The Centers for Disease Control and Prevention upgraded its travel advisory for West Africa Thursday because of the raging Ebola outbreak, saying people should avoid nonessential travel to Guinea, Liberia, and Sierra Leone.
"This Level 3 travel warning is a reflection of the worsening Ebola outbreak in this region," CDC said in a statement.
"“This is the biggest and most complex Ebola outbreak in history. Far too many lives have been lost already,” said CDC Director Dr. Tom Frieden. “It will take many months, and it won’t be easy, but Ebola can be stopped. We know what needs to be done. CDC is surging our response, sending 50 additional disease control experts to the region in the next 30 days.”
