Understanding Norovirus Transmission and Symptoms

Norovirus is a highly contagious virus that can cause severe gastrointestinal symptoms, including nausea, vomiting, and diarrhea. It requires only a small amount of particles to trigger infection, making its spread particularly easy, especially in crowded environments like cruise ships and daycare centers. Due to its resilience to standard cleaning agents, preventing the spread of norovirus relies heavily on thorough handwashing and cleaning practices. While it generally causes significant discomfort for 24 to 48 hours, it poses a greater risk to young children and those with preexisting health conditions.
