Estimated probability of infection from the community and person-to-person transmission in households for individuals with a lower level of titer. Point and line indicates the point estimate and the 95% credible interval of the estimate, respectively. 95% credible intervals are constructed by using MCMC to fit the data with digraph model. a Estimated probability of infection from the community over the study period. b Estimated probability of person-to-person transmission in households, as a function of household size
