A review suggests lockdowns may not be associated with large numbers of deaths in countries that avoided large COVID-19 epidemics. Lockdowns also did not lead to increased deaths from suicide, but mental health declined during the pandemic, making it challenging to separate lockdown impacts from COVID-19 itself.
A study analyzing age-at-death records of 33,715 Indigenous people in central California between 3050 BCE and 1870 CE found that Spanish settlers contributed to severe demographic collapse. The research suggests extreme social disruption caused by the presence of Europeans led to increased mortality rates among both males and females.
A recent study has found evidence of a large coronavirus epidemic that occurred in the East Asia region more than 20,000 years ago. The researchers used genetic data from the 1000 Genomes Project to discover changes in human genes that suggest ancestors of East Asian people experienced an epidemic similar to COVID-19.
