The Risk Assessment of Norovirus Transmission in Food Establishments: Evaluating the Impact of Intervention Strategies and Food Employee Behavior evaluates the dynamics of norovirus transmission from ill or infected food employees in food establishments (restaurant setting) to ready-to-eat food and consumers during food preparation and also evaluates the impact of prevention strategies. A discrete event model was developed to study norovirus transmission from the soiled hands of ill or infected food employees and the impact of prevention strategies and their compliance on the prevalence of contaminated servings and the number of resulting infected customers.
This risk assessment is available via open access, ahead of print, in the Journal of Risk Analysis: An International Journal.
