Chikungunya epidemic in La Reunion: 4,000+ new cases in past week

The chikungunya epidemic is now widespread throughout the country and continues to spread

In a follow-up on the chikungunya epidemic in La Reunion Island, the Agence Regionale de Sante La Reunion (ARS La Reunion), reported 4,156 new indigenous chikungunya cases during the week ending March 16, a 16% increase compared to the previous week.

Since the outbreak began in August 2024, 13,594 cases have been reported, with the vast majority being reported since the beginning of the year.

The southern and western municipalities are the most affected. Le Tampon remains the most affected municipality.

The number of cases has increased sharply to: The Possession, Saint Andrew, Saint-Paul and Saint Suzanne.

Several cases have been reported in newborns and infants, some requiring intensive care. While these cases are consistent with an expected evolution of the epidemic and current knowledge of the disease, their severity underscores the importance of strengthening preventive measures.

Emergency department activity is on the rise, rising from 78 admissions the previous week to 128 during the week of March 10-16. Hospitalizations lasting more than 24 hours totaled 82. This marked increase is partly explained by a catch-up in reports from certain hospital departments.

In the majority of cases, people hospitalized have comorbidities, but hospital services also treat pregnant women for chikungunya monitoring at the end of pregnancy and young children in pediatrics.

To date, 15 serious cases have been reported, including eight adults and seven newborns and infants. Last week, health authorities announced two virus-related deaths, among elderly people, one of whom had comorbidities.

The mobilization of all Reunion Islanders is essential in the fight against the current chikungunya epidemic. More than ever, preventive measures are the best way to protect ourselves and the most vulnerable.

Pregnant women, especially in the third trimester, and infants should be particularly vigilant; it is essential to use suitable repellents and sleep under mosquito nets.

The ARS and the prefecture are launching a new communication campaign this week to remind everyone of their responsibility in the fight against chikungunya by adopting the right actions:

• Protect yourself against mosquito bites

• Eliminate places where mosquitoes can lay their eggs

• Consult a doctor if symptoms occur
