Today, it has been reported that several cases of West Nile virus infection have been found in France for the first time that were contracted within the country. This alarming revelation has experts warning about the increase in dangerous mosquito species in the country, which is directly linked to the ongoing climate crisis.
As of the beginning of September, there have been a total of eight possible or confirmed infections. In addition, four cases of infection with the Usutu virus have been reported in the south-west of France. The Usutu virus can lead to serious illnesses, including meningitis.
Mosquito specialist Anna-Bella Failloux explained to France Info that this increase is likely due to improved detection methods. She stated, “It does not necessarily mean that there are more mosquitoes than before, but we are certain that the climate crisis is contributing to the explosion of certain mosquito species and therefore the diseases they carry.” The higher temperatures caused by the climate crisis enable mosquitoes to reproduce at a faster rate. It is important to note that the West Nile and Usutu viruses are spread by mosquitoes other than the well-known tiger mosquito, which has already been on the rise for some time and spreads diseases like dengue fever.
While these mosquitoes have been present in the Mediterranean region for some time, they are now expanding their territory and establishing themselves in other parts of France, such as the Atlantic coast. The Local reports that control operations are being conducted, but the issue lies in the fact that mosquitoes can quickly develop resistance to control methods.
Currently, French authorities do not perceive the Usutu virus as a significant threat, unlike the West Nile virus. However, the situation warrants close monitoring and proactive measures to prevent further spread of the virus and protect public health.
The National Food and Supply Authority (NVWA) is urging holidaymakers to thoroughly check their cars and caravans for mosquitoes before traveling back home. Campers, in particular, should inspect flower pots, trays, or watering cans that may have accumulated rainwater. These stagnant water sources can potentially contain tiger mosquito eggs, which can hatch later. Taking these precautions can help reduce the risk of mosquito-borne diseases and contribute to public health safety.]
