Nigeria confirmed zero secondary Ebola transmissions after completing a mandatory 21-day monitoring period for 62 contacts linked to the country’s first case in over a decade, the Real Broadcasting Network reported.
The Nigeria Centre for Disease Control and Prevention said that the last of the 62 individuals was discharged from observation after showing no signs of the virus.
Imported Swiss Case Details
Nigeria recorded its first Ebola case in more than a decade on October 20, 2026, involving a Swiss woman who traveled to Uganda before returning to the Federal Capital Territory, Al Jazeera reported. Health authorities evacuated both the patient and her husband to Switzerland, where she received treatment, recovered fully, and secured hospital discharge.
Thirteen of the monitored contacts reported fevers or other non-specific symptoms during the observation window. However, laboratory tests confirmed that every one of them tested negative for the virus, according to the NCDC.
Current Surveillance Operations
Completing the initial 21-day contact monitoring cycle does not mean the outbreak is officially over, the NCDC cautioned. World Health Organization protocols require a full 42-day countdown starting from the recovery or departure of the last confirmed patient before authorities can declare an end to the outbreak.
“We will not lower our guard against possible further importation of the virus,” said Dr Jide Idris, Director-General of the NCDC. He added that the National Emergency Operations Centre remains activated at Level Three, which is the highest response tier for Ebola Virus Disease.
Festive Season Vigilance
Health officials investigated seven Ebola alerts across five Nigerian states over a three-week period, but all seven tested negative. The agency plans to sustain heightened surveillance, support infection prevention in healthcare facilities, and maintain port health measures.
“Anyone who becomes unwell, especially after travelling or possible exposure to an infectious disease, should seek medical attention early rather than assume that every fever is malaria,” Idris told the Real Broadcasting Network, urging travelers to disclose their history during upcoming December festivities.
