Types of Communicable Disease
Pathogens are micro-organisms that enter the body and cause diseases. These cause communicable diseases - these can be spread. Both plants and animals can be infected by pathogens.
These are very small which can reproduce rapidly. They can make you very ill by producing toxins that damage the cells and tissues.
Viruses are not cells. They're tiny. They live inside the cells as they reproduce until there are too many of them which then causes the cell to burst, spreading the virus around the body.
These are Eukaryotes. Some carry parasites and can be transferred by a vector.
Single-celled. Spread by spores.
