Kenyan health authorities say quarantine and contact-tracing measures have enabled the early detection of Ebola infections linked to the country’s first confirmed case, as the number of confirmed infections has risen to three.
The latest case was confirmed on Friday, October 16, involving a 65-year-old woman who is a close relative of the first two patients. She had been in quarantine since October 6 and was transferred to an infectious disease unit after developing symptoms.
The development follows the confirmation of a second case on October 14, involving a 39-year-old man who was already under quarantine and daily monitoring when he developed symptoms on October 13.
According to Kenya’s Ministry of Health, the man developed fever, fatigue, and joint pains. He was immediately isolated and tested, with laboratory results confirming Bundibugyo virus disease, the strain responsible for the current outbreak. Samples tested positive at both the National Virology Reference Laboratory and the Kenya Medical Research Institute (KEMRI)-CDC laboratory.
The patient was transferred to a designated treatment centre, where he is receiving supportive care. The Ministry said early detection and isolation helped limit opportunities for further transmission.
Contact Tracing and Quarantine Measures
The second case was identified among close family contacts of the first patient, who died on October 5 after arriving in Nairobi from the Democratic Republic of Congo (DRC).
In its October 14 update, the Ministry said it had identified 128 contacts linked to the first case. By October 13, 113 had been traced, including 108 who were in quarantine in Kenya. Five others were outside the country, with the relevant health authorities notified under the International Health Regulations (2005).
At that stage, efforts to locate the remaining 15 contacts were ongoing, alongside assessments of people who had interacted with the second patient after his symptoms began, including healthcare workers and quarantine staff.
By October 16, Reuters reported that authorities had accounted for 127 of 130 people identified as contacts of the first patient, with efforts continuing to locate the remaining three. The revised figure reflects a subsequent update in the tracing effort.
All identified contacts are being monitored for symptoms, with quarantine and clinical checks intended to continue for 21 days after their last possible exposure.
No Evidence of Wider Community Transmission
Despite the three confirmed cases, health authorities have reported no evidence of transmission in the wider community. All three infections are linked to the first patient, and the second and third patients had already been in quarantine when their symptoms developed.
The Ministry has strengthened infection prevention and control measures at quarantine facilities and treatment centres, while health workers have been instructed to use appropriate protective equipment and follow strict safety procedures.
Authorities say anyone identified as a contact who develops symptoms must be isolated and tested immediately.
Regional Health Surveillance Remains Critical
Kenya’s cases are linked to the ongoing Ebola outbreak in the DRC, where the Bundibugyo strain has caused thousands of infections and deaths. The first Kenyan patient had been living in the DRC before travelling through Uganda and arriving in Nairobi on October 3. He subsequently tested positive and died on October 5.
The infections have renewed attention on cross-border health surveillance, travel screening and coordination between neighbouring countries.
Kenyan authorities have intensified screening at airports and border crossings, including additional measures for travellers arriving from countries associated with the outbreak.
The Bundibugyo strain currently has no approved vaccine or specific treatment, making early detection, supportive medical care, isolation and contact tracing central to efforts to contain its spread.
With three confirmed cases and one death reported as of October 16, Kenya’s response remains focused on identifying all contacts, monitoring those at risk and preventing further infections.
The Ministry continues to urge vigilance and cooperation with public health teams as surveillance and containment measures are strengthened.
