Mosquitoes carrying West Nile Virus have shown up once again in the Belleville area.
Hastings Prince Edward Public Health found evidence of the virus as part of its regular surveillance.
Traps were set at 17 locations, including Bancroft, Belleville, Bloomfield, Stirling and Quinte West. The first positive mosquitoes were found in Belleville in late July.
To date there has been a total of 13 positive pools of mosquitoes identified, which include traps that presented positive multiple times.
Public health officials say West Nile Virus is an infection found in birds, and carried by mosquitoes which feed on infected birds. It is spread to humans and animals through bites by infected mosquitoes.
Early symptoms can include fever, muscle weakness, stiff neck, confusion, severe headache, sudden sensitivity to light, tremors, numbness, or vision loss.
The majority of people infected have mild symptoms but a severe case can cause inflammation of the brain known as encephalitis.
