Epidemiological indicators show that the 2014–2015 flu season peaked during weeks 6 and 7 of 2015 in Brittany. The observed decline continued into week 14. The all-age mortality rate recorded by civil registry offices in week 13 was just below the alert threshold, unlike the 75+ age group, where it exceeded this threshold. In week 14, the number of deaths from all causes across all age groups and among those aged 75 and older is below expected levels and alert thresholds (these estimates should be interpreted with caution, as the data are not yet consolidated due to the usual delays in reporting).
