The West Nile virus, which is circulating in the Camargue, and is transmitted via mosquitoes. Two horses have died, according to health authorities. The virus can be transmitted to humans, most of the time without serious consequences. But we must be very vigilant.
The departmental directorate for the protection of populations (DDPP) is warning of a “very strong suspicion of West Nile virus infection for three horses in the communes of Mauguio, Lattes and Lansargues, two of which died, thus testifying to the circulation of the virus in Camargue”.
This is not the first time that the virus has been introduced to the department. West Nile virus infection is transmitted by mosquitoes that become infected by biting infected wild birds. Horses, and sometimes humans, are “accidental hosts” that can be infected by this virus when bitten by infected mosquitoes but cannot transmit the virus themselves.
Human infection may be asymptomatic
According to the Hérault prefecture: “The disease manifests itself in equines either in a febrile form, often inapparent, or in a nervous form (dejection, tremors, neurological disorders). Spontaneous recovery generally occurs in 3 to 4 weeks, but serious forms with paralysis and death can occur.”.
Be careful, however, that human infection with West Nile virus can be asymptomatic, meaning the patient does not show any symptoms. “In some cases, the disease manifests itself as a flu-like syndrome (fever, headache, muscle pain) sometimes accompanied by a skin rash.”. In some cases, but this is rarer, it can cause serious neurological complications. If you experience these symptoms, it is urgent to go and consult.

The Prefect of Hérault calls for vigilance among equine owners, particularly those located in Petite-Camargue, as well as veterinarians in the equine sector. He recommends implementing preventive insecticide treatment and vaccination of horses and reminds that this disease must be declared by the veterinarian to the DDPP. Breeders are also called upon to apply preventive measures to protect themselves against mosquito bites in view of their possible exposure.
