Twenty years ago, the Ugandan town of Bundibugyo faced down a deadly Ebola outbreak. Now, the virus strain bearing its name has returned, not in Bundibugyo itself, but just across the border in eastern Congo. This resurgence is halting life and trade on a vital, busy frontier. Authorities are on high alert, implementing strict new measures to contain the spread. The world watches as a community, once ravaged, now stands ready to beat back the ghost of its past.
