Many of the developing countries face the dual or double burden of diseases. While at one end they struggle to fulfill adequate nutritional requirements of their citizens, they also have to contend with chronic disease that have to do with lifestyle. Hunger and malnutrition (including iodine deficiency, vitamin deficiency, etc.) is a cause of great concern for any country, as the economically weak strata of society suffer stunted mental and physical development, disability and thereby affects national growth. Changing lifestyles and diets, especially of the middle class, is giving rise to chronic diseases. Obesity is one such example and leads to concomitant health effects such as heart disease, hypertension, diabetes, etc.
In the past these two conditions, malnutrition and chronic disease, were treated as separate entities, they are now thought of as two sides of the same coin and hence the term "dual burden" of diseases.
Hope this helps.
Many developing countries will face the dual, or double burden of diseases. The two categories this phrase refers to are non-communicable diseases and infectious diseases. Examples of non-communicable diseases are diabetes, depression, and cancer. According to the World Health Organization (WHO), "infectious diseases are caused by pathogenic microorganisms." The burden is that now in addition to infectious diseases, non-communicable diseases are spreading globally. By 2020, it's expected that as much as 70 percent of deaths in developing countries will be from a non-communicable disease.
