West Nile Virus

Cases of West Nile Virus infections have been reported in Quebec, including some in Laval.

Contrary to popular belief, mosquito-transmitting West Nile Virus is more prevalent in urban areas. It is therefore necessary to take all necessary measures to guard against this infection, especially those aged fifty or more and people with a weakened immune system or suffering from a chronic disease, who are at higher risk of developing complications.

It is also very important to use mosquito repellent, according to the manufacturer's instructions, and apply it to exposed body parts, avoiding the face. 

In addition, it is possible to help reduce the risk of acquiring infection by installing mosquito nets on windows and doors of houses or outdoor shelters, and by removing stagnant water points or puddles near waterways. inhabited places, because these environments are used for the reproduction of mosquitoes.
