Weekly Epidemiological Report

November 2018 Week 47


Is the world ready for the next pandemic? Simulation exercise for National Public Health EOCs

Posted: 24-12-2018 08:45:56 AM

During the week in view, a simulation for a global pandemic response involving more than 40 countries took place from the 4th – 6th of December 2018. This was coordinated by the World Health Organization’s (WHO) Global Emergency Operations Centre (EOC) and the ‘EOC Network’, a global network of health emergency operations centres.

While the activity was the first global pandemic response training exercise, it was the second simulation exercise for the Nigeria Centre for Disease Control’s Incident Coordination Centre.

The scenario revolved around an ‘outbreak of influenza’ with pandemic potential on the fictional island nation of Mizzou, located off the coast of North America. There was no actual virus: it was a training exercise. The training exercise took place within the offices of national and international EOCs, without the deployment of people or goods and the exercise or disruption of public activities.

In Nigeria, participants included officers from the NCDC Incident Coordination Centre (ICC), the ‘one health’ Ministries (Federal Ministry of Health, Federal Ministry of Environment, and the Federal Ministry of Agriculture and Rural Development), WHO country office and the US Centers for Disease Control and Prevention (US CDC) Country Office. A representative from Public Health England was part of the exercise as the evaluator for Nigeria. It was an opportunity to be networked with other national EOCs that participated in the interactive scenario.

This exercise offered an opportunity for participating countries including Nigeria, to test their plans and capabilities in a realistic environment- in the event of a pandemic. Evaluators watched how the participating EOCs perform in real time, measuring performance against what was expected from existing procedures.

This experience identified gaps and opportunities that will ultimately help in the assessment and improvement of countries’ readiness to respond jointly and effectively to a global public health emergency.

The invitation to Nigeria to participate in this global exercise through the NCDC is a recognition of the critical role of NCDC in global health security.

In the reporting week ending on November 25, 2018:

o There were 146 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.
