City of Hamilton reports first local human case of West Nile virus this season

The City of Hamilton Public Health Services reported Monday the first local human case of West Nile virus this season.

City staff said this has prompted the Hamilton’s Medical Officer of Health to increase the virus’ risk to “high.”

They say residents should stay vigilant to prevent mosquito breeding by removing standing water.

“It is important to take precautions to avoid illnesses spread by insects including West Nile Virus, Lyme disease, and Eastern equine encephalitis,” said Dr. Bart Harvey, the Associate Medical Officer of Health for Hamilton.

Residents are also reminded to protect themselves against mosquito bites by covering up in light coloured clothes with long sleeves, long pants, and by using bug spray that contains DEET or Icaridin.

City staff say around 80 per cent of people infected with West Nile virus will not show symptoms, but those with weakened immune systems may develop severe illnesses.

Symptoms often appear two to 15 days after being bitten by an infected mosquito.

Mild symptoms can include: fever, headache, nausea, vomiting, a rash on the chest, stomach or back, and body aches.

More severe symptoms can include a stiff neck, tremors, high fevers, numbness and a sensitivity to light.

While there is no specific treatment or vaccine for West Nile virus, anyone that believes they are showing symptoms should contact their doctor.

The first human case of the virus acquired in Canada was confirmed earlier this month in Toronto.
