Since September 1, 2012, 23 deaths due to CO poisoning have been reported to the surveillance system out of 589 incidents involving 1,908 people.

• The decrease in the number of poisoning incidents observed during weeks 2012_S52 and 2013_S01 (54 incidents) compared to the same period last year (77 incidents) is mainly due to particularly mild weather conditions in recent weeks.

• A mass CO poisoning incident occurred in a restaurant linked to the use of a large number of charcoal stoves on tables for fondue cooking, exposing 61 people to CO fumes, three of whom were taken to a hospital emergency department.
