Vector-borne Illnesses: Avoid the Bite!

Vector-borne illnesses are those passed to people through another source, such as a mosquito or a tick. These illnesses are not currently widespread in the Northeastern Ontario area. There is a possibility that, as a result of changes in climate and migration, the mosquitoes and ticks that are capable of causing illnesses could one day be a concern.

West Nile Virus (WNV) is transmitted from the bite of an infected mosquito. During the summer months, the Porcupine Health Unit conducts weekly mosquito trapping and testing to determine if WNV is present in our area. 

Lyme disease is an infection transmitted through the bite of an infected tick. In Ontario, Lyme disease is only transmitted through the black-legged tick. The majority of human cases reported occur as a result of exposure to areas known to harbour infected black-legged ticks. At this time, there are no reported cases of Lyme disease in the Porcupine Health Unit area however the black-legged tick has been identified.
