The island faces ongoing concerns as the mosquito-borne disease remains a public health challenge.
Twenty years after a major outbreak, the Chikungunya virus continues too circulate in Réunion, despite efforts to combat it, including trials of sterile male mosquitoes. Concerns have been raised about the ongoing presence of the virus.
The first recorded case in Réunion was on Feb.22, 2005, according to archives. Initial assessments by authorities suggested the disease was mild and that the southern winter would curb the mosquito population, thus limiting transmission. However,some observers believe the gravity and consequences were underestimated at the time,a situation they feel is mirrored in current approaches.
Looking back, a senatorial report highlighted that between march 28, 2005, and Jan. 1, 2006, the surveillance system reported 12,000 cases of Chikungunya infection, equating to an attack rate of 9 per 1,000 inhabitants. The epidemic initially peaked with 450 cases during the week of May 9-15, before declining from July onward. The arrival of the southern winter was thought to have impacted the virus’s spread.
In January 2006, a resurgence of the epidemic led to a week-long postponement of the school year to allow for mosquito control operations in schools.
Exceptional Measures Urged
Officials emphasized the need to restore a permanent prophylaxis service in Réunion, equipped to handle significant health issues. This call followed the mobilization of entomological and epidemiological teams, along with an information mission by the Social Affairs Committee.
A government mission, including the Director General of Health and the Director of the Institute of Health Surveillance (InVS), visited the island. Later, the Minister of Health advocated for a global strategy for the fight against the epidemic.
faced with the epidemic’s scale, French doctors’ associations requested medical reinforcements, while local deputies sought a parliamentary commission of inquiry.
In response, resources were allocated, including 300 soldiers to assist with mosquito control. The Red Cross distributed 50,000 mosquito repellent kits to vulnerable populations and children. High-level visits included the Minister of Overseas, the Minister of Tourism, the Prime Minister, and a delegation of experts from the World Health Association (WHO).
Medical professionals at the time expressed uncertainty regarding the long-term effects of the disease. The question remains: What are the long-term consequences 20 years later?
As the epidemic possibly expands, questions arise whether parliamentarians will address the situation and urge the government to implement exceptional measures. There are calls for the fight against the virus to become a national priority, especially after the damage caused by Cyclone Garance.

Initial assessments by authorities suggested the disease would be relatively mild, with the southern winter anticipated to reduce the mosquito population and thus limit the spread of the virus. However, some observers feel the severity and consequences were initially underestimated, a situation they beleive is mirrored to some extent in current approaches.
How Many Cases Were Reported During the Initial Outbreak?
Between March 28, 2005, and January 1, 2006, the surveillance system reported 12,000 cases of Chikungunya infection. This corresponded to an attack rate of 9 per 1,000 inhabitants. The epidemic peaked during the week of May 9-15, with 450 cases before starting to decline from july onward.
what Measures Were Taken During the 2005-2006 Outbreak?
