Bc, bacterial concentration; IF%, human infectious fraction of target organism; M, model; Ex, exposure; R, response. *For the QMRA analysis, the Minitab® 19 statistical software package was used to calculate the distribution of each target pathogens’ concentration based on the EMA-qPCR and conventional qPCR data (Figure 1).
