The first thing to be said in response to this is that there definitely is something special about SARS-CoV-2. Namely, that it is the only known SARS-like virus with a furin cleavage site - likely a feature it was given in a lab - which makes it unusually infectious. This essentially makes it like SARS-1 but with aerosol transmission, and so far more transmissible.
A second thing to underline is that no one has yet shown any convincing relationship between policy interventions and deaths. Studies based on real-world data rather than modelling show that restrictions made little or no difference to outcomes. Here are five examples:
- "Full lockdowns and wide-spread COVID-19 testing were not associated with reductions in the number of critical cases or overall mortality." "A country level analysis measuring the impact of government actions, country preparedness and socioeconomic factors on COVID-19 mortality and related health outcomes" by Rabail Chaudhry, George Dranitsaris, Talha Mubashir, Justyna Bartoszko, Sheila Riazi. EClinicalMedicine (Lancet) 25 (2020) 100464, July 21st, 2020.
- "We find that shelter-in-place orders had no detectable health benefits, only modest effects on behaviour, and small but adverse effects on the economy." "Evaluating the effects of shelter-in-place policies during the COVID-19 pandemic" by Christopher R. Berry, Anthony Fowler, Tamara Glazer, Samantha Handel-Meyer, and Alec MacMillen, Proceedings of the National Academy of Science of the USA, April 13th, 2021.
- "Stringency of the measures settled to fight pandemia, including lockdown, did not appear to be linked with death rate." "Covid-19 Mortality: A Matter of Vulnerability Among Nations Facing Limited Margins of Adaptation" by Quentin De Larochelambert, Andy Marc, Juliana Antero, Eric Le Bourg, and Jean-François Toussaint. Frontiers in Public Health, November 19th, 2020.
- "Comparing weekly mortality in 24 European countries, the findings in this paper suggest that more severe lockdown policies have not been associated with lower mortality. In other words, the lockdowns have not worked as intended." "Did Lockdown Work? An Economist's Cross-Country Comparison" by Christian Bjørnskov. CESifo Economic Studies March 29th, 2021.
- "While small benefits cannot be excluded, we do not find significant benefits on case growth of more restrictive NPIs." "Assessing Mandatory Stay‐at‐Home and Business Closure Effects on the Spread of COVID‐19" by Eran Bendavid, Christopher Oh, Jay Bhattacharya, John P.A. Ioannidis. European Journal of Clinical Investigation, January 5th, 2021.
Comment: Whie at the beginning this may have been true, at this point the continued excess mortality seems to be less due to the virus more likely due to other causes.
