disease

A disease is a health condition that has a specific set of symptoms and traits — such as malaria or heart disease.

Disease is not always about the human body being sick. Plants and animals are often the victims of disease. People also use the word disease in a more figurative sense to illustrate just how bad or damaging a negative influence can be — like the disease of greed among capitalists or the disease of plagiarism among college students.
