ABUJA, Nigeria — Sixty-two people identified as contacts of Nigeria’s imported Ebola case were expected to complete their scheduled follow-up between October 31 and November 13, according to an October 29 situation report from the Nigeria Centre for Disease Control and Prevention.
The agency said the contacts had been identified, categorized and placed under follow-up. None had tested positive as of the report date, while contact tracing and epidemiological investigations remained active.
November 13 represents the latest projected completion date for the 62 contacts known to authorities on October 29. It is not a guaranteed end date for the broader surveillance operation, particularly if investigators identify additional contacts or obtain new epidemiological information.
The European Centre for Disease Prevention and Control separately confirmed that Nigeria had 62 contacts under follow-up as of October 29. The European agency also said further tracing and investigation were continuing.
Testing finds no positive contacts
Nigeria’s public health agency reported that 18 samples had been tested by October 29. One sample, taken from the index patient, was positive. The remaining 17 were negative, including 15 samples collected from contacts and two from people treated as suspected cases.
The results meant no positive contact had been detected by the reporting date. However, officials continued monitoring the identified group rather than treating the negative results as the conclusion of the response.
The NCDC said additional contact tracers had been mapped and trained to support the operation. Authorities also planned to assess more contacts to determine whether any should be moved to a quarantine facility.
At the time of the October 29 report, the agency assessed known exposure as being limited to one epidemiological cluster directly connected to the confirmed patient. That finding described the available evidence at that point and did not rule out the possibility that further contacts or transmission could later be identified.
Case confirmed in the Federal Capital Territory
Nigeria’s National Reference Laboratory confirmed Ebola disease caused by Bundibugyo virus in the Federal Capital Territory on October 20. The patient was a 42-year-old woman who had travelled from Uganda to Abuja through Addis Ababa.
She arrived in Abuja on October 3 and developed symptoms on October 7, according to the official account. She was admitted to a private health facility on October 11. The NCDC was notified of the suspected case on October 19, one day before laboratory confirmation.
The patient was medically evacuated from Nigeria to Switzerland on October 26. In its October 29 report, the NCDC described her as clinically stable. The European disease control agency said she was receiving treatment at Geneva University Hospital.
The combination of international travel, treatment at a private facility and the interval between symptom onset and official notification prompted a contact-tracing response focused on people linked directly to the patient. The 62 identified contacts were categorized so health officials could organize monitoring and testing based on the investigation.
Projected dates require careful interpretation
The NCDC’s timetable showed that completion dates for the identified contacts varied, beginning October 31 and extending to November 13. That range reflects separate follow-up schedules rather than a single nationwide deadline.
As a result, monitoring for some people could conclude before November 13, provided their scheduled follow-up was completed and no new concerns emerged. The later date applied to the final expected completion among the 62 contacts recorded in the October 29 report.
The continuing investigation also means the number of people under observation could change. Any newly identified contact would have an individual follow-up schedule that might extend beyond the dates set for the original group.
For now, the official findings through October 29 showed one laboratory-confirmed imported case, no contacts testing positive and one known cluster tied directly to the index patient. Nigerian authorities continued tracing, monitoring and assessing contacts while laboratory testing supported the wider public health response.
