This article summarises the relevant WHO guidance for educational purposes for healthcare professionals.

How can professionals prevent the spread of COVID-19?

  • Early identification and isolation of suspected COVID-19 cases

  • Using precautions whilst caring for any patient

  • Using additional precautions whilst caring for suspected COVID-19 cases

Isolating suspected COVID-19 patients:

Healthcare professionals should aim to identify possible COVID-19 cases early by maintaining a low threshold to consider COVID-19 and by implementing early triage stations and questionnaires.

Using standard precautions during care of all patients:

Patients with suspected COVID-19 should be given face masks for public waiting areas, respiratory hygiene and rigorous hand hygiene should be applied. Healthcare professionals should use the WHO 5 moments for hand hygiene.
