![]() ![]() The database may help scientists develop better mitigation strategies for this pandemic or future ones. The World Mortality Dataset provides a more accurate picture of the number of people who died because of the COVID-19 pandemic, and it is available online and updated daily. But they note that the actual number is likely much higher because data from more than 100 countries were not available to include in the database. Using their database, Karlinsky and Kobak estimate that, in those countries, there have been at least 1.4 times more deaths due to COVID-19 than reported – adding over 1 million extra deaths in total. Many countries reported their COVID-19 deaths accurately, but Karlinsky and Kobak argue that other countries, including Nicaragua, Russia, and Uzbekistan, underreported COVID-19 deaths. This is likely because social distancing measures reduced deaths from infections like influenza. ![]() Meanwhile, other countries like Australia and New Zealand, reported fewer deaths than normal. Some of the hardest hit countries, including Peru, Ecuador, Bolivia, and Mexico, experienced over 50% more deaths than expected during the pandemic. Karlinsky and Kobak used the database to compare the number of reported COVID-19 deaths reported to the excess deaths from all causes during the pandemic. It includes information on deaths from all causes from 103 countries. To provide a more accurate count of deaths caused by COVID-19, Karlinsky and Kobak built a database called the World Mortality Dataset. This tells them how many excess deaths occurred during the event. To get a better estimate of deaths from an event such as a pandemic, scientists often compare the total number of deaths in a country during the event to the expected number of deaths based on data from previous years. While some countries may have imperfect systems for counting deaths, others may have intentionally underreported them. ![]() eLife digestĬountries around the world reported 4.2 million deaths from SARS-CoV-2 (the virus that causes COVID-19) from the beginning of pandemic until the end of July 2021, but the actual number of deaths is likely higher. Our results highlight the importance of open and rapid all-cause mortality reporting for pandemic monitoring. Nicaragua, Russia, Uzbekistan), by up to two orders of magnitude (Tajikistan). Furthermore, we found that while many countries have been reporting the COVID-19 deaths very accurately, some countries have been substantially underreporting their COVID-19 deaths (e.g. Australia and New Zealand) mortality during the pandemic was below the usual level, presumably due to social distancing measures decreasing the non-COVID infectious mortality. At the same time, in several other countries (e.g. We found that in several worst-affected countries (Peru, Ecuador, Bolivia, Mexico) the excess mortality was above 50% of the expected annual mortality (Peru, Ecuador, Bolivia, Mexico) or above 400 excess deaths per 100,000 population (Peru, Bulgaria, North Macedonia, Serbia). We used this dataset to compute the excess mortality in each country during the COVID-19 pandemic. To fill this gap, we have collected weekly, monthly, or quarterly all-cause mortality data from 103 countries and territories, openly available as the regularly updated World Mortality Dataset. However, there has been no global, frequently updated repository of the all-cause mortality data across countries. Excess mortality, defined as the increase in all-cause mortality relative to the expected mortality, is widely considered as a more objective indicator of the COVID-19 death toll. Detailed COVID-19 vaccination coverage data and trends continue to be updated weekly and available on the COVID-19 Vaccination Coverage by Demographic Groups, COVID-19 Vaccine Coverage by Geography, and COVID-19 Vaccine Coverage Trends webpages (also linked below under “Chicago COVID-19 Data”).Īdditional data about COVID-19 activity in Chicago continues to be shared through our dashboard webpages and the Chicago Data Portal.Comparing the impact of the COVID-19 pandemic between countries or across time is difficult because the reported numbers of cases and deaths can be strongly affected by testing capacity and reporting policy. The “Vaccines” and “Vaccines by ZIP” tabs on the COVID-19 dashboard have been retired. ![]() You can find our current level, along with information about how it’s defined, on our COVID-19 Hospital Admission Levels webpage. ✶ĬDPH recommends that communities and individuals reference the hospital admission level for the greater Cook County area when making decisions about what preventive actions to take against COVID-19. ✶ Data and metrics will be refreshed as soon as these issues have been resolved. ✶ The COVID-19 dashboard's scheduled update has been delayed due to data processing issues. ![]()
