The National Advisory Committee on Immunization recommends “influenza vaccination for all individuals aged six months and older” in Canada. But what is the evidence for universal programs? In this webinar, Dr. Richard Schabas (Chief Medical Officer of Health for Ontario from 1987-97, now the Medical Officer of Health for the Hastings & Prince Edward Counties Health Unit) explored this question, including the impact and implications of new research.Read More
Standard burden of disease measures identify differences in disease patterns and trends for a population, but do not always look for differences within the population. We need a different approach to thinking about and measuring burden of disease—one that considers the social determinants of health and the effects of inequity.Read More
Closing schools seems like a logical approach to managing community outbreaks of influenza. First, school-aged children are among the age groups more susceptible to influenza infection. Second, they tend to shed more of the virus into their environments, increasing the risk of exposure for those around them. Third, they live, learn, and play in close contact with many others – classmates, friends, teachers, family members, and caregivers. As a result, limiting contact among school-aged children should, in theory, reduce the spread and lessen the impact of pandemic or seasonal influenza, both among children and in the broader community. In practice, however, the effectiveness of school closures for managing outbreaks or severe outcomes related to influenza is unclear. Research on school closures has sometimes lacked rigour, often led to contradictory findings, or been insufficient to answer some of the more important questions.Read More
This concept paper serves as a starting point for a critical examination of burden of disease, with the longer-term goal of developing a framework to guide transparent, fair, meaningful, and practical measures of burden.Read More
Understanding Summary Measures Used to Estimate the Burden of Diseases: All About HALYs, DALYs and QALYs
Summary measures of the burden of disease in a population are popular and widely used, as they can simplify complex information about diseases, including risk factors, and the likelihood of resulting disability or other harm (morbidity), or death (mortality). This factsheet introduces the basic summary measures of burden of disease.Read More
The document provides an overview of recent literature and evidence for the potential health benefits, costs, as well as ethical considerations of school closure during influenza outbreaks.Read More
This document provides a review of terms commonly used in modelling studies of influenza infection spread and control. The objective is to understand the similarities and discrepancies between definitions of the same terms used in different studies. Standardization of terms should reduce variation in study results produced by different research communities, and should improve the accessibility and policy-relevance of new knowledge for public health decision-makers.Read More
This document provides details of the proposed logical framework for influenza infection, including several modules for public health interventions and their effects in prevention and control of illness. These interventions include vaccination, use of antiviral drugs, and hospitalization. The aim of this logical framework is to enhance the utility and uptake of modelling for public health responses by building a conceptual framework for common assumptions, plausible interventions, disease outcomes, and the impact of control measures at various stages of infection.Read More
