Weekly Epidemiological Report

February 2019 Week 7


NCDC Holds its Technical Working Group Meeting for Ebola preparedness and Response:

Posted: 05-03-2019 08:13:50 AM

Ebola Virus Disease (EVD) is a viral haemorrhagic fever which continues to pose major public health threats to the livelihood of the global community. The 2014-2016 EVD outbreak in West Africa, the largest in the global history was associated with over 27000 cases and 12000 deaths causing social, economic and political disruption. However, the Federal Ministry of Health through the Nigeria Centre for Disease Control (NCDC) was able to detect the disease early enough, mounted effective response, prevented further escalation and eventually nipped it in the bud.

As at February 26 2019, 872 cases (807 confirmed and 65 probable), with 548 deaths were reported in North Kivu & Ituri provinces, in Democratic Republic of Congo.

In view of the foregoing, and in addition to the trans-border potential of EVD, NCDC has continuously strengthened its Emergency Preparedness and Response (EPR) activities including intensive border surveillance especially among States that share borders with other neighbouring countries. Apart from ensuring early detection of any possible imported case (s), an effective surveillance system also provides a window of opportunity for timely response to detected cases.

Further, NCDC also held its EVD Technical Working Group (TWG) meeting at the NCDC Headquarters, Abuja on the 28th of February to discuss ongoing preparedness efforts and to ultimately develop a contingency plan for EVD. The aim of the meeting was to review our preparedness efforts, join forces and develop a contingency plan for EVD.

The major outcome of the meeting was the establishment of a structure with subsequent allocation of TWG members to different pillars for the development of the plan. These pillars include Epidemiology / Surveillance; Point of Entry; Data management; Case Management / Psycho-social; Risk / Corporate Communication; Logistics; Laboratory; and Coordination.

While NCDC continues to fulfil its mandate of protecting the health of Nigeria through its pro-activeness in early detection and response to epidemics and other public threats, it is hoped that the contingency plan will continue to provide basis for our future emergency preparedness and response activities.


In the reporting week ending February 17, 2019:

o There were 113 new cases of Acute Flaccid Paralysis (AFP) reported. None was confirmed as polio. The last reported case of polio in Nigeria was in August 2016. Active case search for AFP is being intensified with the goal to eliminate polio in Nigeria
