The US Centers for Disease Control (CDC) was forced to pull its Ebola experts - some of the most experienced in the world - out of the eastern DR Congo just as a second wave of of the wave has been detected in the area.

The reason for the State department's caution is the fighting between militias and government troops in the east.  Experts like Dr. Pierre Rollin, who has been on the front lines on Ebola outbreaks for decades, is 1,000 miles away in Kinshasa doling out advice to the nation's health ministry.  Other CDC staffers are even further away helping countries across the eastern border prevent the spread of the virus; some aren't even on the continent, assigned to the UN World Health Organization's headquarters in Geneva, Switzerland.

The initial wave of the Ebola outbreak has killed 125 people, and now a second wave has been identified in the town of Beni, near the border with Uganda.

"We don't yet know the scale of it," said said Health Minister Dr. Oly Ilunga.  "The epicentre, which was in Mangina is now in Beni."  Dr. Ilunga added the situation is "high risk" and "worrying".

The latest outbreak is the 10th in DR Congo since Ebola was first detected there in 1976, but it's happening in an area that hasn't had an outbreak in the past.  So, health officials are starting from square one trying to educate the populace on safe practices to avoid Ebola, and it's taking some time.  Patients have run away from treatment centers, only to spread the virus further.  Relatives of someone who died of Ebola took the corpse away before it could be safely buried and risked exposure.
