Three cases of autochthonous infections by the West Nile virus due to mosquitoes (or West-Nile) have been identified in the PACA region.
Mosquito: West Nile virus: 3 cases identified in Provence-Alpes-Côte d’Azur
According to a press release published by the Regional Health Agency (ARS) of Provence-Alpes-Côte d’Azur (Paca) on August 18, 2023, three cases of indigenous West Nile virus infections have been identified in the region. These cases were transmitted by mosquitoes. And took place in Antibes in the Alpes-Maritimes, Gardanne in the Bouches-du-Rhône and Toulon in the Var. The ARS is collaborating with the regional unit of Public Health France to investigate possible sources of contamination. Measures have been put in place to monitor and control mosquito populations in affected areas.
Understanding West Nile Virus Infection
West Nile virus, transmitted by Culex mosquitoes, is a common infection in France. They are infected by feeding on infected birds. Other arboviruses such as dengue, chikungunya and Zika are transmitted by the Aedes mosquito. However, humans and horses are considered “accidental hosts” of West Nile virus. This means that there is no direct person-to-person transmission of the virus by mosquitoes. This limits the risk of epidemics.
Most cases of West Nile virus infection are asymptomatic in humans. However, some patients may have flu-like symptoms. Such as fever, headache and muscle aches. These symptoms may then be accompanied by a rash. Neurological complications can also occur, but they are rare.
Mosquito Control Measures
They are vectors of various diseases, including West Nile virus. To prevent diseases that mosquitoes transmit, it is important to take steps to control mosquito populations.
An effective way to control them is to eliminate their breeding sites. Mosquitoes lay their eggs in standing water, so removing standing water around homes and businesses is essential. This can include emptying outdoor water containers, cleaning gutters and fixing leaky pipes.
Another way to control mosquitoes is to use insecticides. Mosquito control agencies can use insecticides to kill adults and their larvae. However, it is important to use these chemicals responsibly. As well as follow the instructions carefully to avoid harm to humans and the environment.
In addition to these measures, individuals can protect themselves from bites by wearing long-sleeved shirts and pants. Also using mosquito repellents. And finally, avoiding outdoor activities during peak mosquito hours.
Recent cases of West Nile virus infections in Provence-Alpes-Côte d’Azur are a reminder of the importance of mosquito control and prevention. By taking appropriate measures to control populations and protect ourselves from their bites, we can reduce the risk of mosquito-borne diseases and promote public health.
