Key Points

Mortality: Mortality during week 30 (July 24–30, 2017) is comparable to expected levels for this period across all age groups. The trend is the same at the national level.

Emergency department visits by vulnerable populations: Emergency department activity among people aged 75 and older and among children under 1 year of age remains close to expected levels, or even below them for this period.

Virology: The number of positive respiratory virus samples from the laboratories at the Bordeaux and Poitiers University Hospitals decreased in week 31 (17 positive samples). At the Poitiers and Bordeaux University Hospitals, the majority were rhinovirus/enterovirus (7 and 4 samples, respectively). No samples were positive at the Limoges University Hospital. At the Bordeaux University Hospital, a high number of enterovirus meningitis cases has been observed over the past 4 weeks (8, 10, 12, and 3 positive samples in the last 4 weeks), as well as 1 positive sample at the Poitiers University Hospital, consistent with data from emergency departments and the national epidemic.

Reportable Diseases: No cases of measles have been reported in the region since June 1. The increase in hepatitis A reports continues: 76% of cases are men, and 31% of cases are reported in Gironde. A cluster of cases linked to a common source (a meal at a restaurant) is currently under investigation in that department.

Allergies: Allergy activity observed by SOS Médecins associations is on the rise in week 31 in Nouvelle-Aquitaine. Current pollen levels (grasses, plantains, nettles, and mugworts) pose a low to very low allergy risk in the region.

Chickenpox: Chickenpox activity, according to SOS Médecins data, is close to what is expected for this time of year.

Chikungunya, Dengue, and Zika – Enhanced surveillance in Nouvelle-Aquitaine: in areas colonized by Aedes albopictus (departments 24, 33, 40, 47, and 64), 43 suspected cases have been reported. Among these, 4 cases of dengue and one case of Zika have been confirmed.

Heat-related illnesses: activity remains at typical levels for this time of year in both networks (OSCOUR and SOS Médecins). No heat wave is forecast in Nouvelle-Aquitaine over the next 5 days, according to Météo France.
