Types of Disease

Some diseases are caused by pathogens, which include viruses, bacteria, fungi and protozoa.

Human Defence Systems

The human body has defence systems to prevent pathogens from causing harm. They include physical and chemical defences, and the immune system.

Treating Disease

Several methods can be used to prevent and treat disease, including aseptic environments and the development of different antibiotics.

Discovering and Developing New Drugs

To keep up with the high demand for new drugs to treat diseases, the production of pharmaceuticals is a fast-paced field of medicine.


Antibodies are developed by scientists for a variety of uses in medicine, from pregnancy tests to cancer treatment.


Vaccines give the immune system a chance to learn how to deal with pathogens, without the person becoming ill. They prevent the individual from contracting the illness in the future.

Plant Disease

Plants can become diseased from pathogens like viruses and fungi, be infested by pests like aphids, or become deficient in essential minerals.

Plant Defence Systems

Plant defence systems include a range of physical and chemical barriers, in addition to mechanical adaptations which physically defend the plant.
