AbstractReports of excess mortality during the COVID-19 pandemic in Argentina have been partial and fragmented so far. This study aimed to quantify excess deaths and explore their demographic, temporal, and geographic distribution during the period 2020-2022. Using data from 1 192 963 death records from vital statistics and population projections, expected mortality was estimated using regression models. Excess death was calculated as the difference between observed and expected mortality. An excess of 160 676 deaths (95% CI 146 861 to 174 491) was estimated, representing a rate of 116.9 (95% CI 115.5 to 118.3) additional deaths per 100 000 personyears. Significant heterogeneity was found among the different argentine provinces. The results indicate an uneven impact of the pandemic, with higher excess mortality rates in some regions and more vulnerable age groups. These patterns suggest the need for differentiated strategies of healthcare response and support to the most vulnerable populations in scenarios of new epidemics.
