Réunion Island is grappling with an escalating chikungunya epidemic, prompting increased mobilization efforts from authorities. Teh latest data reveals a meaningful surge in cases, underscoring the urgent need for enhanced preventative measures and vector control strategies.
Alarming Rise in Chikungunya Cases
The spread of chikungunya in Réunion has reached a critical point. The week of March 3-9 saw 2,888 new cases, prompting authorities to elevate the situation to Level 4 of the Orsec plan on March 14. This escalation reflects the consistently rising numbers and the need for a more robust response.
During the week of February 24 to March 2, 1,766 cases where recorded, marking a significant increase in infections. The southern region of the island remains the most affected, with the commune of Tampon particularly impacted. However, all areas of Réunion are now experiencing the effects of this outbreak.
since August 2024, a total of 8,749 chikungunya cases have been registered, with 8,600 of these occurring since the begining of the year. This rapid increase highlights the severity of the current epidemic.
Heightened Crisis Management
On January 13, authorities declared a “low intensity” outbreak of chikungunya, activating Level 3 of the crisis management system targeting arboviruses.This initial response has now been amplified to Level 4, indicating a more thorough and coordinated effort to combat the spread of the disease.
The Prefect of Réunion Island, Patrice Latron, announced on Monday, January 13, that the island is facing a “low intensity” outbreak of chikungunya, prompting the activation of Level 3 of a crisis management system targeting arboviruses.
Adapting Vector Control Strategies
in response to the increasing number of cases and their widespread distribution,authorities have adapted their vector control strategy. The focus is now on targeted interventions around isolated cases to prevent the formation of new outbreak clusters. This involves eliminating breeding sites to reduce the risk of transmission.
Actions are also being implemented in neighborhoods with grouped cases or emerging clusters to prevent active outbreaks. Public awareness campaigns and sanitation operations are being conducted in areas where active outbreaks are present.
With the support of municipalities and inter-municipalities, vector control teams have been reinforced by recruiting 79 temporary workers for field operations. An engineer specializing in intervention planning has also been brought in to support the effort.
Currently, 150 agents are deployed daily, addressing 120 to 140 areas, each encompassing about ten houses. Approximately 700 home visits and 400 insecticide treatments are carried out each day. Since August 2024,20,937 homes or apartments have been visited,and 5,587 breeding sites have been eliminated.
Community Involvement is Crucial
The public is urged to enhance preventive measures, such as eliminating standing water around homes, plants, and gutters, and covering cisterns and water reserves with fabric.
Bulky items should only be placed outside the evening before or on the day of collection, as waste can serve as breeding grounds for mosquitoes. Protecting oneself from mosquito bites by applying repellents, installing mosquito nets, and wearing long, light-colored clothing is also essential.
key Preventative Measures
- Eliminate standing water around homes
- Cover water storage containers
- Use mosquito repellents
- Install mosquito nets
- Wear long, light-colored clothing
The fight against the chikungunya epidemic in Réunion requires a concerted effort from both authorities and the community. By working together and implementing these measures, the spread of the virus can be contained, and the health of the population can be protected.
