The National Collaborating Centre for Infectious Diseases is one of six National Collaborating Centres for Public Health funded by the Public Health Agency of Canada. The six centres form a network across Canada, each hosted by a different institution and focusing on a different topic in public health. NCCID is hosted by the International Centre for Infectious Diseases (ICID), located in Winnipeg.

As part of our Partner Notification project, we are pleased to offer you our latest Evidence Review, “New Technologies for Partner Notifications for Sexually Transmitted Infections,” written by  Colin Lee, Public Health Physician, Communicable Disease Prevention and Control, Public Health Ontario  and Mayank Singal, Public Health and Preventive Medicine Resident, University of Alberta.  This paper reviews the literature and practices of public health organizations relating to the use of these new technologies for STI partner notification.
NCCID held an Influenza consultation, entitled “Reducing the Burden of Influenza Like Illness in Canada:  A National Consultation on Useful Products for Public Health Practitioners”, in Toronto, Ontario on March 28, 2013. This meeting served as a springboard for discussion on future work in the area of influenza and ILI that will be undertaken by NCCID and NCCPH. A summary of proceedings of the consultation is available on

A mathematical perspective of seasonal variations in Lyme disease transmission

Medical News Today, December 30, 2013
For Lyme disease to exist in an area, the bacteria that cause it, the ticks that carry the bacteria, and mammals that provide food to ticks in their various life stages must be present. Seasonal variations in temperature, rainfall and resource availability also affect disease transmission and dynamics.

"Ticks develop slowly or become less active in colder temperatures, and rainfall is also critically important for their development, survival, and activities," explains author Xiao-Qiang Zhao. "According to a report from the Public Health Agency of Canada on Lyme disease cases in Ontario between 1999 and 2004, most occurred in late spring and summer, when the young ticks are most active and people are outdoors more often."

A previous model proposed a reaction and diffusion model to study global dynamics of Lyme disease. A reaction-diffusion model takes into account the interaction (reaction) of constituents within the system (in this case pathogens, susceptible hosts and infective hosts) and their change in density over time within their respective populations (diffusion) Read More.
