West Nile virus found in mosquitoes in Brampton, Peel’s first case this year

West Nile virus is most commonly spread to humans through bites from infected mosquitoes, according to Health Canada. The disease cannot be transferred by touching or kissing someone who has already caught it. 

Common symptoms of West Nile

The virus’ first symptoms usually appear within two to 15 days after infection and can include fever, headache, body aches, mild rashes or swollen lymph glands. 

Those with underlying conditions, weaker immune systems or who are 50 years or older are at greater risk of developing more serious symptoms like nausea, loss of consciousness or paralysis.

Anyone who begins developing symptoms of West Nile virus after being bitten by a mosquito should seek health care immediately.

How to prevent West Nile infection

Health Canada says the best way to avoid becoming infected with West Nile virus is to prevent mosquito bites altogether.

Individuals who are planning to spend time outdoors can wear long pants, loose-fitting shirts with long sleeves, socks and a hat to cover as much exposed skin as possible. They can also try wearing light-coloured clothing or a mosquito net over their hat.

If possible, people should also use insect repellents to reduce the risk of mosquito bites. 

Mosquitoes also lay eggs in standing water, so homeowners can remove their habitats by draining old tires, rainwater barrels, wading pools or anywhere else water might collect. They should also clean eavestroughs regularly to prevent clogs that could trap water and replace the water in outdoor pet dishes and bird baths at least twice a week.

Canadians can track confirmed West Nile virus cases in their area on the Health Canada website or through their local public health department.
