West Nile virus infection: cases in Montérégie
By: Alexandre Brouillard
The first cases of West Nile virus infection were recently reported in Montérégie. This disease is transmitted to humans by an infected mosquito.
The Montérégie Public Health Department (DSP) reminds the population of the importance of protecting themselves against mosquito bites throughout the summer, and until the first frosts of fall.
In the majority of cases (80%), people infected with West Nile virus recover spontaneously, without being bothered. However, some mild symptoms may appear two to 14 days after being infected, including headache, fever, stomach aches, nausea, muscle aches or redness of the skin.
Less than 1% of people infected with the virus will develop a serious form of the disease such as meningitis, encephalitis or paralysis of the lower limbs. People aged 50 and over, those with chronic diseases and those with weakened immune systems are at greater risk of developing complications.
There is currently no specific treatment or vaccine for West Nile virus. The best way to prevent infection is to avoid mosquito bites. Simple steps can be taken to protect yourself: wear light-coloured, long clothing when outdoors, use mosquito repellent, install properly functioning screens on doors and windows of your home, and cover strollers and playpens with mosquito netting when they are outdoors.
