“…The opportunities for transmission of diseases of European derivation varied extensively, as did the effects they had on each community, and both of these were conditioned by the time, duration, and nature of the contact experience (Hurlich, 1983). Analyses of Aleut skeletons dating to the time of contact with Russian fur traders, for instance, show a significant increase in the prevalence of infection (Keenleyside, 2003). Introduced acute, directly transmitted diseases, such as smallpox, influenza, and measles, surely contributed to the increased disease burden as well, although direct evidence for them cannot be obtained through skeletal analyses.…”
