Two people in northeast Nigeria, reported as suspected Ebola cases on Saturday, were cleared by tests that day, the disease agency said. Nigeria’s only confirmed case remains the woman found in Abuja on 20 October.
Nigeria’s disease control agency announced two suspected Ebola cases in the northeast on Saturday 31 October 2026. Later that day it said both people tested negative after two rounds of testing, so Nigeria still has one confirmed case.
The agency is the Nigeria Centre for Disease Control and Prevention (NCDC), the federal body that tests, tracks and announces Ebola cases. For US readers, the result matters because Nigeria confirmed an Ebola case on 20 October.
What the Disease Agency Said on Saturday
NCDC first announced on Saturday that two suspected cases had been identified in the northeast, without naming a state. It said the two were isolated, contact tracing had begun and tests were under way.
It told Nigerians not to treat the two as confirmed cases until results came back. It urged people to keep good hygiene and follow health guidance.
NCDC Director-General Jide Idris said that evening: “Fortunately, the samples turned out negative for EVD after two rounds of testing.” EVD stands for Ebola virus disease.NCDC said there is no laboratory-confirmed Ebola case in Adamawa State.
It added that the woman confirmed in Abuja on 20 October remains Nigeria’s only confirmed case.
Nigeria’s One Confirmed Case
NCDC’s 29 October situation report says a 42-year-old woman arrived in Abuja from Uganda on 3 October after travelling via Addis Ababa. The National Reference Laboratory confirmed Ebola on 20 October.
She was flown to Switzerland on Monday 26 October after her country asked for her return. She was clinically stable when the 29 October report was issued.
As of 29 October, NCDC counted 62 contacts linked to her, all in one cluster. Follow-up is due to finish between 31 October and 13 November.
The same report says 18 samples had been tested and one was positive. It also logs one suspected case from Enugu that tested negative in the previous 24 hours.
Ebola is a severe viral illness that spreads through direct contact with the blood or body fluids of a sick person. Bundibugyo is one of its species, and it caused the Abuja case.
The Wider Outbreak and US Travel Rules
The wider outbreak centres on the Democratic Republic of the Congo, with 10,274 confirmed cases and 4,992 related deaths by 29 October. The figures come from ECDC, the European Union’s disease-prevention agency, in its update of 30 October.
ECDC also lists nine confirmed cases and two deaths in Kenya as of 26 October. It says Uganda’s outbreak has ended.
The US Centers for Disease Control and Prevention (CDC) updated its Ebola travel page on 30 October. Its entry rules name the Democratic Republic of the Congo, Uganda and South Sudan, not Nigeria.
After 11:59 p.m. Eastern on 3 November, passengers on any international flight to the US must sign a declaration. It says they have not been in the Democratic Republic of the Congo in the previous 21 days.
What Prediction Markets Say
Polymarket, where users bet real money, gives about 2.6% odds that the World Health Organization calls Ebola a pandemic in 2026. Trading in that market totals about US$809,000, and the price barely moved in the past week.
A separate Polymarket bet gives about 15% odds of a confirmed Ebola case in the United States in 2026. That market has only about US$11,500 in trading, so its price is thin.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
What It Means for You
The CDC page updated on 30 October does not list Nigeria among its entry-restriction countries. Travellers to Nigeria should check it again before flying, because the rules can change.
The 62 people under follow-up are contacts of one patient, not the general public. NCDC says all known exposure is confined to that single cluster.

What Is Not Known
The NCDC statements seen so far do not name the two people, and this report does not guess at who they are. Claims about their jobs and recent travel have circulated, but NCDC has not confirmed them.
NCDC has not published a contact count for the two suspects or named the laboratory. Follow-up on the 62 contacts of the Abuja patient is unfinished, so that count may change.
