There 2 main types of germs, Microorganisms and Viruses.
Viruses
are a microscopic particles that cannot reproduce on their own. To reproduce they
must infect another the cell of a biological organism. Viruses are made up of capsids.
A capsid is genetic material surrounded by a protective protein coating. Different
types of viruses can infect a wide variety of organisms. They may infect animals,
fungi, plants yeasts and bacteria. Virology is the study of viruses and "virus"
is Latin for poison. Notable viral disease includes HIV/AIDS, influenza/FLU and
various other fevers.
Microorganisms, also known as microbes is any organism that that is microscopic.
We are mostly concerned with pathogenic microbes that can invade other organisms
causing disease. The most alarming that we want to know about is bacteria. Bacteria
are the cause of diseases such as tuberculosis, plague, anthrax, malaria and sleeping
sickness.
There are ways of managing your exposure risk to viruses and bacteria all while
leading the exact same normal life that you are. Knowing that a door knob carries
more bacteria and viruses than a toilet seat is the biggest lesson that you can
learn. Also the use of ant-bacterial items that are in constant contact with hands
(such as keyboards and computer mice) are simple measures that will greatly reduce
your risk. Check out the "Truth about Soap" for a major piece of information that
nearly all people over look.
