    "description": "In wealthy countries, tuberculosis is widely treated as a 19th-century disease — the illness of Victorian novels, sanatoriums, and Keats, not of 2026. Most Likelier readers in the US, Western Europe, Japan, or Australia would guess their personal odds of dying from TB at essentially zero, and for them that guess is roughly correct. What the same readers almost universally get wrong is the global picture: TB has been the world’s leading infectious-disease killer for most of the past decade, it regained that title from COVID-19 in 2023, and it kills roughly twice as many people every year as HIV/AIDS. We have not found a cross-national survey that isolates “fear of dying from TB” as a clean question, so the perceived side here is editorial intuition, not polled data.\n",

  "caveats": "The ~1 in 110 figure is a global-average scale marker and is almost useless as a personal estimate. Tuberculosis mortality is overwhelmingly concentrated in eight countries (India, Indonesia, China, Philippines, Pakistan, Nigeria, Bangladesh, and South Africa) which together account for roughly two thirds of global cases, and within those countries risk is further concentrated in people living with HIV, in malnourished populations, in prisons and crowded institutional settings, and in household contacts of active cases. For residents of the US, Western Europe, Japan, and Australia without any of those risk factors, annual risk is ~1 in a million or lower — a gap of roughly five orders of magnitude versus the global headline. The global number has also been moving: TB deaths rose during 2020–2022 as COVID-19 disrupted TB programs, then began declining again. The WHO Global TB Report 2025 (reference year 2024) put deaths at ~1.23 million and ill people at 10.7 million — both modest declines from 2023 — while a record 8.3 million people were newly diagnosed and reported, the highest case count ever recorded (a detection/notification record, not a sign the epidemic grew). Drug-resistant TB remains a persistent gap: of the ~390,000 people who developed rifampicin-resistant TB in 2024, only about 42% — roughly 2 in 5 — accessed treatment (WHO Global TB Report 2025).\n",
