The Centers for Disease Control has published information about excess deaths since the pandemic and they are grim. According to this data, nearly 118,000 more people have died above the average deaths for the years pre-pandemic between 2015-2019.
The years 2020 and 2021 saw big spikes in excess deaths that continued into 2022. The data shows 7,680 more deaths this year alone in children and young adults but the trend does seem to be declining.
Likewise, in the UK, the amount of excess deaths there is still approximately 7% and seems to be declining.
There is no official reason for this but investigations are clearly needed.
