John O. Lee, M.D., C.C.F.P., F.C.F.P., Certificate in Travel Health, member CATMAT

I am a Family Physician who has been practicing Travel Medicine since 1996. I graduated from the University of Alberta Medical School in 1990 and finished my Family Medicine Training at McGill University in 1992. I worked years of Emergency Medicine and Surgical Assist. I decided to spend 1994-1997 working overseas in Africa. I served as a volunteer doctor with Médecins Sans Frontières (Doctors Without Borders) in Zaire, Rwanda, and Burundi shortly after the Rwanda Massacre. I have also worked with World University Service of Canada, United Nations High Commissioner for Refugees, World Health Organization, and the John Hopkins University School of Epidemiology. I have personally treated malaria, dengue fever, yellow fever, typhoid fever, cholera, dysentery, schistosomiasis, onchocerciasis, hepatitis A & B, AIDS, tuberculosis, tetanus, measles, meningitis, and polio. I am a member of the Committee to Advise on Tropical Medicine and Travel (CATMAT) - a national committee of epidemiologists, infection disease specialists and public health leaders who set national policy on travel medicine.

My practical approach is based not only on the current evidence but the experience of having lived, worked, and treated those who have been ill abroad. I continue to maintain a busy family practice but will always make room for Travel Medicine patients. I also maintain privileges at the Queensway-Carleton Hospital doing surgical assist, newborn examinations, and acting as Education Director for the Department of Family Practice. I received my certificate in Family Medicine in 1992 and my Fellowship in the College of Family Physicians of Canada in 2011. I earned a Certificate in Travel Health through the International Society of Travel Medicine in 2003. I have served as a member of CATMAT since 2019.
