Mortality: The rise in mortality recorded since early January continued in week 7 and primarily affects older adults. This increase is observed across all regions. Nationally, since the start of the year, a preliminary estimate of winter mortality across all age groups shows that it is estimated to be 17% higher than expected mortality (compared to 2% during the 2013–14 season, and +10% and +12% during the 2012-13 and 2011-13 seasons, when a marked increase in mortality was also observed). These initial assessments should be treated with caution, as the current episode is not yet over and the data are not yet consolidated due to the usual delays in data transmission.
