Tuberculosis has recently regained it long-held distinction as the world’s deadliest infectious disease. But it’s not just the deadliest disease infectious disease right now, killing over 1,500,000 people each year. It’s also the deadliest infectious disease ever, killing over a billion people just in the last 200 years.
TB is older even than our species. It infected hominids like homo erectus over a million years ago.
Only in the last seventy years has the disease been largely curable. If everyone with TB received appropriate treatment and support, and if their loved ones received preventative therapy, TB deaths could decline by over 50% in the next decade.
For me, this is a cause of both hope and despair. Hope, because so many people work together to make breakthroughs in treatment, or to build and maintain the systems that allow treatment to be distributed, or to advocate for expanded treatment access. But also despair because we know almost all of these deaths are unnecessary and directly result from a human world that fails to acknowledge the truth that all humans lives are equally valuable.
