 Here I will explain you what is an illness and what two different types of illnesses there are. An illness could be defined as a unhealthy condition of the body or the mind. 

A virus is a micro-organism (It is a not living thing, neither a non living thing) that causes infections such as the common cold, bronchiolitis, tonsillitis, ear infections, influenza, mumps and chickenpox. There are hundreds of different viruses. Colds are very common in healthy children and on average, preschool children get at least six colds per year.

Not all diseases are contagious. A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens. Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases.

Cancer

Cancer is a disease in which cells divide out of control. Normally, the body has ways to prevent cells from dividing out of control. However, in the case of cancer, these ways fail. The rapidly dividing cells may form a mass of abnormal tissue called a tumor.
