Didier Pittet

Didier Pittet is a really smart person who knows a lot about germs and how to stop them from making people sick. He is a doctor who works in a hospital and teaches other doctors how to keep their patients safe from germs.

Didier Pittet also came up with something called the "five moments of hand hygiene" which is a special way of washing your hands that helps kill germs. It's like a secret code that reminds doctors and nurses to clean their hands at the right times.

Thanks to Didier Pittet's ideas, hospitals are much cleaner and patients are less likely to get infections.
