Grade 6 Poster Contest. Infectious Disease & Climate Change: Awareness & prevention in your community

The Canadian Public Health Association's poster contest is an opportunity for Grade 6 students from across Canada to learn more about climate sensitive infectious diseases like Lyme disease and West Nile virus, and share awareness and prevention information with their friends, family and communities. 

Submissions must be received by 9 February 2024..  

What are climate sensitive infectious diseases? Many diseases are sensitive to changes in the climate, including Lyme disease, West Nile virus, hantavirus, E. coli, giardiasis and salmonellosis. As the climate changes, so too do the patterns of who and where people get the disease. Learn more about climate sensitive infectious diseases.  

Who can enter? Grade 6 students, or students in a Grade 5/6 or 6/7 split class, registered in a Canadian school during the 2023-2024 school year.  

Prizes: Prizes will be awarded to a National Winner, a National Runner-up, and Regional Winners from Atlantic Canada, Quebec, Ontario, the Prairies, Alberta, and British Columbia & the Territories.  

     All winners will receive a copy of the book Grandpa’s Wisdom – An Algonquin Reflection on West Nile Virus and Lyme Disease
     by Albert Dumont. 

     Prizes must be accepted as rewarded.
     CPHA reserves the right to substitute a prize of equivalent value.
