Finally, estimates of excess deaths attributed to COVID-19 might underestimate the actual number directly attributable to COVID-19, because deaths from other causes might represent misclassified COVID-19–related deaths or deaths indirectly caused by the pandemic. Specifically, deaths from circulatory diseases, Alzheimer disease and dementia, and respiratory diseases have increased in 2020 relative to past years (7), and it is unclear to what extent these represent misclassified COVID-19 deaths or deaths indirectly related to the pandemic (e.g., because of disruptions in health care access or utilization).
Deaths due to "lockdown" would be indirectly attributable to COVID-19 and therefore COVID-19-related deaths. Someone clearly can't read the article and is reading into it what he wants to see. Patients with circulatory diseases, Alzheimer disease and dementia, and respiratory diseases had these before Feb 1. They did not develop them after Feb 1.
