Ebola is a "dread disease" - an extremely contagious epidemic disease which spreads very rapidly, and has an extremely high mortality rate (depending on strain, as high as 99-100%). There is NO cure, although with critical care treatment there is a chance of survival if caught in time, correctly diagnosed. Ebola epidemic can wipe out the population of a major city within weeks, and with so much travel these days, an epidemic can spread worldwide from just ONE infected person.
Health authorities can order quarantine with the highest level of isolation & protection (wearing biohazard suits), order medical evacuation of persons within some specified radius around an infected person/home/area. If evacuated, find a place to stay - relative, friend, hotel, whatever. Your homeowner's or renter's insurance might reimburse your hotel costs if you have the right coverages & nowhere else to stay. Do not expect health agencies to pay your way, find you a place, etc. In such a major medical disaster, all they do is force you out of the area & you take care of yourself. There is no way there is sufficient govt housing, money, or anything else to take care of anyone other the sick person & those directly exposed to that person. The hospital care for the African illegal alien in Texas who brought in the first ebola case to US cost well over a million dollars.
You ALWAYS must have an emergency fund and an emergency plan. Hurricane, tornado, flood & other natural disasters are not the only things that can happen & affect you. Medical/epidemic disasters, house fire - the world is full of dangers & your survival in case of any sort of disaster is really up to you.
