Why Global Citizens Should Care

Noncommunicable diseases (NCDs), such as cancers and diabetes, are now the leading cause of death in the world, according to the World Health Organizations (WHO) 2019 Global Health Estimates report published Wednesday.

The top10 diseases accounted for 55% of the 55.4 million deaths worldwide that were reported in 2019.

It is important to understand which diseases people die from to measure how people live and to ensure that health care systems areprepared to respond to patients needs, according to the WHO.

The WHOdefines NCDs as chronic diseases that are usually the result of genetic, physiological, environmental, and behavioral factors. In comparison, communicable diseases are transmitted between people, such as HIV/AIDS, tuberculosis, malaria, and tropical diseases.

At the global level, 7 of the 10 leading causes of death were NCDs in 2019. This is a dramatic rise from 2000, when only 4 of the top 10 diseases were classified as noncommunicable.

These new estimates are another reminder that we need to rapidly step up prevention, diagnosis,and treatment of noncommunicable diseases, WHO Director-GeneralDr. Tedros AdhanomGhebreyesussaid.

In 2019, heart disease remained the number one killer globally and accounted for 16% of total diseases around the world, according to the report.

Heart disease has been the leading cause of death globally for the last 20 years. The number of people who died from the disease in 2019 rose to almost 9 million.
