Widespread Chikungunya Outbreak Prompts Health Emergency in French Island
French authorities have declared a public health emergency in the Indian Ocean island of La Réunion following a rapid outbreak of the Chikungunya virus, with nearly 6,000 new infections reported in just one week in March.
According to the “Réunion 1” TV channel, the total number of infections since the virus began spreading in 2024 has reached approximately 20,000 cases. In response, hospitals have activated the “White Plan,” an emergency procedure that allows for the rescheduling of non-urgent surgeries and the recall of medical staff from leave.
The cities of Saint-Denis in the north and Saint-Pierre in the south have experienced significant pressure on emergency services, amid warnings of overwhelmed hospital capacities and staff fatigue.
The regional health agency announced on Monday the launch of a vaccination campaign against the virus, with 40,000 vaccine doses distributed across the island.
Previous Outbreaks (2005–2006)
The first recorded infections are traced back to the island of Mayotte, where 12 cases were initially identified. Between 2005 and 2006, the virus infected around 260,000 people—over one-third of the island’s population—and caused more than 200 deaths.
Symptoms and Treatment of Chikungunya Fever
Chikungunya fever is caused by the Chikungunya virus. Symptoms include sudden onset of fever (lasting 2–7 days) and joint pain that may persist for weeks, months, or even years. The virus is transmitted through mosquito bites, mainly by the Aedes aegypti and Aedes albopictus species. While there is no specific cure, treatment focuses on relieving symptoms through medication, rest, and fluid intake.
