Niagara Region Public Health has confirmed its first case of West Nile virus in a person this year.

West Nile virus is caused by the bite of a mosquito infected with the virus.

The health agency says most people infected with West Nile virus have no symptoms, however, about 20 per cent of people experience flu-like symptoms and fatigue.

It says only one per cent of infected people experience severe symptoms, such as a quick severe headache, neck stiffness, confusion, weakness and sudden sensitivity to light.

“Older individuals or individuals with compromised immune systems are at higher risk of developing severe symptoms,” Niagara Region Public Health said in a press release Friday.

Those concerned about their symptoms are urged to visit their health-care provider.

The health agency is also reminding residents to protect themselves against bites by using a mosquito repellent and wearing long-sleeved shirts and pants at dawn or in the evening.

It says standing water should be drained to prevent breeding, and damaged doors and window screens should be repaired.
