Best practices in ranking communicable disease threats: a literature review, 2015.

The threat of serious, cross-border communicable disease outbreaks in Europe poses a significant challenge to public health and emergency preparedness because the relative likelihood of these threats and the pathogens involved are constantly shifting in response to a range of changing disease drivers.

This paper reports on a literature review which identifies and evaluates the range of methods used for risk ranking.
