Nevertheless, since week 51, the etiological role of influenza A/H1N1 in ARI has been rising
with a clear upward trend since week 2, in accordance with the development of morbidity.
The higher detection of RSV has been recorded from the 5th week. The results presented in
Fig. 2 are based on the sentinel and non-sentinel data collected by the NRL and on data
reported by the collaborating laboratories, so this graph illustrates the trend in influenza A/B,
non-influenza and RSV infection.
Fig. 2 : Percentage of influenza A and B, RSV and non-influenza viruses on the etiology of
ARI in the Czech Republic, from week 40/2018 to week 6/2019. Whole-country data.
The morbidity expressed by the ARI curve shows an autumn dynamic increase (caused
mainly by non-influenza viruses), a traditional Christmas drop, and a sharp rise due to the
onset of the epidemic in the first weeks of 2019. It is probable that the 2018/2019 influenza
epidemic will be less widespread as compared to the seasons 2017/18 and 2016/17.
