Airplane disease transmission!

Researchers at Florida State University, funded by NSF, studied how infectious diseases spread in airplane cabins, especially during the 2014 Ebola outbreak. Using advanced simulations, they found that current boarding procedures contribute to disease transmission. They propose a two-zone boarding system to minimize infection spread, which could be crucial during epidemics.
