Kenya has confirmed a third case of Ebola after a 65-year-old woman tested positive while in quarantine.

The woman is a close relative of Kenya’s first confirmed patient, a 40-year-old who died from Ebola on 5 October, two days after arriving in Kenya from the Democratic Republic of the Congo (DRC).

The Associated Press (AP) reported that the woman had been in quarantine since 6 October and developed symptoms before testing positive. She has since been transferred to an infectious disease unit for treatment.

The second patient, a 39-year-old man from the same family, remains stable, according to Kenya’s Ministry of Health.

The ministry said there was no evidence of community transmission, as all three cases were linked to the first patient and the individuals had been in quarantine.

Nigeria’s preparedness

The development comes as Nigeria continues to monitor the regional outbreak and strengthen preparedness against possible importation of the virus.

PREMIUM TIMES reported on 7 October that the Nigeria Centre for Disease Control and Prevention (NCDC) was reviewing the country’s preparedness after Kenya confirmed its first imported case of the Bundibugyo strain of Ebola.

In a statement issued on 6 October, the NCDC said the case highlighted the risk of international importation through travel and population movement, including the possibility of the virus entering Nigeria.

The agency said it was working with the Federal Ministry of Health and Social Welfare, Port Health Services, state governments and other partners to strengthen surveillance, early detection, laboratory diagnosis, isolation, contact tracing and infection prevention.

It also said Nigeria conducted a national Ebola preparedness simulation exercise to assess its readiness to respond to a possible case.

As of 6 October, the NCDC said Nigeria had no confirmed Ebola case.

Contact tracing continues

Kenya’s first case involved a 40-year-old man who had been living in the DRC and travelled through Uganda before arriving in Nairobi. He tested positive for Ebola and died on 5 October.

The confirmation of a second case on 14 October raised concerns about further infections among people exposed to the initial patient.

PREMIUM TIMES reported on 14 October that the second patient, a 39-year-old close relative of the first case, developed symptoms while in quarantine.

At the time, Kenyan authorities had identified 128 contacts linked to the first patient, with 113 located and efforts ongoing to trace the remaining 15.

In its report on Friday, AP said three contacts of the initial patient remained unaccounted for, while authorities continued efforts to trace people who might have been exposed.

The latest case brings the number of confirmed Ebola infections in Kenya to three. 

Regional outbreak

The cases in Kenya are linked to the ongoing Ebola outbreak in the DRC, where the Bundibugyo virus has caused thousands of infections and deaths.

The World Health Organisation (WHO) said the DRC had recorded 7,890 confirmed cases and 3,799 deaths as of 23 September.

The outbreak has raised concerns about cross-border transmission, particularly as people travel between affected areas and neighbouring countries.

The Bundibugyo virus is a distinct species of Ebola virus. No vaccine or treatment has been specifically approved for this strain.
