What is the difference between an infectious and a non-infectious disease?

I made a typo... Instead of "quicky", it should read "quickly". Sorry.

Update:

I've just been given a question during school and I need some help quicky. Here is the question.. any help would be appreciated :)

"Many diseases are caused by pathogens and are infectious. Many diseases are caused by other factors and are non-infectious. What is the difference between an infectious and a non-infectious disease? Use examples to help your answer."

    An infectious disease is caused by pathogens. A non-infectious disease is not caused by pathogens, and can be caused by other factors.

    Ex: Infectious: The flu, the common cold

    Non-infectious: skin cancer, scurvy

    Infectious - Diseases such as influenza, cold, etc., which are caused due to infectious

    agents . An infectious disease is classified as communicable because it can be

    transferred from an infected person to a healthy person.

    Non-infectious - Diseases such as high blood pressure, cancer, etc., which are

    caused by some internal causes such as excessive weight, genetic defects, etc.

    These are non communicable because it cannot be transmitted from a diseased

    person to a healthy person.
