ELI5: Explain Like I'm 5

Hans Conrad Julius Reiter

Hans Conrad Julius Reiter was a person who lived a long time ago and was a doctor. He discovered something called "Reiter's Syndrome," which is when somebody has swelling in their joints, redness in their eyes, and a rash on their skin.

Sometimes, when people get sick, their body's immune system (which is like the body's defense team) gets confused and attacks the healthy parts of the body. This is called an autoimmune disease. Reiter's Syndrome is one of these diseases.

It's important to remember that people shouldn't be defined only by their discoveries or diseases. We are all unique and valuable, no matter what.
