Good Quality Data: Driving response to outbreaks

The 2017 Cerebrospinal Meningitis outbreak has been ongoing for 20 weeks, affecting 211 Local Government Areas (LGAs) across 22 States and the Federal Capital Territory. Since onset, 13,420 suspected cases have been identified with 448 cases being laboratory confirmed. Over 50% (293) of the confirmed cases are due to Neisseria meningitides serotype C. The number of deaths recorded is 1,069 giving a case fatality rate (CFR) of 8.0%.

The data highlighted above has been the main drive in the response to this outbreak. The task of collecting, collating and analysing data is undoubtedly challenging, however, it is important that such effort put into the data collection process produces meaningful data. States have the sole responsibility of ensuring that the data generated from their wards/LGAs is a true representation of the outbreak situation.

In Nigeria, the recommended flow of surveillance data (routine and outbreak) starts from the community up to the National, with a feedback flow from the National down to the community. This forms an important component of the integrated disease surveillance and response (IDSR) strategy.

• IDSR 001C-Line list. This is a comprehensive summary of all suspected cases in an outbreak

• IDSR 002-Weekly reporting for 9 epidemic-prone diseases and public health events of international concern

• IDSR 003-Monthly reporting for 41 priority diseases

The data generated during this CSM outbreak has been the guiding tool for deploying support personnel to affected states, continuous requisition and utilization of vaccines provided by partners, supply of necessary testing kits, provision of antibiotics and coordination of other response activities. Poor data quality can affect the nature and impact of any response mounted during an outbreak. Updates to data already provided is encouraged as this further improves the quality of the data and further strengthens outbreak response activities.

The Nigeria Centre for Disease Control (NCDC) has been at the centre of coordinating activities in response to the CSM, alongside the National Primary Health Care Development Agency (NPHCDA) and other partner agencies. This response is made possible by the efforts of the States in providing good quality data. States are encouraged to work with their respective surveillance teams to ensure that data generated can be used as a tool to improve outbreak response and by extension, the entire surveillance system.
