An outbreak of poliomyelitis, Republic of Congo, 2010

Case st udy for the UK FETP / EPIET vaccinology module (3 hours)

Version 8– 8 May 2013 (Corrected after use in the module)

Objectives

  • Define the objectives of the investigation of an outbreak of poliomyelitis
  • Define the role of laboratory methods in supporting polio outbreak investigations
  • Formulate an operational case definition during an outbreak
  • Raise hypotheses about the determinants of an outbreak of vaccine preventable disease on the basis of:
    • Descriptive epidemiological data
    • An age-cohort analysis of the level of population immunity
  • Investigate case fatality ratio during an outbreak
  • Plan control measures for an outbreak of vaccine-preventable disease

Case study developed by ECDC (Yvan Hutin, Aftab Jasir, Helen Maguire and Pawel Stefanoff) in collaboration with the UK FETP (Sam Bracebridge), the EPIET Alumni Network (Arnaud Le Menach) and US CDC (Christopher Gregory and Minal Patel).

This case study is designed as a stand-alone and does not come with a facilitator’s guide. The answers to all the questions for each section are provided as an introduction to the following section. To run this case study, it should be distributed one section at a time (i.e., one sheet at the time if the case study is printed out double-sided). Once the epilogue has been read, it is proposed to go back to the first page to read the objectives again. This re-iterates the acquisitions and provides additional opportunity to clarify what may have been misunderstood or not fully acquired.
