The well documented outbreaks of the Ebola Virus Disease have only produced human fatalities upon the African continent. The reason for this stems from the animals that thrive in the African environment, the delicate interspecies interactions, and the poverty and customs of the African people.
There has never been a reported case of Ebola in the United States, so unless you have recently been to Africa, your chances of contracting Ebola is zero.
I hope that this statistical information will ease your mind.
The very best to you, WC!... Chuck
