Seasonal influenza - Annual Epidemiological Report for 2015-16 season

As in previous seasons, influenza activity started in week 51/2015 and lasted until week 20/2016. Compared with previous seasons, primary care consultation rates for influenza-like illness (ILI)/acute respiratory infection (ARI) were similar in most EU/EEA countries. In almost all countries, the season was dominated by influenza A(H1N1)pdm09 viruses. EU/EEA influenza surveillance is based on weekly data reported to ECDC by sentinel general practitioners (in some countries also other physicians, such as paediatricians) and national influenza reference laboratories from week 40 to week 20 of the following year.
