As at end June 2022, our official death toll for COVID-19 was 1,403 for Singapore residents. This accounts for around three-fifths of the excess deaths of 2,490, where the cause of death could be directly attributed to COVID-19. The remainder can be explained by patients who passed away from other illnesses within 90 days after being infected with COVID-19. In other words, COVID-19 aggravated existing illnesses, resulting in further mortalities. In a secondary analysis of persons without recent infection, no additional excess deaths were found.
