Chikungunya, Dengue, and Zika

• Since the start of enhanced surveillance (May 1), 24 imported cases have been identified in the region: 18 cases of chikungunya and 6 cases of dengue.

• The chikungunya outbreaks in Réunion (and more broadly in the Indian Ocean) and the dengue outbreaks in Guadeloupe are having a significant impact on surveillance in mainland France.
