A year ago, the long-time anti-vaccine advocate and current US health secretary famously told The New York Times that a parasitic worm "
got into my brain and ate a portion of it and then died." The startling revelation is now frequently referenced whenever Kennedy says something outlandish, false, or offensive—which is often. For those who have followed his anti-vaccine advocacy, it's frightfully clear that, worm-infested or not, Kennedy's brain is marinated in wild conspiracy theories and dangerous misinformation.

The trouble is that now that Kennedy is the country's top health official, his warped ideas are contributing to the rise of a dystopian reality. Federal health agencies are spiraling into chaos, and critical public health services for Americans have been brutally slashed, dismantled, or knee-capped—from
infectious disease responses, the
lead poisoning team, and
Meals on Wheels to
maternal health programs and
anti-smoking initiatives, just to name a few. The health of the nation is at stake; the struggle to understand what goes on in Kennedy's head is vital.
While we may never have definitive answers on his cognitive situation, one thing is plain: Kennedy's thoughts and actions make a lot more sense when you realize he doesn't believe in a foundational scientific principle: germ theory.
Dueling theories
Germ theory is, of course, the 19th-century proven idea that microscopic germs—pathogenic viruses, bacteria, parasites, and fungi—cause disease. It supplanted the leading explanation of disease at the time,
the miasma theory, which suggests that diseases are caused by
miasma, that is, noxious mists and vapors, or simply bad air arising from decaying matter, such as corpses, sewage, or rotting vegetables. While the miasma theory was abandoned, it is
credited with spurring improvements in sanitation and hygiene—which, of course, improve health because they halt the spread of germs, the cause of diseases.
