According to the director of CDC, Center for Disease Control and Prevention, Dr. Thomas Frieden, banning flights and closing off borders would not help contain the current Ebola outbreak and could end up driving those infected underground and lie about their conditions. Furthermore, it could further create complications like logistical problems for transportation of aids and supplies.
Ebola can be contained but it requires proper education and training of the medical staff all over the world.
A good twitter to follow at this time is also the CDC director's Twitter account as are the CDC accounts (CDC, CDC Emergency). I have found the general #Ebola stream on Twitter is filled with nonsense and does not help when it comes to getting accurate information.
I'm glad the CDC is coming forth quickly with new information. It would put to bed any rumors and unfounded innuendoes and provide up-to-date information for all.
