Preventing future outbreaks like Ebola

President Barack Obama sent 3,000 troops into affected areas to combat the Ebola outbreak as it continues to spread in western Africa.

In the latest effort to stop the virus, Sierra Leone ordered a three-day lock down.

The head of the Emergency Operations Center leading Sierra Leone's Ebola response, Stephen Gaojia, called the lockdown "a huge success," Reuters reports. About 123 people had contacted authorities by Sunday morning thinking they might be infected; 56 tested positive for the virus, 31 negative and 36 were still awaiting results. Final numbers will only be released once information is compiled from around the country.

The lockdown was one of the most aggressive containment strategies to be employed so far in the growing effort to contain the worst Ebola outbreak in history, which has killed more than 2,600 people across West Africa. Sierra Leone ordered its six million residents to stay indoors for three days, while 30,000 health workers, volunteers and teachers circulated, educating households on how to prevent the spread of the disease.

On The Daily Circuit, we examine what's making this specific outbreak so hard to tackle, but also look at a bigger picture view of how we got here. What is missing in countries that allowed the crisis to spread, and what can be done on a local level to prevent this kind of epidemic in the future?
