Strong Partnerships to Prevent Epidemics in Nigeria

The Nigeria Centre for Disease Control (NCDC) has a strong network of partners that support the agency in the delivery of its mandate to protect the health of Nigerians. Since 2017, NCDC has been collaborating with Resolve to Save Lives (RTSL), an initiative of Vital Strategies, to prevent epidemics in Nigeria. On the 5th of August 2019, the collaboration between NCDC and RTSL was formally launched in Abuja, Nigeria.

Since the collaboration began, RTSL has provided support to NCDC across five main areas:

1. Implementation of the World Bank Regional Disease Surveillance System Enhancement project

2. Development and implementation of the National Action Plan for Health Security (NAPHS)

3. Epidemic preparedness through:

a. Capacity building of mid-level NCDC technical staff on project management for epidemic preparedness

b. Provision of emergency revolving fund

4. Improvement of coordination of the national yellow fever and measles networks of laboratories

5. Public awareness and domestic resource mobilisation through advocacy

The formal launch of the collaboration also provided an opportunity for the President/CEO of RTSL, Dr. Tom Frieden to visit the NCDC Headquarters, National Reference Laboratory and Maitama District Hospital.

The visit provided the two institutions with an opportunity to reflect, consolidate on and redefine the working relationship that has led to strong outputs. The visit also enabled the two institutions to assess the existing relationship and agree on priorities in the coming years.

We remain grateful to RTSL for the support that has led to improved capacities at NCDC, and are committed to strengthening national and global health security.
