• The epidemic lasted 12 weeks, peaking during the last week of December 2016.

• Although longer in duration than in the two previous seasons, the characteristics of the epidemic in terms of healthcare utilization (age distribution, proportion of cases, and hospitalization rate) are similar to those of the last two seasons.
