Global Worm Infection Scale in 1947
- In 1947, 2.2 billion worm infections existed among just under 2.2 billion people globally.
- Most infections could be prevented with proper sanitation, showing sanitation's critical role.
Discovery of Trichinella Spiralis
- A medical student, John Padgett, discovered worms in a human diaphragm in 1835 using a microscope.
- This discovery linked 'sandy diaphragm' to Trichinella spiralis worms, a key parasitic species.
Trichinella Spiralis Host Manipulation
