Late and slow international response, the absence of solid leadership as well as the lack of treatments and vaccines are a recurrent scenario in many of today's health emergencies and are not unique to the Ebola epidemic, the medical charity said.

"If a global pandemic were to strike tomorrow, there is still no well-resourced, coordinated international response in place to kick in," Joanne Liu, the international president of Médecins Sans Frontières (MSF), said in a statement on Wednesday.

In the 3 days prior to Nigeria's official announcement about Ebola, Twitter users had already shared around 1,500 tweets about the outbreak....

Dr. David Nabarro stressed in an interview with The Associated Press on Monday that the Ebola epidemic "absolutely isn't over" though Liberia has been Ebola free since May 9.
