    "description": "Public perception of COVID-19 mortality risk is one of the rare cases where intuition broadly tracked reality, at least in aggregate. Survey work through 2020-2022 found that adults in most high-income countries overestimated their personal age-specific infection fatality rate by roughly an order of magnitude, but correctly identified COVID-19 as one of the leading causes of death in the acute-phase years. By 2024-2026 most readers file COVID-19 somewhere between \"serious respiratory illness\" and \"mostly an older-adult problem\", which is approximately where the population-level numbers put it. The perception gap on this fear is smaller than on plane crashes, sharks, or terrorism — and runs in both directions across subgroups.\n",

    "assumptions": "This is the hardest entry on the site to normalize, because the “lifetime” frame has to absorb a sharp 2020-2022 acute-pandemic surge followed by a much lower endemic rate from 2023 onwards. The headline 1 in 400 figure uses the Wang et al. (Lancet, 2022) global excess-mortality estimate of 18.2 million deaths (95% UI 17.1-19.6) in 2020-2021, adds roughly 3-5 million further excess deaths in 2022-2026 from the WHO confirmed-death series and IHME-style updates, and divides by a global adult population of ~6.0 billion (age 18+). That yields a cumulative 2020-2026 per-adult probability in the range of 0.0030-0.0037 unadjusted. Rounding down to 0.0025 reflects: (a) a substantial but not full share of excess mortality falling on adults rather than children (the age gradient is enormous — see the regional breakdown), (b) uncertainty in the excess-mortality attribution (some of the 18.2M excess is indirect — delayed care, lockdown-era non-COVID deaths — rather than COVID itself), and (c) the WHO confirmed figure of ~7.1 million as a lower bound anchor. Readers trying to estimate their forward risk should use the endemic annual rate (row 3 of regional_breakdown), not the cumulative figure, because almost all the mortality is already in the past. Scope is deliberately global-adult-lifetime rather than US-adult-lifetime because per-capita pandemic mortality varied by roughly an order of magnitude between countries and the global figure is the honest baseline.\n",

  "caveats": "The cumulative 2020-2026 figure collapses two very different epidemiological regimes into one number. Roughly 80% of all COVID-19 mortality since 2020 occurred in the acute-pandemic 2020-2022 window; the 2023-2026 endemic rate is about 50-100 times lower in absolute terms and continues to decline slowly. A reader trying to estimate their own *forward* COVID-19 mortality risk from 2026 onwards should use the endemic annual row in the regional_breakdown (~1.5 per 100,000 adults per year, concentrated almost entirely in adults aged 70+), not the cumulative figure. The headline 1 in 400 number is retrospective, not predictive. The underlying excess-mortality estimates (WHO ~14.8M, Wang et al. 18.2M, Economist model up to ~22M for 2020-2021) differ because of different modelling choices for countries with incomplete vital-registration data; the uncertainty band on this entry is wide (0.0012-0.005) to honestly reflect that methodological spread. The personal_factor_multipliers are illustrative order-of- magnitude figures from cohort studies and surveillance reports, not a calibrated individual risk calculator. This entry makes no claims about the efficacy, safety, or policy merits of any specific public health intervention — it reports the mortality numbers as published in peer-reviewed and WHO sources and leaves policy debates to other venues.\n",
