What Are Germs?
The term "germs" refers to the microscopic bacteria, viruses, fungi, and protozoa that can cause disease.
Washing hands well and often is the best way to prevent germs from leading to infections and sickness.
What Are the Types of Germs?
Bacteria
Bacteria (bak-TEER-ee-uh) are tiny, single-celled organisms that get nutrients from their environments. In some cases, that environment is your child or some other living being.
Some bacteria are good for our bodies — they help keep the digestive system in working order and keep harmful bacteria from moving in. Some bacteria are used to make medicines and vaccines.
But bacteria can cause trouble too, as with cavities, urinary tract infections, ear infections, or strep throat. Antibiotics are used to treat bacterial infections.
