The Division of Infectious Diseases plays a critical role in the prevention and management of infectious diseases through research, clinical care, and education. To help achieve these goals, the Division has close ties to the Department of Pathology and Molecular Medicine at McMaster, the Michael G. DeGroote Institute for Infectious Disease Research, the Hamilton Regional Laboratory Medicine Program, and the Department of Clinical Epidemiology and Biostatistics. Collaborations at the provincial, national, and international level bolster research and education activities through funding from agencies such as CIHR and NIH. Faculty members are committed to providing quality patient care that brings the best evidence based findings to bedside practice.

As a core mission of the Division, the fellowship program provides a superior experience for trainees. A regionalized healthcare system at the major teaching hospitals in Hamilton offers fellows a wide breadth of clinical experience. Royal College reviewers cited the diversity of cases as a key strength of the training program. The Division makes a major contribution to the MD Program as well as to postgraduate programs, including both clinical and basic science. Faculty members play major roles in training in the Health Research Methodology program. Trainees benefit from Faculty recognized nationally and internationally for their expertise in infectious diseases.

Current research activities include vaccine and epidemiologic studies on influenza, genetic epidemiologic studies on influenza, dengue, and West Nile virus, molecular epidemiologic investigations on respiratory viruses, immunologic response to vaccination, determinants of susceptibility to infection in the elderly, tuberculosis vaccine evaluation, clinical and molecular mycology, and clinical studies on community acquired pneumonia.

The division continues to develop strength in connecting fundamental research and epidemiological studies, bringing benefits across Canada as well as internationally. Our goal is to increase the breadth and depth of our research, increase the integration of trainees in these areas, which ultimately will lead to further significant advances in the field of infectious diseases.
