Summary: The study analyzed the life tables of 29 countries in 2020, finding that life expectancy at birth declined in most countries from 2019 to 2020, mainly due to increased mortality above age 60 and official COVID-19 deaths. The COVID-19 pandemic triggered significant mortality increases in 2020 on a scale not seen since World War II in Western Europe or the breakup of the Soviet Union in Eastern Europe.

Summary: The global spread of COVID-19 pandemic is influenced by the infectivity of the virus, human travel patterns, and mitigation measures. Spatial correlations of new active cases in different time periods were analyzed at the county level in the USA. The results showed that the epidemic did not progress uniformly and the length of correlation varied significantly. Travel between cities played a significant role in long-range spreading, particularly during the initial months of the epidemic. The presence of percolation transitions in November 2020 and January 2021 corresponded to the peak of the epidemic in the country.

Summary: This study examines the behavior of the case fatality rate (CFR) in a population with vaccinated and unvaccinated individuals. The results show that the CFR is influenced by both the effectiveness of vaccines and the detection of breakthrough infections. Therefore, a decline in the CFR does not necessarily indicate the effectiveness of vaccines in reducing deaths, and a constant CFR can still mean that vaccines are effective.

Summary: This study analyzed data from the Italian national database and found that age, sex, and infection timing had an impact on COVID-19 mortality. Specifically, older age was the most significant risk factor, male sex had a higher risk of death than female sex, and being infected during the first wave was associated with higher mortality risk.

Summary: The Demography of COVID-19 Deaths database aims to bridge the gap in poorly sourced and documented COVID-19 death counts. It provides detailed death counts and associated documentation for academics and stakeholders. The database allows for comparison of data quality and discrepancies across time and countries.

Summary: The outcomes of COVID-19 inpatients have evolved throughout the pandemic and have been influenced by changing demographics, virus variants, and vaccination. Vaccination and admission during the Omicron period are associated with lower inpatient mortality and healthcare resource utilization.

Summary: In 2021, there were diverging impacts of the COVID-19 pandemic on life expectancies in different regions, with vaccination rates negatively correlated with life expectancy deficits. Generally, countries in western Europe saw improvements in life expectancy, while those in eastern Europe and the United States experienced sustained deficits.

Summary: The study found that the mortality rate during the second wave of COVID-19 was related to the mortality rate during the first wave in the same provinces. Provinces with lower mortality rates in the first wave experienced higher mortality rates in the second wave, while provinces with higher mortality rates in the first wave had lower mortality rates in the second wave.

Summary: The study found that men had a higher relative risk of dying from COVID-19 compared to women in almost all age groups across ten European regions, but this sex difference decreased with age, with the smallest difference observed in the 80+ age group. Despite variations in data collection and time coverage, the overall pattern of sex differences in COVID-19 mortality in Europe was similar.

Summary: The study found that vaccination alone is insufficient to contain the outbreak. Even with an optimistic assumption that the vaccine can prevent 85% of infections, the reproduction number (R) is estimated to be 1.58 once all eligible adults have been offered both doses of the vaccine without non-pharmaceutical interventions (NPIs).

Summary: Sweden did not impose a lockdown during the first wave of COVID-19 infections, but a study shows that a 9-week lockdown could have significantly reduced infections and deaths, with the effects starting to show after 3-4 weeks. Despite some voluntary social restraint in Sweden, it was not as strong as under a lockdown scenario. Furthermore, it was found that a lockdown would not have caused much additional output loss.

Summary: The United States saw a significant decrease in life expectancy between 2018 and 2020, especially among Hispanic and non-Hispanic Black populations, widening the gap between the US and other high income nations. The disproportionate impact on racial and ethnic minority groups reflects longstanding policy choices and systemic racism.

Summary: Europe experienced excess mortality from February through June, 2020 due to the COVID-19 pandemic, with more COVID-19-associated deaths in males compared to females. However, a difference in excess mortality among females compared to among males may be a more general phenomenon and should be investigated in none-COVID-19 situations as well.

While there were no consistent temporal changes across all countries, several countries showed statistically significant patterns.

Summary: In Sweden, COVID-19 has led to significantly increased excess mortality in the age group above 60, with those above 80 being the most affected. Men had higher death rates compared to women in the age group up to 75. In older age groups, the excess mortality was similar for men and women, with rates reaching up to 1.5 times higher in Sweden and up to 3 times higher in Stockholm. Life expectancy at age 50 decreased by less than 1 year for Sweden and 1.5 years for Stockholm compared to 2019.
