The term "germ" encompasses an army of tiny terrors, including virus, fungi, parasite and bacteria. These "pathogens" all have the ability to spread from victim to victim called a host. Germs are so small you can see them only through a microscope. They look like spiky blobs, oozing spirals, hairy hot dogs, or other microscopic monsters.
How do we get sick from...
...Viruses?
Mot viruses are a frail little thing(unlike bacteria and fungi, viruses aren"t even alive)that can multiply itself only inside a living host(including animals, plants and even bacteria). There they spread, overwhelming and attacking hosts Immune System and causing all sorts of nasty symptoms. Cold, flus, chickenpox, immune disorders, and measles are caused by viruses. Among the worst is Ebola, which triggers bleeding and is fatal to more than half the people who catch it.
...Fungi?
These are microscopic molds, yeast and other plantlike pathogens that thrive in wet, warm places like armpits, our belly button and dank spaces between our toes. They feet on our sweat and dead tissues and produce stinky wastes that irritate our skin.
...Parasites?
This ghastly germ group include itty bitty insect larvaes, amoebas, and one celled organisms called protozoa that live in nasty food, damp soil, dirty water. Parasites depend on a living host for their survival. They sneak into our bodies in tainted water and food, causing all sorts of gastrointestinal gripes: diarrhea, vomiting, upset stomachs and worse Malaria-a common disease that causes chills, shaking and fever- is spread by mosquito bites. These life sucking relationship are the stuff for nightmares.
...Bacteria?
Unlike viruses, bacteria are living single celled organisms that can reproduce both outside and inside the body. Like all living things, they create waste-microscopic poops that can act as poison for the host. You can blame soar throats, ear infection, tooth tartar buildup on bacteria.
