There's a new phase of Ebola in Liberia. Epidemiologists call it pingponging.
Back in March, the disease was found in the rural areas. Then as people came to the capital to seek care, it started growing exponentially there. Now, some sick people are going back to their villages, and the disease has pingponged to the rural areas again.
So that's where we're headed — into the hot, thick jungle of Liberia to investigate a new Ebola hotspot.
