disease without having to get smallpox first.

diseases, he had a more difficult job.
Bacteria is another name for germs that
cause disease.
bacteria – germs

When harmful microbes, or germs, enter the
body, they multiply and cause disease.
This is called infection.
Your body's defenses usually do a killer
job of squelching harmful microbes.
But sometimes germs multiply faster
than the body can handle and you get
sick. People come in contact with
germs in many ways, including:




Contaminated blood: Harmful microbes
can enter your body through your
bloodstream.
Infected food or water: Dangerous
microbes can enter through your mouth if
you drink untreated water or swallow
food that's uncooked or unwashed.
Disease-carrying creatures: Harmful
microbes can enter your body through
close contact with infected creatures.
Germy air: Dangerous microbes can
spread through the air and enter your nose
and mouth when you breathe.
