Epidemiological models Incubation-enhanced spreading
PROFESSOR: So in the majority of cases of indoor spreading that occur over the space of hours or even a few days, the Wells-Riley model of slow incubation where the number of infectors is held constant at the initial value, is a reasonable approximation. For COVID-19, the incubation period is estimated to be on the order of several days. For example, a number of 5.5 days is often quoted as an estimated mean incubation period. On the other hand, in some cases there are spreading events that involve people interacting over much longer periods of time than that. A famous example, which is a little bit longer than the time of incubation, is the case of the Diamond Princess cruise ship, which was quarantined in Yokohama Port, Japan in early 2020 when it was detected that there were a number of cases onboard. The exact number wasn't known because they hadn't tested the entire population, but there were several cases. And so they decided to quarantine the ship for 12 day...
