Using the EVD Investigation form

Contact the patient’s doctor to:

  • Confirm the onset date and symptoms of the illness
  • Confirm results of relevant pathology tests, or recommend that tests be done in accordance with local laboratory referral protocols
  • Find out if the case or relevant care-giver has been told what the diagnosis is before beginning the interview
  • Inform the doctor that public health staff will be contacting the patient/next of kin/carer
  • Review case management including infection control measures being used in caring for the case.

Interview the case or care-giver to:

  • Complete the exposure history and other sections of the EVD Investigation Form
  • Identify close contacts according to the contact definition.

Follow-up patient’s contacts to:

  • Assess risk of EVD transmission
  • Determine current symptoms, if any
  • Explain symptoms and need to immediately report any new symptoms
  • Explain to healthcare worker close contacts any need for work restrictions during the potential incubation period if there has been exposure
  • Provide an EVD Disease Factsheet and recommend any self-monitoring for relevant contacts.

Operational considerations for contact tracing

  • Define contact tracing team members and relevant roles and responsibilities
  • Define circumstances where contact tracing will be done by telephone or in person
  • Consider need for dedicated call centre and scripts in response to a notified case
  • Formalise the process for the management of contact surveillance data.

Training for contact tracing team

  • EVD transmission
  • Rationale for contact tracing
  • Training in use of contact interview form and explanation of fact sheets, including if/how jurisdictions will recommend restrictions for contacts of confirmed cases
  • Infection prevention and control measures for contact tracers, including use of PPE, and instructions for use of thermometers if face to face interviews or assessments are conducted

Resources

  • Contact listing sheets, case and contact interview forms
  • Temperature logging forms for contacts
  • Information/fact sheets for contacts
  • Consideration of thermometers supplied to contacts, or advice on which thermometers to use
  • If face to face contact tracing or assessments are conducted, consider need for alcohol-hand rub, supply of PPE– disposable gloves, P2/N95 masks, gowns, goggles; and guidelines on when to use / put on PPE; general guidance for conduct during home visits such as no physical contact with people or objects at location, maintain > 1 metre distance from individuals, don’t enter the residence)

Policy for health monitoring of contact tracers

  • Consider the need for temperature monitoring in the event that face to face contact tracing is required and symptomatic contacts are encountered.

Reporting

  • Notify central jurisdictional communicable disease control agency and Chief Human Quarantine Officer.
  • Central communicable disease control agency to notify Commonwealth Department of Health, Office of Health Protection.
  • Consider need for media release and designate a media spokesperson.
