OBJECTIVES Over time, quarantine has become a classic public health intervention and has been used repeatedly when newly emerging infectious diseases have threatened to spread throughout a population. Here, we weigh the economic costs and benefits associated with implementing widespread quarantine in Toronto during the SARS outbreaks of 2003. METHODS We compared the costs of two outbreak scen...

Globalization has led to an increase in the spread of emerging and re-emerging infectious diseases. International efforts are being launched to control their dissemination through global surveillance, a major hindrance to which is the failure of some countries to report outbreaks. Current guidelines and regulations on emerging and re-emerging infectious diseases do not sufficiently take into ac...

Lévy flights are scale-free (fractal) search patterns found in a wide range of animals. They can be an advantageous strategy promoting high encounter rates with rare cues that may indicate prey items, mating partners or navigational landmarks. The robustness of this behavioural strategy to ubiquitous threats to animal performance, such as pathogens, remains poorly understood. Using honeybees ra...

Newly emerging infectious diseases (nEIDs) have increased rapidly presenting alarming challenges to global health. We argue that for effective management of global health a basic strategy should include at least three essential tactical forms: actions of a directly focused nature, institutional coordination, and disciplinary integration in approaches to health management. Each level of action i...

The paper by Barry Eichengreen and Ricardo Haussman is correct to focus on the policies that the emerging market countries (EMC) themselves can pursue to reduce the risk of future economic crises, instead of discussing new policies for the IMF or for the industrial countries that some analysts hope might achieve that goal. I agree with their emphasis on EMC self-help and on the multiple causes ...

Before the severe acute respiratory syndrome (SARS) outbreak, the Centers for Disease Control and Prevention's (CDC) legal authority to apprehend, detain, or conditionally release persons was limited to seven listed diseases, not including SARS, and could only be changed using a two-step process: 1) executive order of the President of the United States on recommendation by the Secretary, U.S. D...

Human population growth, technological advances, and changing social behaviors lead to the selection of new microbial pathogens. Antimicrobial drugs, vaccines, diagnostics, and treatments for emerging infectious diseases must be developed. The selective forces that drive the emergence of new infectious diseases, and the implications for our survival, are just beginning to be understood.

Early detection of disease outbreaks in human and animal populations is crucial to the effective surveillance of emerging infectious diseases. However, there are marked geographical disparities in capacity for early detection of outbreaks, which limit the effectiveness of global surveillance strategies. Linking surveillance approaches for emerging and neglected endemic zoonoses, with a renewed ...

Mathematical models of transmission have become invaluable management tools in planning for the control of emerging infectious diseases. A key variable in such models is the reproductive number R. For new emerging infectious diseases, the value of the reproductive number can only be inferred indirectly from the observed exponential epidemic growth rate r. Such inference is ambiguous as several ...
