David D’Eugenio, founder of the HomeSafety Academy, conducts a class on the threat of Ebola and what to expect if it becomes widespread in the United States, in Lake Park, Florida on October 21, 2014. The fear over Ebola has meant a rush of students, about 54 in the past two weeks, to take a primer course on how to avoid contracting the virus, said D’Eugenio.
