Key Points

Dengue, Chikungunya, and Zika

• Update as of August 13 on the two episodes of local transmission of chikungunya detected in Corsica:

  • Grosseto-Prugna (Southern Corsica), fourteen cases detected (+1 compared to last week);

  • Ghisonaccia (Haute-Corse), two cases detected (+1 compared to last week).

• In addition, since the start of enhanced surveillance (May 1), 3 imported cases of dengue and 3 imported cases of chikungunya have been confirmed in Corsica (no new cases compared to last week).

Heat Wave

• A heat wave is currently underway. Both Corsican departments were placed on yellow alert on Sunday, August 10. Haute-Corse was then raised to orange alert on August 11, followed by Corse-du-Sud on August 12. These high temperatures are expected to persist until at least midweek, or possibly into the weekend.

• Emergency room activity for heat-related conditions appears to have risen slightly over the past three weeks (share of activity) and is higher than expected. The percentage of hospitalizations for heat-related conditions and the share of activity due to heat-related illness remain stable compared to last week. At SOS Médecins, only one diagnosis of a heat-related condition was made in week 32.
