Diana Atwine confirmed Uganda's index case on Thursday 14 May: a 59-year-old Congolese man admitted to Kibuli Muslim Hospital on Monday 11 May who died three days later; a mobile lab has been deployed to Bwera Hospital on the DRC border.

ScienceDeveloping
Key takeaway

Uganda is running its 2022 Sudan ebolavirus playbook on a different species, again without a licensed vaccine.

Diana Atwine, Permanent Secretary at the Uganda Ministry of Health, confirmed the Kampala index case as imported on Thursday 14 May 1. A 59-year-old Congolese man was admitted to Kibuli Muslim Hospital on Monday 11 May and died on Thursday 14 May. "This is an imported case from DRC. The country has not yet confirmed a local case," Atwine said. A second Kampala case was subsequently confirmed in the Sunday WHO declaration. At least 25 contacts are under monitoring across Kampala and the Kasese border area, per the Africa CDC 16 May coordination call 2.

A mobile laboratory has been deployed to Bwera Hospital in Kasese district on the DRC border, per WHO AFRO 3. The Kasese deployment shortens the confirmation window for suspected cases arriving across the Ituri frontier from the several days needed to route samples to Kampala to the same-day turnaround INRB has been running inside DRC. Uganda has activated border screening at western entry points and along transit routes between Kasese and Kampala. The cross-border surveillance corridor with South Sudan is being expanded in parallel; South Sudan shares a 600-kilometre border with Uganda's northwest and was named in Africa CDC's 15 May grouping of at-risk states alongside DRC and Uganda.

Uganda's operational precedent is its own 2022 Sudan ebolavirus outbreak, in which 142 confirmed cases were contained in 113 days through contact tracing alone, without any licensed vaccine. Sudan ebolavirus has no Ervebo cross-protection in trial data, just as Bundibugyo has none. That 2022 containment, accomplished without a vaccine ring, is the closest operational template for what Kampala is now attempting. Atwine ran the senior coordination layer in 2022 and is running it again. The differences from 2022 are upstream: the ARILAC network gives Africa CDC a direct line into Uganda's border surveillance at greater institutional depth than three years ago, while the federal-CDC layer that supplied 2018 Equateur with embedded staff is no longer available in the same form.

Deep Analysis

In plain English

Uganda has dealt with Ebola outbreaks before, more than any other country. In 2022, Uganda stopped a 142-case Sudan Ebola outbreak without any vaccine, just by finding every person who had been near a sick person and checking them daily for three weeks. The 2022 response ran for 113 days without a single imported secondary case outside the initial district. But that 2022 outbreak started in a rural district. This one started in Kampala, Uganda's capital of four million people. A sick man from DRC travelled to Kampala, went to a hospital, and died. Now the health authorities need to find every person who may have had contact with him: at the hospital, on transport, potentially at his home. That is much harder in a big city than in a village.

What could happen next?
  • Risk

    The Kampala index case's contact footprint likely includes at least one medical facility, one or more transport routes from the DRC border, and community contacts in Kampala: potentially hundreds of contacts compared to the manageable clusters in Uganda's 2022 rural response.

  • Consequence

    A second Kampala case already confirmed in the WHO PHEIC technical assessment means community transmission has not yet been ruled out, keeping the contact footprint open-ended.

Causes and effects
This Event
Uganda runs 2022 Sudan Ebola playbook
Uganda is running the 2022 Sudan ebolavirus playbook again, a containment achieved without a licensed vaccine, against a different filovirus species the same way.
Different Perspectives
Imperial College London / Cori and Ferguson
Imperial College London / Cori and Ferguson
Anne Cori and Neil Ferguson place the case-fatality ratio at 30 to 40 per cent and read the 6.8-to-1 suspected-to-confirmed ratio as evidence that the laboratory figure understates true lethality. Many people die before a swab reaches them.
Uganda / Diana Atwine
Uganda / Diana Atwine
Diana Atwine's ministry traced the imported Kampala index case and leant on protocols rehearsed in Uganda's 2022 Sudan ebolavirus response, which contained 142 cases in 113 days without a vaccine. Nine confirmed cases now test whether that playbook holds across two districts.
United States / HHS
United States / HHS
Washington imposed a 21-day entry ban on DRC, Uganda and South Sudan nationals against WHO advice, and sought a 50-bed quarantine site in Nairobi that a Kenyan court suspended on 29 May. The posture rests on a thin federal bench with vacant senior public-health roles.
WHO / Tedros Adhanom Ghebreyesus
WHO / Tedros Adhanom Ghebreyesus
Tedros Adhanom Ghebreyesus called the outbreak 'outpacing us' on 25 May and visited Ituri on 28 May, arguing that stopping transmission depends entirely on humanitarian access. WHO opposes any restriction of travel to or trade with DRC or Uganda.
Africa CDC / Jean Kaseya
Africa CDC / Jean Kaseya
Jean Kaseya declared the continental emergency before WHO and opposed the US travel ban as punishment by passport rather than by exposure. The Africa CDC raised nearly $500 million in days and frames the response as African-led, coordinated from Addis Ababa rather than waiting on Geneva.
European Union / ECDC
European Union / ECDC
ECDC activated an EU Health Task Force, assessed European Bundibugyo import risk as very low, and flagged the recombinant clade Ib/IIb mpox strain in four countries as a surveillance watch item. Both calls reflect the same post-2024 IHR mandate: ECDC acts as a continental early-warning layer rather than waiting for WHO Disease Outbreak News guidance.
