Blending Science and Communication- The Art of Scientific Writing

Nearly every week, a Rapid Response Team is deployed from the Nigeria Centre for Disease Control (NCDC) to respond to an outbreak. In addition to this, we are constantly reviewing and adapting best practice in infectious disease control through the development of guidelines, as well as strengthening our disease preparedness, surveillance and response strategy. In recognition of the need to share our experience with other public health institutes and contribute to science, we have identified scientific communication as one of the major priorities at NCDC in 2019.

With support from the International Association of Public Health Institutes (IANPHI) and United States Centre for Disease Control (US CDC), NCDC held a two-week training on scientific communication and writing. The training was a two-week blended programme aimed at building the capacity of early career and mid-level staff in critical areas of research, data analysis, writing and data visualisation.

Over the last two years, members of the NCDC Team have published articles in peer-reviewed journals, including the Lancet Infectious Disease Journal, Eurosurveillance, CDC Emerging Infectious Disease journal, BMJ Global Health, International Journal of Infectious Disease and several others. These can be found on our website (see link)

There is no doubt that developing and sharing experience is a critical aspect of science and public health. The NCDC remains committed to developing timely and evidence-based information as contribution to global health security.
