- Chronic diseases
Most chronic diseases in Europe are non-communicable diseases, which are diseases that are non-infectious and non-transmittable among people. They are of long duration and generally of slow progression. The four main types of non-communicable diseases are cardiovascular diseases (e.g. heart attacks), cancers, chronic respiratory diseases (e.g. asthma) and diabetes. (Source)
