Risk factors

  • Risk factors are often reported as percentages of those exposed out of those with information reported (e.g. 5% of cases had diabetes and 95% did not)  It is therefore just as important to record negative answers as it is to record positive answers.
  • Risk factor information is also often used for monitoring disease trends, source attribution studies or to determine potential sources of outbreaks.
  • It is important to record information for every risk factor field.
  • All questions about contacts/facilities in the risk factor field refer to the 14 days prior to onset or reporting.
  • This section uses option buttons, checkboxes and free text fields.
