Among the functions of public health are health protection (e.g., food and water safety, basic sanitation), disease and injury prevention (including vaccinations and outbreak management), population health assessment; disease and risk factor surveillance; and health promotion.1
In the early 20th century, public health was well recognized as a major factor in ensuring the health of the community. Infectious diseases such as influenza, diphtheria, tuberculosis and polio cut wide swaths through the population, striking fear into the hearts of the afflicted and their families, as well as the physicians providing care. Millions died, including thousands of Canadians who succumbed to the “Spanish flu” (the influenza pandemic of 1918). Infants and children were particularly affected by diphtheria, gastroenteritis and polio. Bringing many of these killers under control through public health programs was hailed as one of the greatest accomplishments of medicine in the past century.2 As illness rates dropped, so did general interest in public health, only to rise again with the development of HIV/AIDS and SARS (severe acute respiratory syndrome), growing concerns about the impact of water and environmental contaminants, weather-related crises such as hurricanes, flooding and ice storms, and rising rates of obesity and other serious health problems. These more recent problems have all presented timely reminders of the importance of Virchow's 1848 principles of public health (Box 1),2 the central role of public health in the health of communities3 and the need for practitioners to be well versed in and connected to this area.
Given the important role of public health in maintaining the health and well-being of individuals and populations worldwide, CMAJ's public health team sees a need to expand the range and depth of public health coverage in the journal. The public health mission of CMAJ now has 3 major foci:
• to provide evidence-based public health information in a user-friendly fashion for practitioners and health care professionals
• to publish high-quality public health and social medicine research articles in a widely read and open-access venue
• to provide a forum for the discussion of contentious issues in public health
In fulfilling this mission, we will build on past successes, such as the timely reports and advice on Spanish flu by Boucher4 and McCullough5 in 1918, on tuberculosis chemotherapy by Florey6 in 1954 and on the SARS outbreak by Hoey7 and Maunder and associates8 in May 2003. We are expanding the range of articles (see Box 2) that will appear under the public health rubric in CMAJ. This issue, for example, includes 2 papers on HIV and hepatitis C infection among prison inmates9,10 and a related advocacy commentary on this important public health issue.11 When crises occur, we will help raise awareness of public health alerts, such as those issued by the Public Health Agency of Canada, using the online resources of e-CMAJ, as well as the print journal. When appropriate, we will also strive to mollify undue public alarm with reason, varied perspectives and timely, high-quality information.
Although some pieces for the public health section will be solicited, we also look forward to receiving unsolicited submissions from those working in the field, in academia and in government. All public health contributions will undergo peer review.
CMAJ is committed to improving health by disseminating knowledge that can be readily applied to practice and by advocating for changes in legislation and in program availability. As a major open-access medical journal, CMAJ can offer wide dissemination of timely research and commentary on issues relevant to the well-being of all. This expansion of the range of formats for public health articles, the breadth of topics to be covered and the size of the audience for this material signals CMAJ's commitment to the area and our recognition of its importance for the practitioners of today and for the health and well-being of Canadians for tomorrow.
