevent future occurrences of acute gastroenteritis caused by this pathogen.
