Worms & Germs Map


About WormsAndGermsMap

WormsAndGermsMap is an interactive, real-time disease mapping system designed to track selected infectious diseases of companion animals (including horses). It is a companion to the educational site WormsAndGermsBlog. Both were developed by Dr. Scott Weese of the University of Guelph and Dr. Maureen Anderson from the Ontario Ministry of Agriculture and Food.

This disease mapping site was developed because we perceived a need for real time tracking of companion animal infectious diseases and a need to foster more knowledge about infectious diseases amongst vets, animal owners and people in human medicine and public health.  It may also help track emerging diseases, diseases that have a changing range and allow for more rapid identification of outbreaks.
