Observed mortality and that predicted in Reed Frost models. Representative examples are shown of observed cumulative mortality associated with OsHV-1 infection in different groups of oysters and cumulative mortality predicted in simple Reed-Frost models. A, B, C Individual segments of intertidal trays; D, E Intertidal baskets; F Upweller; G, H Subtidal (floating) baskets. The size of the population of susceptible oysters (S), the incubation period (IP) in days (d), the number of infected oysters that initiate the outbreak and the probability of effective contact p are shown for each model.
