Answer 1

Hint:Disease refers to an abnormal condition that affects a living organism. It affects the normal structural or functional state of an organism. The disease is associated with certain signs and symptoms.

Complete answer:
Disease is an abnormal condition of the structural or functional state of an organism. The disease is
generally associated with certain signs and symptoms. A diseased individual commonly exhibits certain signs or symptoms, that suggest an indication of an abnormal state of that particular individual.

The visual changes in human beings due to abnormal functioning of organs or the dysfunctioning of one or more systems of the body give certain abnormal signs of the disease, which can be referred to as symptoms. The symptoms give an indication of the presence of a particular disease.

Symptoms can be defined as evidence of disease. Symptoms are of three types:
1) Remitting symptoms: When symptoms improve or resolve completely. For example, symptoms of the common cold may occur for several days and then resolve without treatment.
2) Chronic symptoms: Long-lasting or recurrent symptoms. It is often seen in diseases such as diabetes, asthma, and cancer.
3) Relapsing symptoms: These are the symptoms that have occurred in the past, resolved, and then returned. For example, symptoms of depression may not occur for years but may then return.

Two examples of symptoms are:
(i) Lesions on the skin are the symptoms of chickenpox.
(ii)Cough is a symptom of lung infection.

Note:It is to be noted that the sign is any objective evidence of a disease that can be observed by others such as a physician, nurse, or medical device during the examination of a patient.
