The West African Ebola outbreak is finally starting to approach manageable levels, after nearly 18 excruciating months and over 11,000 lost lives. Here’s what the current situation on the ground looks like and how the battle against Ebola finally might be won.
The Black Death wiped out nearly half the population of Europe during the 14th Century, a blight that swept through the continent in the gut of fleas. But a new analysis of ancient human DNA shows that the dreaded bacteria emerged at least 3,000 years before the first plague pandemic—a time before it mutated into its…
Around 60% of all human diseases and some 75% of all emerging infectious diseases are zoonotic, meaning they spread from species to species. This remarkable visualization shows how these problematic pathogens proliferate among the animals.
Having stamped out a number of tropical diseases—including malaria—decades ago, is the United States today complacent about a rising wave of infectious disease?
To fans of Game of Thrones, Greyscale and its disruptive terror might be a reminder of the Black Death or those mysterious poxes and fluxes that chroniclers wrote about in the era before modern medicine. But Greyscale’s allure for contemporary audiences can actually be traced back to a biblical mistranslation of…
Last October, Dr. Ian Crozier was released from Emory University Hospital after nearly losing his life to Ebola. Months later, he began to experience pain and fading vision in his left eye. Within a few days, his iris, which is normally blue, had turned green.
On April 17, California health officials declared the large measles outbreak that began last December at Disneyland over. But the outbreak remains active in Canada, where its persistence highlights the looming risk of measles’ return in the United States.
Colonel Dan Wattendorf is a program manager in DARPA's Defense Sciences Office. His goal: To dramatically suppress Ebola, and infectious diseases like it, with a new, unconventional vaccine. And according to Wattendorf, the biggest hurdles he faces in accomplishing this mission "aren't scientific, but institutional."
A new research letter published in JAMA Pediatrics is the first to positively link low vaccination rates to the Disneyland measles outbreak that emerged in California late last year. The new research also shows how frighteningly fast measles can spread in a population that's insufficiently immunized against the highly…
West Africa's Ebola outbreak could be stanched by mid-year – but in the epidemic's wake, another public health crisis looms. Disruption of the region's already feeble health care systems has derailed health campaigns targeting childhood diseases, leaving the door wide open for measles and other preventable illnesses.
An unconventional take on vaccine design has been shown to protect mice against HSV-1 and HSV-2, the two most common forms of herpes that cause cold sores and genital ulcers, respectively.
A new, noninvasive technique has been used to create a real-time map of the simian AIDS virus (SIV) in the entire body of a living monkey, researchers report today. The method is called immunoPET, and it's already turning up unexpected "viral reservoirs" where AIDS may gain a purchase in the body.
Researchers know that HIV jumped from apes and monkeys to humans on multiple occasions, in the form of HIV-like viruses called simian immunodeficiency viruses (SIV). To date, 11 out of 13 of these cross-species transmissions have been accounted for. On Monday, researchers identified the final two.
By using the same syringe to give injections to multiple people, health practitioners around the world are significantly driving the spread of many deadly infectious diseases. In an effort to deal with this problem, the WHO is pushing for syringes that cannot be used more than once — and they want this worldwide…
For parents living in North America and other developed countries, the choice not to have children immunized is a luxury and a privilege. As this map makes painfully clear, there are many parts of the world where it's the inaccessibility of vaccines that's the problem.
As parts of North America struggle to contain a completely unnecessary measles epidemic, it's important to remember what life was like prior to the onset of vaccines. These maps paint a grim picture of the past — and where we ourselves may be headed in the future.
Though over 1 billion people suffer from them, they're called "neglected diseases." That's because they attract little public attention and research money. But these diseases are about to explode across the globe, which is why many doctors say the neglect needs to stop now.
U.S. scientists studying throat microbes have inadvertently stumbled upon an algae virus that appears to have a slight but measurable detrimental affect on cognitive functioning in humans, including visual processing and spatial orientation. Disturbingly, millions of us could already be infected.
We've been hearing a lot about how Ebola is both not very contagious and, at the same time, highly infectious. Could both be true? It turns out, yes.
A terrifying feature of the deadly rabies virus is how fast it moves along the body's nervous system toward the brain, at speeds approaching half a meter per day. Its speed has been a medical mystery – but now researchers have a promising new lead that could explain how rabies spreads.
