The U.S. Army's Edgewood Chemical Biological Center has developed the Integrated Virus Detection System (IVDS). Operating electronically, the IVDS takes an air sample and sorts and counts all viruses present. Using other markers, the IVDS can determine is unknown viruses are present. The technology has been licensed to a civilian firm (Virus Detection Systems) for production. Ultimately, the army wants to develop a cheaper and autonomous IVDS that can be placed in many areas to automatically scan for unknown viruses. Actually, there are a lot of unknown viruses out there, but they often show up in predictable cycles. A new, but artificial, virus would stand out. Or at least that's the theory.
