    EVENT DESCRIPTION

    On 17 January 2020, the Ministry of Health and Sanitation of
    Sierra Leone notified WHO of a confirmed Lassa fever case in Kono
    district, which is bordering the Republic of Guinea to the east. The
    case-patient, an 8-year old girl from Kangama town, Kono district,
    presented to the Kangama Community Health Centre on 12 January
    2020 with a fever of 38.1?C and vomiting. Following a positive Rapid
    Diagnostic Test for malaria on her initial visit, she was treated with
    antimalarial drugs and rehydrated. However, the disease eventually
    progressed in the subsequent days and she was referred from the
    Kangama community Health Centre to the paediatric isolation ward
    at Kono district hospital on 14 January 2020 with high-grade fever
    and vaginal bleeding. The patient died shortly after her admission.
    A blood specimen collected on arrival at Kono district hospital was
    sent to the Lassa fever Kenema Reference Laboratory and tested
    positive for Lassa fever by reverse transcription polymerase chain
    reaction (RT-PCR).

    Between 30 October 2019 and 17 January 2020, a total of nine
    suspected Lassa fever cases including five deaths was reported
    in three districts: Tonkolili (five cases with three deaths), Kenema
    (three cases with one death) and Kono (one case with one death).
    Of these nine suspected cases, five were laboratory confirmed
    for Lassa fever (three in Tonkolili and two in Kenema districts).
    Investigations established that there is no epidemiological link
    between the recently confirmed Lassa fever case in Kono district
    and the two clusters identified in Tonkolili and Kenema districts.
    Liberia and Nigeria are currently experiencing Lassa fever outbreaks
    as well, with no links to the transmission chains in Sierra Leone.

    PUBLIC HEALTH ACTIONS

    On 17 January 2020, the Director of Health Security and
    Emergencies at the Ministry of Health and Sanitation of Sierra
    Leone convened a meeting with partners to formally release
    information on the recently reported Lassa fever confirmed case
    in Kono district.

    A safe burial was conducted on 15 January 2020, under the
    supervision of the Kono District Health Management Team, to
    prevent exposure of the case family members and the community
    to the Lassa fever virus.

    Surveillance has been enhanced in Kono district, including active
    case search, identification and follow-up of contacts. A total of
    32 contacts have been identified and are being monitored for a
    duration of 21 days.

    Infection Prevention and Control measures are being strengthened
    in the community and healthcare settings in Kono district.
    Serosurveys, vector characterization and social-cultural studies
    conducted by the Kenema Lassa Fever Research team in endemic
    areas across the country are ongoing.

    SITUATION INTERPRETATION

    Lassa fever is endemic in many West African countries. The current
    outbreaks in Sierra Leone, Nigeria, and Liberia highlight the need to
    step up Lassa fever prevention and control measures in West African
    countries, including improving sensitization to Lassa fever, community
    hygiene and routine universal precautions in healthcare settings.
    Strengthening cross-border surveillance and collaboration among
    West African countries are also paramount, given the high population
    movement between these countries.
