# HEALTH INTEL: Antibiotic Resistance Timeline Penicillin discovery (1928) reduced bacterial infection mortality from ~30% to <5% within two decades, fundamentally extending human lifespan. Today, antibiotic-resistant infections affect 2.8 million Americans annually, causing 35,000+ deaths—a direct consequence of 75+ years of overuse in medicine and agriculture. The CDC projects antibiotic-resistant pathogens could cause 10 million deaths globally by 2050, exceeding cancer mortality rates, if resistance trajectories continue unchanged. This matters because modern surgery, chemotherapy, and organ transplants all depend on functional antibiotics; losing them forces medicine backward to pre-1940s infection mortality rates and surgical risk profiles.
