Flu epidemic ongoing in La Réunion

The flu epidemic continues in La Réunion, with the Regional Health Agency (ARS) reporting ongoing active circulation of the virus. Emergency rooms recorded 199 visits for flu-like symptoms during the week of October 5 to 11, the highest level since the start of the epidemic.

Youth most affected in La Réunion

Less than 15 years old accounted for 75 percent of emergency room visits for flu-like symptoms in La Réunion. Hospital pressure remains high, with daily emergency room visits peaking at over 120 in the North and 200 at the South CHU.

Hospitalizations and severe cases decline

Hospitalizations following emergency room visits for flu-like symptoms have decreased, from 30 at the end of September to 13 at the beginning of October.

Early flu signs in Mayotte

In Mayotte, the circulation of flu viruses began earlier than usual. The first signs of the 2026-2027 season were detected as early as the end of July last year. From October 5 to 11, 17 positive flu samples were recorded, with a high positivity rate of 26.9 percent.

Mayotte remains in pre-epidemic phase

Despite the early signs of flu circulation, Santé publique France maintains Mayotte in the "pre-epidemic" phase. A reagent shortage at the Mayotte Hospital Center (CHM) laboratory limited virological analyses, affecting the representativeness of the data and preventing confirmation of sustained viral circulation.

Respiratory disease trends in Mayotte

Beyond the flu, health indicators in Mayotte show persistent circulation of respiratory diseases. From October 5 to 11, low acute respiratory infections represented between 2.5 percent and 4 percent of emergency room visits, with higher figures in reference medical centers and dispensaries. Health authorities emphasize the importance of preventive measures and recommend the flu vaccine for high-risk groups.
