Have you traveled overseas? The US is so so very much cleaner than all the filthy places. We separate cooking from eliminating and showering. We constantly wash everything. Ebola won’t have a chance here.
Not everyone in the US live in your bubble. Especially if they are immigrants living in these “ethnic communities.” Old ways die hard.
1. What about the hordes of refugees and illegals all over the country? They bring with them their health and sanitation practices from their homelands.
2. Children in over-crowded classrooms with poor ventilation, almost impossible to keep from sharing things.
3. There's going to be more than one disease to deal with...flu, the Entero virus that's new and exciting, and possibly Ebola. What's going to happen when some people get more than one of them at the same time?
Our best hope is that Ebola is a disease that's based on the climate where it thrives, and won't be deadly in most of the US.
