The chikungunya virus (CHIKV) is quickly spreading through the Western Hemisphere; as of May 15, 2015, the Pan-American Health Organization (PAHO) had tallied close to 1.4 million suspected cases and more than 33,000 confirmed cases since the virus’ first appearance in the Americas in December 2013. Spread by mosquitoes, chikungunya is rarely fatal but can cause debilitating joint and muscle pain, fever, nausea, fatigue and rash, and poses a growing public health and national security risk. Governments and health organizations could take more effective proactive steps to limit the spread of CHIKV if they had accurate forecasts of where and when it would appear. But such predictions for CHIKV and other emerging infectious diseases remain beyond the reach of current modeling capabilities.

Zika. Ebola. Dengue. Influenza. Chikungunya. These are but a few among the growing cadre of viruses that today pose serious health threats to U.S. troops, as well as to civilian populations in the United States and around the world. Vaccines exist for but a few of these infectious diseases. And since these viruses have an uncanny ability to mutate and morph as they reproduce inside their hosts, those few vaccines that do exist are quickly outdated, providing little protection against the latest viral strains. That’s why flu vaccine manufacturers, for example, must produce new versions annually, at enormous expense and with variable year-to-year efficacy.

Imagine the workplace during flu season. Some people get sick and display clear symptoms—a warning sign to coworkers to avoid contact and for that individual to stay home. Others are infected, but never or only belatedly exhibit the tell-tale signs of sickness, meaning they can infect coworkers without knowing it. If healthcare professionals had the ability to test in advance whether a person is likely to spread a disease following infection, they could recommend specific measures to treat the person or limit exposure and perhaps keep an outbreak from growing into an epidemic or pandemic.

A research team at the University of Washington has harnessed complex computational methods to design customized proteins that can self-assemble into 120-subunit “icosahedral” structures inside living cells—the biggest, self-booting, intracellular protein nanocages ever made. The breakthrough offers a potential solution to a pressing scientific challenge: how to safely and efficiently deliver to cells new and emerging biomedical treatments such as DNA vaccines and therapeutic interfering particles.

Over the past several years, DARPA-funded researchers have pioneered RNA vaccine technology, a medical countermeasure against infectious diseases that uses coded genetic constructs to stimulate production of viral proteins in the body, which in turn can trigger a protective antibody response. As a follow-on effort, DARPA funded research into genetic constructs that can directly stimulate production of antibodies in the body
