Ebola Spreads

How did a health worker in Dallas wearing full protective gear catch Ebola if the virus “does not spread easily”? Just last week, Barack Obama declared to the public that you cannot get Ebola “sitting next to someone on a bus”, and yet a nurse in protective gear that was taking extreme precautions to avoid being exposed to the disease has just caught it. The head of the CDC says that there must have been a “breach in protocol” somewhere, because of course the CDC guidelines regarding the transmission of this virus could never be wrong.
