  • Following critical health care IPC strategies and measures are required to prevent or limit SARS-CoV-2 transmission in health facilities, including having the following in place: an IPC programme or at least a dedicated and trained IPC focal point, engineering and environmental controls,
  • administrative controls, standard and transmission basedprecautions, screening and triage for early identification of cases and source control, robust surveillance and vaccination of health workers.
  • Optimal compliance with appropriate use of personal protective equipment and hand hygiene by health workers is associated with decreased risk of SARS-CoV2 transmission.
  • Infection prevention and control (IPC) training of health workers is associated with decreased risk of occupational acquisition of COVID-19. a Health facility (including primary, secondary, tertiary care levels, outpatient care and long-term care facilities) b Individuals accessing the healthcare facilities not to directly seek healthcare service, but to physically be present with a patient.

  • Universal masking by all patients, staff, caregivers and visitors within a health facility should be implemented in health facilities in areas where there is known or suspected community or cluster transmission of SARSCoV-2. Targeted continuous masking should be implemented in clinical areas of health facilities in areas with known or suspected sporadic transmission.
  • IPC precautions should be applied for COVID-19 vaccine administration. Mask use by vaccinators and recipients of the vaccine should be according to local or national guidance.
