Nigeria’s Growing Expertise in E-Health Knowledge and Skills (GEEKS)

Posted: 02-10-2018 19:22:32 PM

The seamless flow of information through an effective surveillance system is very important for the early detection and response to outbreaks. In addition, it enables feedback that helps to improve the efficiency and effectiveness of health programs, and improve health.

Given the need for a more competent informatics workforce in Nigeria, the Nigeria Centre for Disease Control (NCDC) in collaboration with the US Centers for Disease Control (US CDC) and Chinese Centre for Disease Control has begun the Growing Expertise in E-Health Knowledge and Skills (GEEKS) training in Abuja, Nigeria.

GEEKS is a three-tier approach to develop and maintain informatics capacity within a country’s health system through the development of a centre of excellence for informatics training. As a program hosted by Nigeria’s National Public Health Institute, GEEKS is a valuable, cross-cutting program to strengthen and improve health systems, population health, and global health security in Nigeria and Africa. The key target beneficiaries of the GEEKS Program include frontline public health workers, public health leaders, and informatics scientists and practitioners.

The first workshop in Nigeria was held in Abuja from 24th to 28th September, 2018. This workshop was the first tier of the GEEKS program with participants drawn from the Departments/programs of the Federal Ministry of Health, National Primary Healthcare Development Agency, Federal Ministry of Agriculture & Rural Development, State Ministries of Health (State Director of Public health, State Epidemiologist & State DSNOs), AIDS Prevention Initiative Nigeria (APIN), Institute of Human Virology, Nigeria (IHVN), Catholic Caritas Foundation of Nigeria (CCFN), Centre for Integrated Health Programme (CIHP), US-CDC, AFENET, Pro-Health, University of Maryland Baltimore, E-Health Nigeria and other stakeholders. Candidates who are successful at this level will proceed to the second tier.

The GEEKS program is an important strategy to strengthen surveillance and health information systems in Nigeria.
