Key Points

• Vector-borne diseases: 96 reports of suspected cases of chikungunya or dengue have been received since May 1, 2015. Four imported cases of dengue and one imported case of chikungunya have been confirmed (all acquired during travel to an endemic area). For this season, no locally acquired cases have been diagnosed to date in the region.

• Hospital and medical activity in the region: After very high activity during weeks 2015-28 and 29 (linked to the long weekend of July 14), SOS Médecins activity in week 30 returned to a more typical level for the period. Emergency room activity is fairly stable from week to week and remains slightly higher than in previous years during comparable periods.

• Heat Wave and Health Alert System (SACS): After a long period of intense heat, which did not trigger a Level 3 activation of the National Heat Wave Plan, temperatures dropped this week. Last week’s data thus continued to show the effects of the heat on the monitored indicators: in week 2015-30, emergency room visits for dehydration/hyponatremia/hyperthermia continued to rise. This week, approximately 100 emergency room visits for these reasons were recorded in the region, half of which involved people aged 75 or older.
