In news that should surprise no one, Amazon’s study of Covid illness and death at its factories is appears to be intended primarily to obscure any meaningful data:

Amazon.com Inc.’s analysis of Covid-19 infection rates among its workers has several flaws and falls short of assessing whether the world’s biggest online retailer did a good job protecting its workforce through the pandemic, according to infectious disease experts who track pandemics.

Last week, Amazon said that almost 20,000 of its U.S. workers had tested positive for the coronavirus during a six-and-a-half-month period. Amazon, one of only a few companies to provide such data, said the infection rate in its ranks was lower than that of most states, a finding it cited as evidence that investments in sanitation, temperature checks and protective equipment were keeping workers safe.

But three experts interviewed by Bloomberg said the data was unhelpful because it failed to reveal whether the infection rate was improving or growing worse. One said Amazon’s comparison of its workforce to the general population is fundamentally flawed and reveals a lack of understanding of epidemiology. So while the announcement may have helped assuage some critics who say Amazon hasn’t done enough to protect workers toiling through a pandemic, it was essentially useless for employees trying to assess whether it’s safe to show up for work, they said.

Amazon doesn’t give a damn about the safety and security of its employees.  This report is an exercise in PR.
