When the Tonkolili District reported a new case of Ebola on 24 July 2015, it marked a change in the Sierra Leone Ebola response.

A rapid response team was despatched to manage this new source of infection, the first case in that area for more than 150 days. It resulted in a whole village being quarantined, and showed how quickly Ebola can travel and that no district can let down its guard until there are zero cases of Ebola.
