A communicable disease is contagious. It can sometimes be
an airborne disease. It can be spread through a community. If a
person who has a communicable disease sneezes or coughs, and you breathe in what
they breathed out, you can be exposed to what they have. You can also get
communicable diseases just by interacting with someone who has the virus or
bacterium.
There are still many more ways to get a
communicable disease. For example, if I were to touch something that you
touched, and you have pink eye, and then if I were to rub my eye, I would then
be exposed to pink eye.
A few other examples of the common
communicable diseases are the flu, chicken pox, West-Nile encephalitis, the
cold, pneumonia, small pox, rabies, and SARS.
And now you know that communicable diseases
are easily spread through communities.
