Some of the challenges faced by developing countries with regard to health care are the increasing number of people that are aging and will be aging in the coming years. The World Health Organization consider that the number of old people, 65 years old and older, will increase from 249 million to 690 from the year 2000 to the year 2030. This will impact directly the health budget in developed countries in South America, Asia, and Africa because of the elderly demand so much medical attention as they are aging. The World Health Organization suggest these countries focus on preventing campaigns that inform people to take care of their health and supports a healthy living style to prevent chronic diseases. One example of this action could be the World Health Organization campaign of 2002 called "Innovative Care for Chronic Conditions," that focuses on prevention instead of resolution.
