Biological agents
Biological agents are living things, or products of living things, that can cause illness and disease in humans. Biological agents include viruses, bacteria and fungi, as well as parasitic worms and some plants.
They enter the body when they are inhaled, ingested or absorbed. Most biological agents are inhaled.
Once inside the body, these infectious agents can multiply quickly and may be passed from one person to another.
Some can survive outside the body for quite a long time if they have the right breeding ground, such as water and food. Others die quickly without the protection of the body.
