School Health Reference Guide


The Region of Peel School Health Reference Guide is a supplementary resource to relevant Peel and Dufferin-Peel school board policies. Refer to school board policy first if you have questions or concerns.

Childhood Diseases and Illnesses

West Nile Virus (WNV)
  • Spread to humans through the bite of an infected mosquito.  Mosquitoes become infected by biting an infected bird.
  • Symptoms usually appear within 3 to 15 days of being bitten by a mosquito.
  • Symptoms include fever, tiredness, body aches, occasional skin rashes and swollen lymph glands.
  • More serious illness may present with headache, high fever, neck stiffness, a lowered level of consciousness, confusion, coma, tremors, convulsions, muscle weakness and paralysis.
  • The illness can last as short as a few days to several weeks.
Instructions for Schools
  • Needs to be reported to Peel Public Health.
  • Call Peel Public Health at 905-799-7700 to report a case of West Nile Virus.
  • The mosquitoes that carry WNV are generally more active during the early morning and early evening, so children who attend school during the daytime are at minimal risk for exposure. 
  • Schools can reduce mosquitoes by removing breeding areas, including stagnant water, and taking precautions against mosquito bites.
  • Remember to protect the confidentiality of the student by not disclosing a diagnosis to concerned parents and/or colleagues. If contact follow up of those exposed is required Peel Public Health will contact those who are at risk.
  • There is currently no vaccine available to protect people against WNV.
  • Serious illness can occur in people of any age; however, people over age 50 and people with weakened immune systems are at the highest risk of getting severely ill when infected with WNV.
For more information on communicable disease resources and programs,
