Nigeria Must Complete 42-Day Monitoring Before Being Declared Ebola-Free — WHO
The World Health Organization (WHO) has said Nigeria must complete a 42-day surveillance period before it can be officially declared free of Ebola, despite the medical evacuation of the country’s confirmed patient to Switzerland.
Dr. Chikwe Ihekweazu, Executive Director of the WHO Health Emergencies Programme, disclosed this during an interview with ARISE News on Wednesday, October 28, 2026.
He explained that health authorities must continue monitoring the 53 people identified as contacts of the infected patient to ensure that no additional cases emerge.
According to Ihekweazu, the process involves monitoring exposed individuals for 21 days, followed by another 21-day observation period before Nigeria can receive an official all-clear.
The WHO official stressed that the absence of an active Ebola patient in the country does not automatically mean the risk of further transmission has been eliminated.
Why Nigeria Must Wait 42 Days
Ihekweazu explained that the monitoring period forms part of established WHO procedures for controlling Ebola outbreaks and preventing further infections.
Ebola has an incubation period of between two and 21 days, meaning an infected person may not develop symptoms immediately after exposure.
Health authorities must therefore observe identified contacts during the incubation period and continue surveillance to establish that transmission has stopped.
The additional observation period is intended to provide greater assurance that no further infections have occurred.
The WHO official said the procedures are applied internationally when countries respond to Ebola outbreaks.
He emphasized that even a single confirmed case requires coordinated public health measures because of the serious risks associated with the disease.
53 Contacts Identified as Surveillance Continues
Nigeria’s Ebola response initially identified 44 contacts following confirmation of the imported case in the Federal Capital Territory on October 20.
The number was subsequently updated to 53 as investigations and contact tracing progressed.
According to the Nigeria Centre for Disease Control and Prevention (NCDC), the identified contacts include healthcare workers, domestic staff and the patient’s spouse.
Following the patient’s evacuation, 52 contacts remained in Nigeria under surveillance, while Swiss health authorities assumed responsibility for monitoring her husband.
Contact tracing involves identifying people who may have been exposed to an infected individual, assessing their level of risk and monitoring them for symptoms.
The identification of 53 contacts does not mean that those individuals have contracted Ebola.
Rather, the surveillance exercise is designed to detect any possible infection early and allow health authorities to respond before further transmission occurs.
Ebola Patient Evacuated to Switzerland
The confirmed patient, a Swiss woman who had travelled from Uganda to Abuja, was medically evacuated to Switzerland on October 26 after receiving treatment in Nigeria.
The woman was reported to be clinically stable following medical care provided by Nigerian healthcare professionals.
Her husband, a Swiss diplomat who had been identified as one of her contacts, also travelled to Switzerland for monitoring.
Following their departure, WHO Regional Director for Africa, Dr. Mohamed Janabi, said Nigeria had no known active Ebola cases.
However, he emphasized that surveillance and containment measures must continue.
Ihekweazu also clarified that the medical evacuation did not result from inadequate treatment facilities or a lack of medical expertise in Nigeria.
He said the transfer was arranged at the request of the patient’s country of origin.
The development means Nigeria currently has no known Ebola patient receiving treatment within its borders, but it has not yet completed the monitoring required for an Ebola-free declaration.
WHO Commends Nigeria’s Ebola Response
Ihekweazu praised Nigerian health authorities for their response to the imported infection, particularly the speed of laboratory confirmation, genetic sequencing and patient management.
He said the country had implemented appropriate public health measures with support from the WHO.
The response has involved the Federal Ministry of Health and Social Welfare, the NCDC and other agencies responsible for disease surveillance and emergency preparedness.
The NCDC has continued coordinating contact tracing, infection prevention measures and surveillance activities.
Ihekweazu said the immediate priority was to ensure that every identified contact receives appropriate daily follow-up.
He explained that any new infection must be detected quickly so that health authorities can respond and prevent wider transmission.
WHO Says No Restrictions on Public Gatherings
Addressing concerns about political rallies and other public gatherings, Ihekweazu said the WHO had not recommended restrictions on gatherings in Nigeria because of the confirmed Ebola case.
He explained that the organization’s recommendations are guided by public health assessments rather than political considerations.
The WHO official urged Nigerians to cooperate with health authorities and avoid turning the Ebola response into a political controversy.
He maintained that the focus should remain on surveillance, early detection and preventing further infections.
The clarification comes as Nigeria prepares for increased political activities ahead of the 2027 general elections.
Ebola Outbreak Raises Concerns Across Africa
Nigeria’s surveillance efforts are taking place amid a wider Ebola outbreak affecting parts of Africa.
During the interview, Ihekweazu discussed the situation in the Democratic Republic of the Congo, where thousands of cases and deaths have been reported.
The outbreak has increased concerns about cross-border transmission and the need for stronger disease surveillance across the continent.
Public health authorities have continued to emphasize the importance of early diagnosis, contact tracing, infection prevention and coordinated responses between countries.
Nigeria’s previous experience with Ebola in 2014 demonstrated the importance of rapid public health intervention.
That outbreak was contained through coordinated contact tracing, isolation and surveillance measures.
The current response similarly depends on identifying possible exposures and ensuring that any additional infections are detected promptly.
What Nigerians Should Know
Ebola is a serious viral disease that spreads mainly through direct contact with the blood or other body fluids of an infected person who is showing symptoms.
Symptoms can include fever, severe weakness, headache, vomiting and diarrheic.
People who believe they may have been exposed should contact public health authorities for guidance and monitoring.
Anyone who develops symptoms after possible exposure should avoid close contact with others and seek instructions from health officials before visiting a healthcare facility.
For now, the WHO says Nigeria must complete the required monitoring period before receiving an official Ebola-free declaration.
The next several weeks will therefore remain important as the NCDC and its partners continue surveillance of identified contacts.
