Insights into the evolution of virulence may aid efforts to control or even prevent emerging diseases. Specifically, dangerous pathogens can be distinguished from those that pose relatively little threat by identifying characteristics that favor intense exploitation of hosts by pathogens, hence causing high virulence. ⋯ These insights may improve the return on investments in disease control by directing effort and resources to the most-dangerous emerging pathogens. The approach also should help us to identify those control measures that will guard against the future emergence of dangerous pathogens, even those that have not yet been identified.

Developmental screening scores among preschool-aged children: the roles of poverty and child health.
To investigate, using a nationally representative sample of preschool-aged children, the relationship among poverty history, child health, and risk of an abnormal developmental screening score. ⋯ Poverty is the largest single predictor of an abnormal developmental screening score. The implications of inadequate medical care among poor children for the interpretation of individual screening scores and for amelioration of problems are also discussed.
