French authorities have reported two recent deaths from chikungunya, a mosquito-borne virus causing high fever and intense joint pain, on the island of La Réunion. The deceased were both elderly—ages 86 and 96—and one had pre-existing health conditions, according to the regional health agency.

Since August 2024, the island has seen more than 8,500 cases, with nearly 2,900 infections recorded in just one week this March. Over 70 individuals required emergency care.

In response, authorities have launched an aggressive campaign to control mosquito populations, deploying 150 health workers and municipal staff to fumigate affected areas daily. Vaccination is also being encouraged for those at higher risk.

The chikungunya virus, which translates to “to become contorted” in Kimakonde (describing the painful posture of sufferers), is transmitted by Aedes mosquitoes, the same species that carry dengue and Zika.

Why This Matters for Los Angeles County

La Réunion’s outbreak offers a cautionary tale for areas like Los Angeles, where Aedes mosquitoes are well established. With global travel and warming temperatures, the potential for local chikungunya transmission increases—especially if infected travelers return to mosquito-active regions.

We urge residents to eliminate standing water, use insect repellent, and stay informed about travel-related mosquito risks.
