    Answer:
A disease occurs when cells or molecules in your body stop working properly, causing symptoms of illness. Many things can cause a disease, including altered genes, chemicals, aging, and infections. An infection occurs when a microbe-such as a virus, bacterium, fungus, or parasite-enters your body and begins to reproduce. The invading microbe can directly damage cells, or the immune system can cause symptoms, such as fever, as it tries to rid your body of the invader. Some infections do not cause disease because the microbe is quickly killed or it remains dormant.
