Nigeria ends Ebola contact monitoring with no secondary transmission

Nov 13, 2026

On November 13, 2026, the Nigeria Centre for Disease Control and Prevention concluded its 21-day monitoring period for 62 contacts linked to the country's first Ebola case in over a decade, with no secondary transmissions reported. The index case involved a Swiss woman diagnosed on October 20 after travel to Uganda, who has since recovered in Switzerland. Although all contacts and seven state alerts tested negative, WHO protocols require a 42-day countdown before an official end to the outbreak.

Contact monitoring and symptom testing results

  • ▪Thirteen monitored contacts reported fever or other non-specific symptoms during the 21-day observation period, but all 13 tested negative for the Ebola virus
  • ▪The Nigeria Centre for Disease Control and Prevention completed the 21-day monitoring period on November 13, 2026, for all 62 contacts linked to Nigeria's reported Ebola case without any falling ill

Initial case diagnosis and patient evacuation

  • ▪The Swiss woman diagnosed with Ebola in Nigeria on October 20, 2026, and her husband were evacuated to Switzerland, where she fully recovered and was discharged from the hospital
  • ▪Nigeria confirmed its first Ebola case in over a decade on October 20, 2026, in a Swiss woman who had traveled to Uganda before returning to Nigeria

Ebola alerts and response

  • ▪An official of the Nigeria Centre for Disease Control and Prevention prepared an ambulance for deployment for a suspected Ebola case outside the agency's headquarters in Abuja on October 25, 2026
  • ▪The Nigeria Centre for Disease Control and Prevention investigated seven Ebola alerts across five Nigerian states between October 23, 2026, and November 13, 2026, with all seven alerts testing negative

Requirements and status for ending outbreak

  • ▪The Nigeria Centre for Disease Control and Prevention stated that finishing the 21-day contact monitoring period does not automatically signify that Nigeria's Ebola outbreak has ended
  • ▪Under World Health Organization protocols, a country must complete a full 42-day countdown following the recovery or departure of the last confirmed patient before declaring an official end to an outbreak
