Weekly Epidemiological Report

October 2018 Week 42


Building a National Emergency Medical Team (EMT) to improve preparedness and response

Posted: 06-11-2018 06:58:34 PM

In the reporting week, the NCDC in collaboration with World Health Organisation (WHO) and the Belgium First Aid Support Team (B-FAST) organised a three-day workshop on awareness of the Emergency Medical Team (EMT) initiative.

Globally, EMTs are formed to provide necessary support to countries that have experienced great disaster and outbreak situations in which local resources have been depleted/or cannot meet up with the demands of the emergency situations.

The participants included State Epidemiologists, academia, logisticians, military personnel, experts on emergency preparedness, members of staff from MDAs and development partners. The goal is that this multi-sectoral group can serve as the basis of representation for Nigeria’s EMT.

Presentations were made on the introduction to EMT, the core elements of an EMT, classification and standards of EMT and practical examples on how EMTs function and achieve success on the field. Group exercises were a core part of the workshop, with focus on various tasks.

A major output from this workshop was the development of an indigenous EMT plan with estimated timelines for achieving set tasks. The NCDC will continue to build and strengthen initiatives, that will enable adequate response to public health emergencies.


In the reporting week ending on October 21, 2018:

o There were 171 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.

o There were 954 suspected cases of Cholera reported from 38 LGAs in eight States (Adamawa – 101, Bauchi – 11, Borno – 328, Enugu – 8, Kaduna – 4, Katsina – 299, Yobe - 95 and Zamfara - 108). Of these, 25 were laboratory confirmed and eight deaths were recorded.

o There were 16 suspected cases of Lassa fever reported from nine LGAs in six States (Abia – 3, Ebonyi – 2, Kogi – 1, Ogun – 1, Ondo - 7 & Plateau - 2). Three were laboratory confirmed and two deaths were recorded.

o There were 11 suspected cases of Cerebrospinal Meningitis (CSM) reported from nine LGAs in eight States (Cross River – 3, Katsina – 1, Kebbi – 1, Ondo – 1, Osun – 1, Sokoto – 1, Taraba - 1 & Yobe – 2). Of these, none was laboratory confirmed and no death was recorded.

In the reporting week, all States sent in their report except Delta and Kano States. Timeliness of reporting remains 87% in both previous and current weeks (41 & 42) while completeness also remains 99% at same period.
