The outbreak of the deadly Ebola virus in Africa is so out of control that airlines are now banning anyone with flu like symptoms from boarding planes.

A simple fever is cause to be prohibited from boarding any flight from nations that are confirmed to have an outbreak of the virus.

“It’s probably one of the more complicated outbreaks because it is occurring in a very densely-populated urban area, unlike previous outbreaks,” Dr. Tim Jagatic of Doctors Without Borders told NBC.

Dr. Sanjay Gupta of CNN traveled to Conakry, Guinea and said the flight into the country was nearly empty as were hotels.  The outbreak in the city has caused hundreds of thousands to flee into the rural areas.  However, the rural part of the country is where the outbreak first began months ago.

The Guinea health ministry, however, is cautiously optimistic they have the outbreak now under control after reporting significantly fewer deaths from the virus during the last week.  106 of the 159 confirmed or suspected victims of the virus have died since the beginning of the outbreak.

The World Health Organization said it could take two to four months to truly control the outbreak.

The U.S. Department of Defense has opened a laboratory in neighboring Liberia because of an increase in Ebola cases connected to the Guinea strain.
