When the world is experiencing a viral pandemic, scientists and health officials quickly want data-driven answers to understand the situation and better formulate a public health response. Technology provides tools that researchers can use to develop a rapid sequencing protocol. With such a protocol, the data generated can help answer questions about disease epidemiology and understand the interaction between host and virus. Even better: If the protocol is freely available and based on cheap, mobile sequencing systems.

What Caused the Black Death?

I was confident I knew a few things about the bubonic plague: It was caused by the bacterium Yersinia pestis, which was transmitted to humans by fleas hitching a ride on the back of traveling rats. It spread rapidly and devastated populations around the globe, and because cats, a natural predator of scurrying rodents, had been killed, rats proliferated along with their deadly, infectious cargo. However, until I read a recent PLoS ONE article, I did not realize there was still debate about whether Yersinia pestis was the infectious agent for Black Death, the disease that ravaged 14th century Europe and killed one third of its population.
