It was first brought to light in the early 1970s, when researchers realized one of the most common common cold viruses, rhinovirus, seemed to put asthmatics as a higher risk for complications. Unfortunately, the technology was not in place to figure out exactly how the viruses were causing the trouble. All that could be done was to offer a warning for other doctors to look out for this combination.

As the ability to examine our bodies at the molecular level increased, so did our understanding of how asthma patients responded to the virus. By the end of the 1990s, a clearer picture of the process was in place. There appeared to be a…
