Common airline boarding practice makes spread of disease more likely, study says

The common practice of boarding airline passengers by classes is the worst way to avoid spreading infectious diseases, according to a study from Arizona State University. The study found that infection rates increased when passengers were crowded together — as they often are while trying to board a plane. In the case of an Ebola outbreak, the study said that the current boarding practice used by most airlines would lead to a 67% chance of 20 air-travel-related cases a month. Furthermore, the study found that bigger planes with more passengers can also lead to higher infection rates. The study recommends a few fixes to reduce the infection rate, such as dividing the plane into 2 lengthwise sections and loading passengers randomly to cut down on bottlenecks. <br/>
