Fig. 5From: Reconstructing the household transmission of influenza in the suburbs of Tokyo based on clinical casesLikelihood curves for the two influenza types. a. Type A and b. type B are shown with respect to the number of secondary cases in a household as a function of the force of infection (FOI) coefficient λ0. The likelihood values are determined by simulation runs with different values of λ0 and Δλ0 = 0.005; optimal values of λ0 are 0.065 for A and 0.015 for BBack to article page
