How to report a COVID-19 related deaths? 

Any death where COVID-19  is a contributing factor as the cause of death, should be reported in COVID-19 cases where there is no clear alternative cause of death (e.g., trauma, drug toxicity, other natural death process, at a time that the person was COVID-19 test positive but did not have a clinically compatible illness), and the death occurred under one of the following circumstances:

  • The case was still symptomatic or infected at the time of death.
  • The case was experiencing residual effects or complications of infection that persisted.
  • The case is a child that was experiencing multi-system inflammatory syndrome (MIS-C) which can occur after resolution of initial COVID-19 signs and symptom.
