    Snippet: The transmissibility of a pathogen determines the intensity of interventions needed to achieve epidemic control [44] . The parameter most often used to quantify transmissibility is the reproduction number (R), the mean number of secondary cases infected by a single individual. This parameter has an intuitive interpretation: if R . 1, then the epidemic is likely to grow, whereas if R , 1, the epidemic will decline [44, 45] . The final attack rate .....
    Document: The transmissibility of a pathogen determines the intensity of interventions needed to achieve epidemic control [44] . The parameter most often used to quantify transmissibility is the reproduction number (R), the mean number of secondary cases infected by a single individual. This parameter has an intuitive interpretation: if R . 1, then the epidemic is likely to grow, whereas if R , 1, the epidemic will decline [44, 45] . The final attack rate ( proportion of the population infected) of an epidemic also depends on the value of R at the start of an epidemic (termed R 0 if the population has no immunity). R can be estimated from the incidence of reported cases, given knowledge of the serial interval distribution (i.e. distribution of time between symptom onset in a case and symptom onset in his/her infector; see §2b(iii)) [46] [47] [48] [49] .
