Similarly, historian Jeffrey Ostler at The University of Oregon has argued that population collapses in the Americas throughout colonization were not mainly due to lack of Native immunity to European disease. Instead, he claims that "When severe epidemics did hit, it was often less because Native bodies lacked immunity than because European colonialism disrupted Native communities and damaged their resources, making them more vulnerable to pathogens." In specific regards to Spanish colonization of northern Florida and southeastern Georgia, Native peoples there "were subject to forced labor and, because of poor living conditions and malnutrition, succumbed to wave after wave of unidentifiable diseases." Further, in relation to British colonization in the Northeast, Algonquian speaking tribes in Virginia and Maryland "suffered from a variety of diseases, including malaria, typhus, and possibly smallpox." These diseases were not solely a case of Native susceptibility, however, because "as colonists took their resources, Native communities were subject to malnutrition, starvation, and social stress, all making people more vulnerable to pathogens. Repeated epidemics created additional trauma and population loss, which in turn disrupted the provision of healthcare." Such conditions would continue, alongside rampant disease in Native communities, throughout colonization, the formation of the United States, and multiple forced removals, as Ostler explains that many scholars "have yet to come to grips with how U.S. expansion created conditions that made Native communities acutely vulnerable to pathogens and how severely disease impacted them. ... Historians continue to ignore the catastrophic impact of disease and its relationship to U.S. policy and action even when it is right before their eyes."
