Data are presented as mean (95% confidence interval), unless otherwise stated. #: total winter excess was calculated as the difference between rates during virus active periods and reference periods multiplied by the average number of virus-active weeks per winter, i.e. 8.3 weeks for influenza virus and 7.7 weeks for RSV; ¶: no nonsignificant excess; +: nonsignificant excess.
