Core Viewpoint - The article emphasizes the importance of scientifically handling vomit, especially in collective settings like schools, nurseries, and nursing homes, to prevent the spread of Norovirus, a highly contagious pathogen responsible for acute gastroenteritis [1][16]. Preparation Steps - Evacuate surrounding individuals to a safe and clean area [1]. - Notify trained personnel, such as cleaning staff and school nurses, to handle vomit and the surrounding environment [3]. - Wear appropriate protective gear, including disposable gloves, masks, isolation gowns, shoe covers, and hats, with eye protection if necessary [4]. - Open windows for ventilation before cleaning, ensuring both windows and doors are opened to enhance air exchange [4]. Disinfection Process - The core disinfection process involves three main steps: covering the vomit, disinfecting the surrounding area, and cleaning [6]. - Step 1: Use disposable absorbent materials soaked in a chlorine disinfectant with a concentration of at least 5000 mg/L to cover the vomit, allowing it to sit for 3 minutes before transferring it to a disinfectant solution for 30 minutes [7]. - Step 2: Disinfect the surrounding area by either spraying or wiping with a chlorine disinfectant at a concentration of 1000 mg/L, ensuring a contact time of 30 minutes [9]. - Step 3: After the disinfection time, clean the area with water [11]. Final Steps - Personal hygiene and health monitoring: Dispose of protective gear without contamination and wash hands thoroughly [12]. - Waste disposal: Package disinfected vomit in plastic bags and treat it as regular waste, or as medical waste if conditions allow [12]. - Record keeping: Document the disinfection process, including the type of disinfectant, concentration, contact time, location, and personnel involved [13][14].
