An indigenous. Nevertheless, case of the West Nile virus was identified in mainland France for the first time this year. Moreover, According to the arbovirose monitoring bulletin broadcast Wednesday July 30 by Public Health France. Meanwhile, the case is located in the Provence-Alpes-Côte d’Azur region; The patient presented the first symptoms on July 15. Furthermore, Arboviroses are viral diseases transmitted by an arthropod. Therefore, In this case the mosquito. Meanwhile, “Aboriginal case” means that the patient did not contract the what west nile virus, first disease after a trip to a contaminated area within. However, 15 days before the occurrence of symptoms.
The West Nile or Western Nile virus was identified for the first time in 1937 in the West Nile district, Uganda. In addition, “He has historically been responsible for epidemics in Africa, the Middle East, Western Asia and Europe. He appeared in North America for the first time in 1999. he disseminated in a few years to the whole territory ”, explains Public Health France. In France, he is regularly detected around the Mediterranean.
How is the West Nile virus transmitted? – What west nile virus, first
Birds are the first virus reservoir but humans, horses and several other vertebrate species can also be contaminated. Transmission to humans is carried out by the bite of a mosquito. like Culex, itself infected after having an infected bird. “Man. the horse represent” epidemiological dead ends “for the West Nile virus because what west nile virus, first the amount of virus in the blood (viremic) is insufficient to infect the mosquito during a bite and thus allow the transmission of the disease”, continues the health agency.
What are the symptoms?
In almost 80 % of cases, the virus is asymptomatic. Symptomatic forms are characterized by:
- a brutal fever after 3 to 6 incubation.

But viral infection can be fatal mainly in senior adults ”, specifies the Pasteur Institute.
There is no specific treatment for the disease. Management is symptomatic.
The diagnosis can what west nile virus, first be confirmed by biological analyzes carried out in the blood and/or in the cerebro-spinal liquid (LCS). obtained by lumbar puncture.
No vaccine is available. The best way to protect yourself from the virus is the implementation of protective measures against mosquito bites: covering clothes. repellents, serpentine, electric diffusers, mosquito nets.
Collectively, it is necessary to fight against the larval lodges of mosquitoes.
