Outline of Final Research Achievements |
Although outbreaks of norovirus infection (NVI) are frequently observed, the natural history of NVI has not been sufficiently understood. The present study aimed to quantify the unknown parameters of NVI transmission, such as the basic reproduction number (R0: the average number of secondary infection from a initial infection) and the infectivity of asymptomatic infection. Those parameters in NVI were analyzed through the comprehensive analysis of multiple NVI outbreak data and the use of mathematical modeling.
