Key points
- During the 2016/2017 winter season, the influenza epidemic in the Netherlands lasted for 15 weeks.
- This was longer than the nine-week average duration of epidemics in the twenty previous seasons.
- Influenza subtype A(H3N2) was the dominant influenza virus throughout the season.
- In general, baseline natural immunity against A(H3N2) is relatively low among the elderly:
* Indeed, the number of patients older than 65 years, who visited a general practitioner (GP) for influenza-like symptoms, was higher than last year when influenza A(H1N1)pdm09 predominated.
* In nursing homes, the number of patients with influenza-like symptoms was also high.
