Key Points

Dengue, Chikungunya, and Zika

• As of August 19, two new episodes of local transmission of chikungunya were detected on the island compared to last week, bringing the total number of episodes reported since the start of the season to 4:

  • Grosseto-Prugna (2A): fourteen cases detected (no new cases compared to last week);

  • Ghisonaccia (2B): three cases detected (+1 compared to last week);

  • Porto-Vecchio (2A): 1 new case detected;

  • Bastelicaccia (2A): 1 new case detected.

• Furthermore, 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).

Heatwave

• The heat wave observed in Corsica last week has now ended. Both Corsican departments were placed on yellow alert on Sunday, August 10. Haute-Corse was then placed on orange alert on August 11, followed by Corse-du-Sud the next day. On August 18, Southern Corsica returned to the green alert level, followed by Upper Corsica on August 19.

• Regional activity for the iCanicule health indicator (including medical diagnoses of hyperthermia/heatstroke, dehydration, and hyponatremia) in emergency departments since the start of the heatwave was stable and low. SOS Médecins call volumes were very low. Nevertheless, heat-related activity had begun to increase as early as the beginning of June.
