The only problem is they have been saying that the initial symptoms mimic a double handful of other maladies - it might be easy enough to have a number slip through unless all of those with any symptoms for a variety of maladies are treated as Ebola cases until proven different. One or two people slipping through the cracks can easily start a number of new hot spots.
This runs into a different problem for Ebola. From onset of symptoms and ability to infect others, to death is typically only 10 days.
“Signs and symptoms of Ebola usually begin abruptly with an influenza-like stage characterized by feeling tired, fever, headaches, and joint, muscle, and abdominal pain. Vomiting, diarrhea and loss of appetite are also common. Less common symptoms include: sore throat, chest pain, hiccups, shortness of breath and trouble swallowing.
“Skin manifestations may include a maculopapular rash (in about 50% of cases). Early symptoms of EVD may be similar to those of malaria, dengue fever, or other tropical fevers, before the disease progresses to the bleeding (hemorrhagic) phase.”
Importantly, from the 10 day symptoms to mortality, you need to subtract the bleeding and incapacitation days, as unless people congregate around them, and they do not receive any medical attention, they are far less likely to transmit the disease.
Then consider active medical pursuit and effort to isolate anyone who is infected, and there is a fairly small window for others to be infected, and yet escape medical quarantine.
