EVENT DESCRIPTION
On 4 February 2020, the Ministry of Health and Social Affairs in
Mali informed WHO of an outbreak of Crimean-Congo haemorrhagic
fever (CCHF) in Mopti District, located in the south-eastern part of
the country, at the border with Burkina Faso. The event was initially
reported to the Mopti health authority on 1 February 2020 when a
cluster of community deaths occurred and case-patients manifesting
haemorrhagic symptoms presented to local health facilities in
Korientz? health area. The index case in this event was a 39-year old
male shepherd from K?ra village who fell ill on 5 January 2020
with symptoms of epistaxis, haematemesis and general fatigue. The
case-patient received unspecified treatment in the community and
later died on 11 January 2020. On 15 January 2020, an aunt of the
index case (who cared for him) developed a similar illness and died
on 23 January 2020 in the community. Between 27 and 30 January
2020, three other family members fell ill with a similar illness and
died in the community. During the same period, nine case-patients
from the same community presented to the local health facilities
with haemorrhagic symptoms. Blood specimens collected from the
nine case-patients in admission were analysed at the National Public
Health Institute. Of the nine specimens, three tested positive for
CCHF virus infection, thus confirming the outbreak.
Between 5 January and 2 February 2020, a total of 14 suspected
CCHF cases, including seven deaths (case fatality ratio 50%) have
been reported. Of the seven deaths, five occurred in the community
and two occurred in a health facility. A total of 13 out the 14 suspected
cases are females. Five case-patients remain admitted in healthcare
facilities and are receiving treatment. Further investigation into this
event is ongoing and updates will be provided as new information
becomes available.
PUBLIC HEALTH ACTIONS
The district rapid response team conducted initial outbreak
investigation in the affected community and commenced
implementing response activities. Preparations are ongoing to
deploy the national rapid response team to carry out detailed
epidemiological investigation and support local response.
Disease surveillance is being strengthened in the affected region
to facilitate early detection of suspected cases in the community
and health facilities.
Healthcare workers are being oriented to improve their capacity
to respond to the outbreak effectively.
Risk communication and community mobilization activities are
ongoing using various approaches and channels.
SITUATION INTERPRETATION
The Ministry of Health in Mali has confirmed an outbreak of CCHF in Mopti
district, an event coming after over a decade of no reported outbreaks of
the disease in the country. However, recent sero-prevalence studies in
both human and other animals demonstrated that the virus is circulating
in the country. The affected region is plagued with intense insecurity
resulting in a complex humanitarian crisis. Provision of and access
to healthcare services is severely compromised, with the region beng
categorised as hard-to-reach due to the deteriorating insecurity. As a
result, several of the initial cases died in the community at the beginning
of the outbreak. Because of these factors,
the current outbreak has the
potential to escalate further. The national authorities and partners need
to conduct detained epidemiologic investigation to established the
extent of this event and institute proportionate public health actions to
bring it to a close.
