    "description": "Most people are aware that some individuals are fatally allergic to bee and wasp stings, but the actual death toll is not well-known. Sting fatalities sit in a mid-range of public awareness: higher than sharks or lightning in general perception, but rarely a top-of-mind concern outside allergy communities. No comprehensive national survey isolates worry about venom anaphylaxis specifically.\n",

Compounded over 59 adult years: 1 − (1 − 0.000000218)^59 = 1 − 0.999987 = 0.0000129. Rounding to 0.000013, which is approximately 1 in 77,000. This is a population-average figure that blends people with known venom allergy (who face much higher risk without treatment), people with no known allergy who experience a first fatal reaction (~60% of deaths), and people with prescriptions for epinephrine autoinjectors (who face lower risk if they carry and use them promptly).\n",

This makes the risk difficult to eliminate through simple avoidance without systematic skin testing. Deaths from food-induced anaphylaxis (peanut, shellfish) are NOT included in this entry; this figure covers venom anaphylaxis only. Death is classified as due to \"hornet, wasp, or bee stings\" (ICD-10 code X23) on the death certificate, which may miss cases where the sting was a contributing but not primary listed cause. The 72/year figure likely slightly undercounts total venom- related deaths. Imported Africanized honey bees expand the exposure in southern states.\n",
