An emerging infectious disease (EID) is an infectious disease that has appeared in a population for the first time, or that may have existed previously but is rapidly increasing in incidence or geographic range (WHO). Outbreaks are the occurrence of disease cases in excess of what would normally be expected for a community, geographical area or season (WHO). Examples of recent outbreaks in Canada include zoonotic diseases such as West Nile Virus (WNV), respiratory diseases like H1N1 Influenza virus, and food-borne diseases caused by Salmonella or E. coli.
The aim of this project stream at NCCID is to provide the most recent information available on emerging infectious diseases to public health practitioners, policy makers and public health inspectors, via webinars, podcasts, publications and other online resources. Through these products, we also aim to enhance and strengthen effective knowledge translation between health practitioners and the public amidst conflicting information from various sources.
Climate Change and Vector-borne Disease (VBD)
Vector-borne diseases (VBDs), caused by agents such as West Nile, Chikungunya virus, etc., pose a risk to the health of Canadians. Climate change has been predicted to have a significant impact on the distribution of vector-borne diseases and thus introduce new challenges to public health in Canada. Additionally, factors such as international travel and northward spread from other endemic southern areas of the continent contribute to the establishment of new outbreaks. These diseases can successfully be prevented through informed protective measures. NCCID seeks to respond to the growing need of public health practitioners with new information on climate change trends and emergence of VBDs that threaten the health of Canadians.

Public Health Quick Links: Zika Virus
Global attention to Zika virus continues with new information and developments nearly every week. NCCID has assembled these links to key leaders and sources in infectious diseases prevention, control and knowledge for public health in Canada.
- Public Health Agency of Canada (PHAC): Zika virus
- Center for Disease Control and Prevention (CDC): Zika & Pregnancy
- European Centre for Disease Control (ECDC): Factsheet for health professionals
- World Health Organization / Pan-American Health Organization (WHO / PAHO): Zika Communications Materials
Our first run of the Infectious Questions podcast focuses on an emerging infection very prominent in the media: Zika virus.
• IQ1: Zika Virus and pregnant travellers
• IQ2: Sexual transmission of Zika Virus
• IQ3: Birth defects and the Zika Virus
• IQ4: Should pregnant travellers to Zika-endemic areas undergo amniocentesis?
• IQ5: Should mothers infected with Zika during pregnancy breastfeed?
Disease Debriefs answer questions about important and emerging infectious diseases for public health decision makers, physicians, inspectors and nurses in community.
