An account of the experiment conducted by U.S. Public Health Service describes how medical treatment was withheld from Black sharecroppers infected with syphilis
The most frequent infectious diseases in humans--and those with the highest potential for rapid pandemic spread--are usually transmitted via droplets during close proximity interactions (CPIs). Despite importance of this transmission route, very little is known about dynamic patterns CPIs. Using wireless sensor network technology, we obtained high-resolution data CPIs a typical day at an American high school, permitting reconstruction social relevant disease transmission. At 94% coverage,...
Cooking is a human universal that must have had widespread effects on the nutrition, ecology, and social relationships of species invented it. The location timing its origins are unknown, but it should left strong signals in fossil record. We suggest such detectable at ca. 1.9 million years ago reduced digestive effort (e.g., smaller teeth) increased supply food energy larger female body mass) early Homo erectus. adoption cooking required delay consumption while was accumulated and/or...
The dynamics of infectious diseases spread via direct person-to-person transmission (such as influenza, smallpox, HIV/AIDS, etc.) depends on the underlying host contact network. Human networks exhibit strong community structure. Understanding how such structure affects epidemics may provide insights for preventing disease between communities by changing network through pharmaceutical or non-pharmaceutical interventions. We use empirical and simulated to investigate in with find that has a...
Aboriginal burning in Australia has long been assumed to be a “resource management” strategy, but no quantitative tests of this hypothesis have ever conducted. We combine ethnographic observations contemporary hunting and with satellite image analysis anthropogenic natural landscape structure demonstrate the processes through which shapes arid-zone vegetational diversity. Anthropogenic landscapes contain greater diversity successional stages than under lightning fire regime, differences are...
Background Since late April, 2009, a novel influenza virus A (H1N1), generally referred to as the “swine flu,” has spread around globe and infected hundreds of thousands people. During first few days after initial outbreak in Mexico, extensive media coverage together with high degree uncertainty about transmissibility mortality rate associated caused widespread concern population. The an infectious disease can be strongly influenced by behavioral changes (e.g., social distancing) during...
"We propose to change the default P-value threshold forstatistical significance for claims of new discoveries from 0.05 0.005."
To prospectively quantify the number of unrecognized missed out-of-hospital intubations by ground paramedics using emergency physician verification as criterion standard for endotracheal tube placement.The authors performed an observational, prospective study consecutive intubated patients arriving medical services to two urban teaching hospitals. Endotracheal placement was verified physicians and evaluated a combination direct visualization, esophageal detector device (EDD), colorimetric...
Introduction The HIV pandemic disproportionately impacts young women. Worldwide, women aged 15–24 are infected with at rates twice that of men, and alone account for nearly a quarter all new infections. incommensurate incidence in – often poor underscores how social economic inequalities shape the epidemic. Confluent forces, including political gender violence, poverty, racism, sexism impede equal access to therapies effective care, but most constrain agency Methods prevalence data was...
Reducing the burden of neglected tropical diseases (NTDs) is one key strategic targets advanced by Sustainable Development Goals. Despite unprecedented effort deployed for NTD elimination in past decade, their control, mainly through drug administration, remains particularly challenging: persistent poverty and repeated exposure to pathogens embedded environment limit efficacy strategies focused exclusively on human treatment or medical care. Here, we present a simple modelling framework...
Understanding how gendered economic roles structure space use is critical to evolutionary models of foraging behaviour, social organization and cognition. Here, we examine hunter-gatherer spatial behaviour on a very large scale, using GPS devices worn by Hadza foragers record 2,078 person-days movement. Theory in movement ecology suggests that the density mobility targeted foods should predict strong gender differences arise context. As predicted, find men walked further per day, explored...
