Smallpox causes roughly 20% mortality whereas chickenpox causes less than 0.1%. Most 'verbal' (i.e. non-mathematical) discussions using a mortality definition of virulence would therefore label smallpox as more virulent. Indeed, the virulence of many diseases is measured using such case mortalities, chi, or related measures such as expected host lifespan, ...

The United States' international ranking for infant mortality slipped from 19th in the 1980s to 27th in 1997. This slippage may be related to the segregation of priorities that occurred early in the 1990s, when national concern was diverted from infant mortality to minority health. To rekindle concern about infant ...

A well-known result from the theory of the evolution of virulence is the prediction that the virulence of a pathogen (i.e. the rate of parasite-induced host mortality) always evolves to higher levels when host background mortality rates increase. This prediction, however, is derived from models that assume that host mortality ...
Singh P N - - 2001
The authors conducted a simulation study to evaluate whether exclusion of the early mortality (deaths occurring during a prespecified period immediately after baseline) reduces confounding of the exposure-mortality relation by preexisting disease. The simulation specified an exposure that decreased mortality risk in the absence of confounding and then introduced confounding ...

This article suggests that while disparities in infant mortality have been longstanding, the mechanisms of disparity creation are undergoing intense change. This dynamic character is explored by first developing an analytic model that examines the interaction between social factors and the public health and clinical capacity to intervene. Disparities in ...
