Nach dem Ebola-Ausbruch in Westafrika 2014 haben Forscher der Florida State University untersucht, was das Ansteckungsrisiko bei Flugreisen beeinflusst. Dabei kommt man zu dem Schluß dass das weitverbreitete Gruppen-/Zonen-Boarding das Risiko einer Infektion erhöht:
Als Alternative wird eine Unterteilung des Boardings in linke und rechte Seite des Flugzeuges empfohlen:
Theorie schön und gut, aber in der Praxis sehe ich dennoch nicht wie ein rechts/links-Boarding die Menschentrauben (die ja als Begründung für das höhere Infektionsrisiko beim Gruppen-Boarding genannt werden) verhindert.
"It turns out that procedures that are generally good at getting people onto a plane very fast are also very bad at preventing infection." The team used sophisticated supercomputer simulations to identify air-travel procedures most prone to the spread of infection. Their findings are enough to unnerve frequent fliers: Not only is boarding more dangerous than deplaning in terms of disease transmission, but the three-zone boarding system so commonly used among popular airlines is appreciably worse than the alternatives. It's the clustered, huddled crowds that make the multiple-zone systems, where parceled groups of passengers board in congregated groups, so ripe for contagion.
Als Alternative wird eine Unterteilung des Boardings in linke und rechte Seite des Flugzeuges empfohlen:
According to the researchers, a better option might be a two-zone system where the plane is divided lengthwise in dual columnar sections, with passengers in each section boarding at random. While this system might sacrifice efficiency, the randomized boarding patterns help reduce the clustered crowds where infections flourish.
"When you have passengers board randomly, people are less likely to spend extended periods of time close to each other," Srinivasan said. "On the whole, random boarding does take longer, but if passengers had to choose between getting Ebola and being seated a few minutes later, we suspect they'd prefer the latter."
For example, the researchers' model suggested that, under certain circumstances and with current boarding protocols in place, an Ebola outbreak would result in a 67 percent probability of more than 20 new air-travel-related infections per month. Substituting smaller planes and better boarding strategies, that probability was reduced to 13 percent.
