A diplomat's wife based in Abuja packed her bags for a holiday in Kampala, and that trip is now at the centre of Nigeria's first confirmed Ebola case, according to officials.
Health authorities say the woman, who was in Uganda for a vacation, is the country's first identified patient in the current outbreak. The details emerging from official channels are still limited, but the Kampala connection is now a key focus for contact tracing efforts.
What happens next, and how many people she may have been in contact with on her return, is the question everyone is watching closely.
