According to the World Bank report of 2016 (based on WHO's estimate), only 9.5% of the total deaths recorded in North Korea are attributed to communicable diseases and maternal, prenatal and nutrition conditions, a figure which is slightly lower than that of South Korea (10.1%) and one fifth of other low-income countries (50.1%) but higher than that of high income countries (6.7%). Only one out of ten leading causes of overall deaths in North Korea is attributed to communicable diseases (lower respiratory infection), a disease which is reported to have declined by six percent since 2007.
