Nigeria's Federal Government has confirmed an Ebola case in Abuja. The infected person had recently arrived from Uganda on an international flight. Health authorities have identified 44 contacts linked to the patient. Those people are the focus of efforts to determine whether the virus was passed to anyone else. Officials are also asking passengers on the same flight to cooperate with the public-health response. The appeal is meant to help investigators locate possible exposure points and assess the risk of further spread. The case has placed contact tracing and airport health procedures at the center of Nigeria's response.
