Latest news on Influenza Season 2016/2017
Influenza season 2016/2017 in the northern hemisphere began in November and is expected to keep increasing over the coming weeks. Influenza viruses are estimated to affect 5-10% of the world’s population, causing 250.000-500.000 deaths each year (WHO). There are also many asymptomatic cases.
So far it seems that with the beginning of the current season influenza cases have been increased compared to first weeks of 2015/2016 season (Figure 1).
In the 2016/2017 influenza season laboratory data signify influenza A(H3N2) to be the main subtype circulating. Simultaneously an equal amount of influenza A positive cases without subtyping is present.
Influenza B prevalence is so far low, which is typical after a year in which influenza B was circulating widely.
