Hi mate:
Viruses, bacteria and parasites are living organisms that are found all around us. They exist in water and soil, on the surfaces of foods that we eat and on surfaces that we touch and etc...Some bacteria live in our bodies and do not cause problems. Other kinds of bacteria can make us quite ill if they invade our bodies.Bacteria and viruses can live outside of the human body sometimes for many hours or days. Parasites, however, require a living host in order to survive.
I hope this would help you..
Thanks for asking and keep asking more....
