“Excess deaths” is the best metric for tracking the pandemic – The BMJ

The pandemic’s true death toll: millions more than official counts.

We can be confident there have been far more than 5 million global Covid deaths – “Estimating ‘excess’ fatalities, a more robust analysis method, puts the pandemic’s grim toll between 10m and 19m people”.

Global Covid-19 deaths surpass five million.

Effects of the Covid-19 pandemic on life expectancy and premature mortality in 2020 – this time series analysis showed there were more than 28 million excess years of life lost in 2020 in 31 countries.

Under-reporting of deaths limits our understanding of true burden of covid-19.

Study shows COVID-19 has caused the biggest decrease in life expectancy since World War II.

Report: Three new estimates of India’s all-cause excess mortality during the COVID-19 Pandemic – pandemic death toll estimated to be between 3.4 million and 4.9 million excess deaths.

COVID-19 has caused 6.9 million deaths globally, more than double what official reports show

If you want to track the pandemic and compare performance, then 'excess deaths' is the best metric. @_Nazrul_Islam explains.

For example, UK excess deaths have been running at higher than predicted levels since the middle of 2021.@bmj_latest https://t.co/fiMpk4tiIj pic.twitter.com/SKIvStmxm8

The pandemic has far reaching effects—direct and indirect—beyond illnesses and deaths caused by SARS-CoV-2. Using the metric of excess deaths can help us to track this, argues @_Nazrul_Islam https://t.co/PzxgPbkqk0
