More than 288,000 Americans have been killed by a virus that public health officials now say can be spread through airborne transmission. The virus spreads most commonly through close contact, scientists say. But under certain conditions, people farther than six feet apart can become infected by exposure to tiny droplets and particles exhaled by an infected person, the Centers for Disease Control and Prevention said in October. Those droplets and particles can linger in the air for minutes to hours. To visually illustrate the risk of airborne transmission in real time, The Washington Post used a military-grade infrared camera capable of detecting exhaled breath. Numerous experts — epidemiologists, virologists and engineers — supported the notion of using exhalation as a conservative proxy to show potential transmission risk in various settings. The highly sensitive camera system detects variations in infrared radiation that are not visible to the naked eye. The technology is more typically used in military and industrial settings, such as detecting methane gas leaks in pipelines. In 2013, it was deployed by law enforcement during the 20-hour manhunt for the Boston Marathon bombers. But fitted with a filter that specifically targets the infrared signature of carbon dioxide, the camera can be used to map in real time the partial path of the nearly invisible particles we exhale.
