Noncommunicable – or chronic – diseases are diseases of long duration and generally slow progression. The four main types of noncommunicable diseases are cardiovascular diseases (like heart attacks and stroke), cancer, chronic respiratory diseases (such as chronic obstructed pulmonary disease and asthma) and diabetes.
Noncommunicable diseases, or NCDs, are by far the leading cause of death in the world, representing 63% of all annual deaths. Noncommunicable diseases (NCDs) kill more than 36 million people each year. Some 80% of all NCD deaths occur in low- and middle-income countries.
