Key Points

Gastroenteritis Surveillance

• Gastroenteritis activity in the Grand Est region remains significantly higher than what was observed in previous years during the same period, both in emergency departments and among SOS Médecins associations.

• For both data sources, the overall trend shows a slight increase in activity in week 49 (December 5–11) compared to week 48. Some isolated fluctuations at the departmental level are occasionally observed.

• High activity is also observed within the Sentinelles Network, and the epidemic threshold for acute diarrhea has been exceeded for the past 4 weeks.

Bronchiolitis Surveillance

• Data for week 49 remain at high levels for both data sources and are comparable to previous seasons.

• Trends are opposite compared to Week 48: a steady increase for emergency departments and a marked decrease for SOS Médecins associations.

• The entire mainland (except Corsica) is in an epidemic phase

• An increase in RSV circulation is observed in the region.

Influenza surveillance

• The Grand-Est region is in the pre-epidemic phase

• Influenza viruses are beginning to be detected in virological data from the Nancy and Strasbourg University Hospitals. Type A viruses are predominant.

Monitoring of carbon monoxide poisoning

• During weeks 48 and 49, there were 12 incidents of carbon monoxide poisoning affecting 33 people.

Mortality surveillance

• According to available data, mortality rates for all age groups and among people aged 75 and older observed in recent weeks are consistent with seasonal norms.
