Figure 2

Generation time distribution for norovirus infections. Generation time is the time between onset of symptoms in successive case-patients. The histogram gives the relative frequency in norovirus outbreaks in Sweden in 1999 (25); the black line indicates the maximum-likelihood fit of the gamma distribution.
