Disease detection, prevention, and response in developing areas
In a village in southeastern Guinea, a 2-year old boy spiked a fever and became gravely ill. He died in a matter of days. Soon his family became sick, then mourners at their funerals, then a health worker and relatives of the sick. It would be 3 months before health officials knew the identity of the deadly disease: Ebola.1 Since the dawn of the 2014 epidemic, the virus has reached 6 countries, crippled fragile economies, and claimed more than 11,000 lives.2
Global health security relies on the ability to quickly recognize and respond to disease outbreaks. The 2014 Ebola crisis underscores how epidemics not only exact a toll public health, but on national economies as well. Fearful of contagion, workers stay home, businesses close, and transportation is disrupted. The impact can ripple around the world.
WSU researchers seek ways to stop outbreaks before they start. They are developing objective, data-driven methods for disease detection and response for use in resource-poor environments. Working across disciplines, scholars identify barriers to halting the spread of disease, be they political, economic, social, behavioral, or cultural. They aim to create disease surveillance and response systems that will be sustainable at all levels of governance. New models under development will serve the global community.

Reducing the threat of rabies in Africa
Experts seek ways to confer protection in nations with scant medical resources
Canine rabies has been eliminated in developed countries but remains a threat to half the world, including the African nation of Tanzania. The bite from a rabid dog is often deadly to humans living in Africa and Asia, where there is poor access to expensive post-exposure vaccinations. According to estimates by the World Health Organization, rabies takes the lives of nearly 60,000 people each year, including approximately 1,500 in Tanzania. Almost half of those are children under the age of 15.
The obvious solution is to vaccinate dogs against the disease, but it … » More …Read Story
Disarming a deadly virus
Scientist discovers how infection with the deadly Nipah virus takes hold
Everyone has seen it in the movies: a deadly virus breaks out of a remote locale and spreads like wildfire, causing devastation with worldwide consequences. Although frequently over-dramatized by Hollywood, it’s a real possibility— as evidenced by the recent Ebola outbreak, which saw cases appear in Europe and the Americas for the first time.
In the School for Global Animal Health at WSU Pullman, virologist Hector Aguilar-Carreno is hard at work making sure the deadly Nipah virus can’t do the same thing.
His work is urgent. With a mortality rate of 40% to … » More …Read Story
