"This is quite a large epidemic, so another question is how did this get so big so fast? And no one has the answer," said Hotez. "There's nothing really published, most of what we’re going on are World Health Organization alerts."

Ebola is nightmare fuel: a biological doomsday device conspiring with our bodies to murder us in uniquely gruesome fashion. It’s also killed fewer than 2,000 people. How has a virus with such a modest body count so fiercely captured the darkest corners of our imagination? - Leigh Cowart for Haziltt.
The Norovirus: A Study in Puked Perfection, "Each norovirus carries just nine protein-coding genes (you have about 20,000). Even with that skimpy genetic toolkit, noroviruses can break the locks on our cells, slip in, and hack our own DNA to make new noroviruses. The details of this invasion are sketchy, alas, because scientists haven’t figured out a good way to rear noroviruses in human cells in their labs. It’s not even clear exactly which type of cell they invade once they reach the gut. Regardless of the type, they clearly know how to exploit their hosts. Noroviruses come roaring out of the infected cells in vast numbers. And then they come roaring out of the body. Within a day of infection, noroviruses have rewired our digestive system so that stuff comes flying out from both ends." [more inside]
A German researcher accidentally jabbed her finger with a hypodermic loaded with the deadly Ebola virus. 48 hours later, she was injected with an untested, experimental vaccine, developed by an international team of virologists and biologists. Though she may never have been infected, she was certainly in danger; in 2004, a similar incident caused the death of a Russian scientist at a former Soviet biological weapons lab.
