How Does Hand Sanitizer Work?

In this week's Ask A DOer, Dr. Richard explores David's question, “How does hand sanitizer work?” Diving into the microenvironment of germs Dr. Richard explains what germs are, how hand sanitizer helps protect us from germs, and most importantly whether you need to wash your hands even if you use hand sanitizer. Buckle up as we journey to the very small world of germs! 

Terms You've Learned: 

Germs (n.) - A germ is a tiny organism that can cause disease. Several different kinds of organisms can be germs, including bacteria, protozoans, and fungi. Viruses--which might or might not be considered "living" organisms — can also be germs.

Microscopic (adj.) - Very small and invisible to the unaided eye — you need a microscope to see something that's microscopic.

Cells (n.) - The smallest unit of life. Some organisms are made up of a single cell, like bacteria, while others are made up of many, like you!
