Table 4. Values for the specific reproductive numbers for children under 15(respectively, R _C and R _A) and the degree of assortativity d_R for the three strains circulating averaged over all seasons for which estimates are possible (i.e., for seasons where a significant epidemic occurred).

R A	1.0 [0.8–1.4]	1.1 [0.8–1.5]	1.1 [0.8–1.4]
