Resumo

Beginning some 10,000 years ago, humans began a dramatic alteration in living conditions relating especially to the shift in lifeway from foraging to farming. In addition to the initiation of and increasing focus on the production and consumption of domesticated plant carbohydrates, this revolutionary transformation in diet occasioned a decline in mobility and an increased size and agglomeration of populations in semipermanent or permanent settlements. These changes in life conditions presented an opportunity for increased transmission of pathogenic microbes from host to host, such as those that cause major health threats affecting most of the 7.5 billion members of our species today. This article discusses the bioarchaeology of infectious disease, focusing on tuberculosis, treponematosis, dental caries, and periodontitis, all of which continue to contribute to high levels of morbidity and mortality among the world's populations today.
