Nigeria Isolates Two Suspected Ebola Cases in the Northeast, Lab Results Pending

Since Nigeria confirmed its first Bundibugyo Ebola case on Oct. 20, the country has traced dozens of contacts and sent the patient home to Switzerland. Today, Oct. 31, it reported a fresh scare.

The Nigeria Centre for Disease Control and Prevention (NCDC) said in a post on X that two suspected Ebola cases have been identified in the North-East region. Both people are isolated. Contact identification and listing are ongoing, and laboratory testing is under way.

The agency was explicit about the limits. "Being classified as suspected cases does not mean they are confirmed Ebola cases; confirmation is subject to laboratory results," it said.

What the NCDC has not said

The agency has not named the states where the two people were found. It has not said whether they are connected to the first case. It has not given ages, sexes, symptoms or travel histories.

Those gaps matter. The first patient was found in Abuja, in central Nigeria. If the northeast cases are confirmed and have no link to her or to travel from Uganda or Congo, that would point to spread inside Nigeria. If they are linked to her, it would show the contact net around her was wider than known.

Neither scenario is established. The NCDC said further updates will come "as verified information becomes available."

The first case and the contact trail

The index patient is a 42-year-old woman who flew from Uganda to Abuja. The Nigerian government said she returned with symptoms on Oct. 7 and was confirmed on Oct. 20 after several days of treatment at a private hospital. According to the Swiss government, she is a Ugandan-born Swiss national and the spouse of an employee of the Swiss embassy in Uganda. Swiss officials said she had not recently been to the DRC.

She was first treated for other illnesses, including malaria, before Ebola testing was done. She and her husband were evacuated to Switzerland on Monday, Oct. 26.

Authorities first listed 44 close contacts. The NCDC later added an e-hailing driver, bringing the count of primary contacts to 54. NCDC Director-General Dr. Jide Idris told Channels Television on Oct. 26 that secondary contacts were still being identified. "We are not out of the woods yet until we are sure that we have all the contacts, and they have been followed up," he said. Removing the index patient from the country, he added, does not mean the threat is over.

Idris has also said on LinkedIn that tracing now accounts for the patient's recent movements within Nigeria. Health Minister Muhammad Pate said genomic analysis showed the virus in the Nigerian patient is closely related to the strain from Kenya's first imported case.

Uganda disputes the trail

Where she caught it is contested. The Swiss government said the infection may have occurred during a trip to Uganda about two weeks before her diagnosis.

Uganda has pushed back. Ugandan authorities denied reports of a new outbreak in their country and, according to reporting on the exchange, suggested she may have been exposed elsewhere. Uganda's health minister declared the country Ebola-free in July after the last patient was discharged. Uganda has recorded 20 confirmed cases and two deaths this year.

Without a clear source of exposure, no one can say with confidence where else the virus may be circulating undetected.

The wider outbreak

Nigeria is the fifth country to report Bundibugyo cases in this outbreak, after the DRC, Uganda, Kenya and France. As of Oct. 28, the World Health Organization counted 10,305 confirmed cases and 4,996 confirmed deaths across all affected countries. The DRC accounts for 10,274 of those cases and 4,992 of the deaths. Kenya has nine confirmed cases and two deaths. France has one imported case. Nigeria has one.

There is no approved vaccine or treatment for the Bundibugyo strain, though vaccine trials are under way. That leaves isolation and contact tracing as the main tools.

Tracing is where the DRC has struggled. Health authorities say only about 12 percent of confirmed cases there were identified among previously known contacts, and many deaths occurred in communities.

Nigeria has more than 230 million people. The first case went through several days of treatment for other illnesses before anyone tested for Ebola, and the NCDC has told all health facilities to stay on high alert and isolate suspected cases quickly.

What comes next

The next information is the lab results. If both tests come back negative, the suspected cases drop off the count and the contact list stays at 54 primary contacts. If either is positive, Nigeria will have a second confirmed case, and the NCDC will have to say where the person was infected and who they met. The agency has promised updates but has given no timeline.
