    The Ugandan Ministry of Health declared a yellow fever outbreak earlier this month after laboratory confirmed cases were reported from Koboko and Masaka districts.

    The patients are an 80-year-old woman and a 10-year-old girl. Neither had a history of yellow fever vaccination, nor exhibited symptoms of jaundice, however the older woman had hemorrhagic signs.

    On 14 May 2019, the Ugandan Ministry of Health notified WHO of a yellow
    fever outbreak in two separate districts Koboko and Masaka located in the
    Northern and Central region of the country respectively. The yellow fever
    outbreak was declared in-country on 6 May 2019 following laboratory
    confirmations from the regional yellow fever reference laboratory, the
    Uganda Virus Research Institute (UVRI).

    In March 2019, two samples collected from different districts as part
    of the routine viral haemorrhagic and the sentinel acute febrile Illness
    (AFI) surveillance programme tested positive for yellow fever by both
    serology (IgM) and plaque reduction neutralization test (PNRT). The
    first sample was collected on 1 March 2019 from an 80-year-old female
    from a village in Koboko District and the second sample was collected
    on 21 March 2019 from a 10-year-old female student from a second
    village in Masaka District. Both cases presented with symptoms of fever,
    malaise and joint pain. Neither had a history of yellow fever vaccination,
    nor exhibited symptoms of jaundice, however the older woman had
    hemorrhagic signs.

    Following the confirmation of the two cases, a district rapid response
    team was sent to the affected localities to conduct further investigation.
    The team sampled several households and found a substantial population
    of unvaccinated individuals due to immigration and missing the yellow
    fever reactive vaccination campaign, which was conducted in 2016.
    Seven additional samples were collected from suspected cases who met
    the case definition for yellow fever.


    A rapid response team was deployed to Masaka for further
    investigation. Response activities undertaken included enhanced
    surveillance, entomologic surveys, and active case search in both
    Masaka and Koboko.

    Samples collected from suspected cases were shipped and tested
    at the arboviral laboratory in Uganda Virus Research Institute

    A national rapid response team (formed jointly by the Epidemiology
    and Surveillance Division, the Public Health Fellowship Programme
    and UVRI) was constituted and dispatched to the affected districts
    to conduct further investigations to support the response activities.

    The district surveillance team in Masaka opened an alert desk to
    receive and follow up any alerts.

    A community yellow fever case definition has been provided
    to community members who are advised to report to the health
    facility for further assistance if needed.

    Risk communication to sensitize the populations on preventive
    measures against yellow fever are being conducted in the affected


    Uganda is designated as a high-risk country in the Eliminate Yellow Fever Epidemics (EYE)
    strategy with a history of recent outbreaks in 2010 and 2016. The country has not yet
    introduced the yellow fever vaccination into the routine immunization programme and the
    last reactive yellow fever vaccination campaign was conducted in 2016 with coverage in
    three districts including of Kalangala, Masaka and Ruukunguri. One of the affected district
    during this outbreak, Koboko district, is located along the border with the Democratic
    Republic of the Congo and South Sudan and the presence of the vector in the affected
    areas, as well as frequent population movements between the countries, presents the
    potential for international spread of the outbreak. Thus, cross border surveillance has
    been heightened alongside the ongoing Ebola virus disease preparedness activities in
