Communicable Disease

Non-communicable diseases (NCDs) are illnesses that cannot be spread from one person to another directly. Parkinson's disease, autoimmune disorders, strokes, the majority of heart and cancer illnesses, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, cataracts, and other conditions are examples of NCDs. NCDs can be acute or chronic. Although some non-communicable infectious diseases, such parasitic illnesses, in which the parasite's life cycle does not directly involve host-to-host transmission, exist, the majority of diseases are not contagious. The main cause of mortality worldwide is NCDs. They were responsible for 38 million fatalities in 2012, an increase from 60% in 2000. Half were female and under the age of 70. The likelihood of some NCDs is increased by risk factors such as a person's background, lifestyle, and environment.
