Yellow Jack, or as we know it better today Yellow Fever, has rightly been called the plague of the Americas. It has long been assumed that yellow fever came to the Americas with its vector,...

The Landscape of Super-Spreading

Super-spreading individuals and disease hot spots have been known for over a century, but rarely have they been considered together. Sara Paull and colleagues [1] have pulled together all of the recent work the ecology of disease hot spots and transmission heterogeneity (super spreading) to explore the continuum between individual transmission heterogeneity and the landscape...

Despite the difficulties of using fenlands, these areas were not only occupied throughout the Anglo-Saxon... Continue Reading →

Did India and China Escape the Black Death?

Genetic diversity and biogeography suggest that Yersinia pestis evolved in East Central Asia (S. Russia, Mongolia, N. China) and spread along the Eurasian steppe from the Caspian Sea in Kazakstan to the Mongolia... Continue Reading →

Cradle of Cholera’s Seventh Pandemic Found

Vibrio cholerae emerged on a global stage in the 19th century just in time for the beginnings of modern medicine to grapple with it and for its transmission to prove the worth of epidemiological work. Although we understand its treatment and transmission... Continue Reading →

When Anthrax first came to North America

When pathogens arrived in the Americas is important for understanding the demographic history and biogeography of humans, animals and microbes of the Western Hemisphere. There have been two major periods of human migration to this hemisphere: across the Bering Land Bridge from Asia during the last Ice Age and the arrival of Christopher Columbus in...
