Because the body adapts to fight an infection that it already has had so it takes a new one for you to get sick again
The difference between disease and illness is that a disease is something that can consume your whole body and it is often things like cancer, ALS and many other things. An illness is short lived, often like a cold.
There are as many as 50,000 new cases each year
If a disease is listed as a terminal disease it means that there is no cure for that disease at this time. New medical advances are happening every day in terminal diseases.
Every disease is an illness but not every illness is a disease (A disease is not a virus, parasite, etc but an illness could be)
