No, it is rising exponentially. This has the potential for killing 1/2 of the worlds population. The 3rd world countries will be decimated.
And I'm not convinced that it is only spreading because of the poor conditions in Africa. It can survive on a door handle from a sweaty hand, a cough, etc. Just as our better sanitary conditions don't stop the spread of a cold. In fact, a person in a small town in Liberia may travel 5 blocks walking from home to work, the market, etc. How many in the U.S. take the bus, then the train and the elevator going 20 miles in a day?
Our treatment may be better, but not if all of the hospitals and clinics are full. Emergency rooms are already crowded most times of the day. Minnesota has a bit over 10,000 hospital beds for the entire state. Add in temporary places run by local clinics, national Guard, etc. that might jump to 30,000?
