An investigation of Norovirus gastroenteritis outbreak epidemic caused by mountain spring water contamination

Abstract

Abstract
This study investigates a norovirus gastroenteritis outbreak linked to contamination of mountain spring water. Epidemiological surveys, environmental sampling, and laboratory testing were conducted to identify the source and transmission routes of the outbreak. Results confirmed norovirus presence in the mountain spring water, which was used for drinking and domestic purposes by the affected population. The outbreak primarily affected children and young adults, with symptoms including acute diarrhea, vomiting, and abdominal pain. Contributing factors included inadequate water treatment and poor sanitation practices. The investigation highlights the critical need for proper water source protection, timely detection, and community health education to prevent waterborne norovirus outbreaks in rural areas.
