Is France Facing an Impending Dengue Epidemic?
In a concerning turn of events, the once-tropical disease dengue, transmitted by the tiger mosquito, is now posing a direct threat to mainland France. Are public health policies truly grasping the magnitude of this threat? According to Yannick Simonin, a virologist specializing in the surveillance and study of emerging viral diseases, and a professor at the University of Montpellier, the risk of a dengue epidemic in France is very real. Jerome Rochelle, the head of the outdoor environment department at the Regional Health Agency in Ille-et-Vilaine, echoes this sentiment. The tiger mosquito, the carrier of the virus, has established a presence in France, and the influx of tourists and delegations from around the world for the upcoming Olympic Games is raising concerns about the spread of this tropical illness, which can lead to hemorrhagic fevers.
The latest report from Santé Publique France, released this Wednesday, reveals a staggering increase in imported dengue cases, with 2,166 cases reported between January and April 30th. This is a stark contrast to the average of 128 cases during the same period over the past five years, causing alarm among health authorities. While Santé Publique France emphasizes that « no episodes of local transmission have been detected, » mosquito control operations led by Regional Health Agencies are intensifying, with recent efforts in Joué-lès-Tours, Toulouse, and Paris. It is crucial to note that dengue is not spread from person to person, but rather through the bite of the tiger mosquito. If the mosquito bites an infected individual, it becomes a carrier and can then infect other humans by biting them. Can this impending epidemic be contained? And if so, what measures need to be taken?
Originating from the tropical forests of Southeast Asia, this insect has shown adaptability to our urban environment. Should we view this as a symbol or a symptom of the perils of globalization and the climate crisis?

Stay informed and vigilant as we navigate through these uncertain times.
