Probable risk factors
———————
The event is driven by possible predisposing risk factors such as:
– attending and participating in funeral events — wake keeping, funeral, burial, and re-pass within the community of the deceased (Teah town);
– the risk of consuming the same food or drink that is probably contaminated; and
– environmental exposure.

Challenges
———-
– Establishing a full list of all attendees from outside and within Sinoe county who participated in the funeral events.
– Further laboratory testing is still ongoing to identify other potential causative agents of event.
– Inadequate disclosure of information related to the funeral event by family members and residents in Sinoe county.
– Lack of motivational package for community health volunteers (CHVs) involved with contact tracing & interpersonal communication.

Public health actions
———————

– the national level team is coordinating with the Montserrado CHT on follow up of people who participated at the funeral in Greenville;
– the health system remains resilient as people are still visiting the hospital normally to receive care; and
– in addition, all clinics remain opened with encouraging turn out while the implementation of African vaccines campaign ongoing.

Surveillance and contact tracing
– active case search ongoing in the affected and circumscribed communities in Sinoe county and follow of people who participated in the funeral in other counties;
– outbreak case definition developed to facilitate active case search;
– data from field investigations being analyzed to inform further laboratory tests;
– investigation and compilation of outbreak line list for all cases including contacts; and
– surveillance has been heightened at district and community levels including community engagement and sensitization.

Case management

– toxicological investigations: aliquots 11 specimens shipped to CDC-Atlanta for toxicological testing; efforts continuing to send samples to South Africa (WHO) and France (MSF) for further testing;

[Although the case numbers have not changed since the last ProMED-mail post (Undiagnosed disease – Liberia (03): (SI) fatal 20170429.5002799), this report provides additional details, including graphs and a map, about the occurrence with a description of the situation and anticipated plans and actions. The good news is that there have been no new cases, suggesting that the disease is not transmissible. It will be interesting to learn what the toxicological tests done at CDC might reveal. Those results are awaited with interest.
