It appears they revised the estimate: https://www.cdc.gov/flu/about/burden/2017-2018.htm https://www.cdc.gov/flu/about/burden/2017-2018.htm > Can you explain why the estimates on this page are different from previously published and reported estimates for 2017-2018? (For example, total flu-related deaths during 2017-2018 was previously estimated to be 79,000, but the current estimate is 61,000)? > The estimates on this page have been updated from an earlier report published in December 2018 based on more recently available information. There is a trade-off between timeliness and accuracy of the burden estimates. To provide timely burden estimates to the public, clinicians, and public health decision-makers, we use preliminary data that may lead to over- or under-estimates of the true burden. However, each season’s estimates will be finalized when data on testing practices and deaths for that season are available.
