TURNING LESSONS INTO ACTION: STRENGTHENING OUTBREAK MANAGEMENT THROUGH EXPERIENCE.

Abstract

Background: Norovirus is a highly infectious pathogen that causes acute gastroenteritis. Outbreaks can occur in healthcare environments, where swift transmission can happen if infection control protocols are not adhered to. In April 2024, a norovirus gastroenteritis outbreak transpired in a tertiary referral hospital's general medical ward where 32 individuals developed gastro symptoms, comprising both patients and staff. This outbreak continued as a result of poor compliance with infection prevention procedures. Actions: Upon identifying these epidemiologically-linked cases in the ward, immediate infection control measures were enacted. These encompassed improved hand hygiene and efficient clinical and environmental sanitation. Staff education was enhanced through daily ward huddles, immediate feedback on infection control practices, and real-time audits to verify compliance. Supplementary training emphasised the correct utilisation of personal protective equipment (PPE) and compliance with outbreak protocols. Leadership involvement and ongoing surveillance supported outbreak management initiatives. Result(s): In January 2025, two new epidemiologically-linked norovirus cases were identified in the same ward. As a result of the aforementioned interventions, staff education was sound and there was stronger compliance with infection control practices. No further transmission was reported beyond the initial two confirmed cases, and the outbreak was declared resolved after satisfying infection control clearance criteria. Conclusion(s): This outbreak underscores the importance of prompt detection, rigorous compliance with infection control protocols, and optimisation of staff training and engagement. Enhancing adherence to hand hygiene, efficient sanitation, and immediate feedback systems are crucial to minimise future outbreaks in healthcare environments.
