Fig. 2: Infection probability and its determinant among six epidemics.
From: Reconstructing antibody dynamics to estimate the risk of influenza virus infection
A Estimates of infection probabilities for children, younger adults and older adults in the six epidemics in our study period. The overall infection probability and infection probability for individuals with pre-epidemic titer of <10 are plotted to show the protective effect of pre-epidemic titers. Points and vertical lines are used to show the mean and corresponding 95% credible intervals of the estimates based on our estimation approach fitted to data with 2353 individuals. B The protection associated with 2-fold increase in HAI titers in epidemic 2–6. Points and vertical lines are used to show the mean and corresponding 95% credible intervals of the estimates based on our estimation approach fitted to data with 2353 individuals. C The pre-epidemic HAI titer distribution for children and adults in the six epidemics. Funnel plots are used to show the distribution. Points and vertical lines are used to show the mean and corresponding 95% credible intervals of the estimates based on our estimation approach fitted to data with 2353 individuals. D Model estimate of the age-relative susceptibility for six epidemics. Points and vertical lines are used to show the mean and corresponding 95% credible intervals of the estimates based on our estimation approach fitted to data with 2353 individuals.
