Trump announced Wednesday that there would be a ban on incoming travel from Europe going into effect on midnight Friday, shocking the EU and sending many people into a panic as they tried to determine what that would mean for Americans and Permanent Residents currently abroad. As it stands, it doesn't appear that Americans, Permanent Residents, and military will be affected, although both Trump and Pence have reported that those who are returning will have to undergo screening and possible quarantine.
Not all European countries will be restricted. Restrictions have been placed on: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, and Switzerland.
On Thursday, there was speculation that even a domestic travel ban might not be out of the question, with Trump stating in his usual ineloquent manner: "Is it a possibility? Yes. If somebody gets a little bit out of control, if an area gets too hot."

*Not everyone in the US is able to take time from work without losing wages and they will have to go to work despite their own illness or the possibility of contracting disease from others, but certain companies such as Darden (parent company of Olive Garden) and others are extending sick leave to all employees. Hopefully, other companies will follow suit.
