"What are the most important epidemiological and demographic issues that face health systems, and what are the implications of those issues for healthcare costs?"

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

The most important epidemiological and demographic issues that face health systems and the implications of those issues for healthcare costs are the following.

1.- Aging populations. 2.- Noncommunicable diseases. 3.- The cost of health services in the elderly. 4.- Different ethnicities or races that are prone to different diseases.

The health costs are getting higher and the quality of service is not increasing to cover the many necessities of the American people across the country.

The new generation of doctors and medical administrative staff are not as well prepared to offer the quality of services that are demanding in today's changing environment. There is a lack of resources or maybe planning, that contemplates the growing number of elderly people and poor people that need continuing medical attention in different parts of the country. Necessities are increasing, people in need are growing, and the health system is facing severe problems to offer proper solutions, as has been shown during this pandemic.
