Americans barred from returning home amid Congo Ebola outbreak

The Trump administration has placed US citizens in the Democratic Republic of Congo on a "do-not-board" list, requiring them to spend 21 days in a third country before they can return home amid an active Ebola outbreak. The measure effectively strands American citizens abroad without a direct path home, a highly unusual use of public health powers that raises immediate legal and humanitarian questions. The 21-day quarantine threshold matches the maximum incubation period for the Ebola virus.
