An infectious disease is a clinically evident disease resulting from the presence of pathogenic microbial agents, including pathogenic viruses, pathogenic bacteria, fungi, protozoa, multicellular parasites, and aberrant proteins known as prions. These pathogens are able to cause disease in animals and/or plant
A non-infectious disease is a disease that may be caused by the environment (e.g skin cancer from radiation from the Sun) or from what we eat (e.g food poisoning) or malnutrition, lack of food (e.g Scurvy from lack of Vitamin C). Non-Infectious diseases can also be caused by genetic disorders.
