Norovirus is one of the most common causes of foodborne illness worldwide, and several factors contribute to its prevalence:
Only a small number of virus particles (as few as 18) are needed to cause infection, making it extremely easy to contract.
Norovirus spreads quickly through contaminated food, water, surfaces, and direct person-to-person contact. It can remain viable on surfaces for extended periods, allowing it to infect others.
Consuming foods or beverages contaminated with Norovirus is a common way of transmission, especially if food handlers are infected and practice poor hygiene.
Close contact, especially in crowded environments such as schools, cruise ships, hospitals, and nursing homes, facilitates transmission.
