A student is classifying countries by their stage of epidemiological transition. Country A has the following characteristics: the average per capita income is approximately $14,000, almost $6,000 more than it was 10 years ago; there are above average numbers of deaths from the flu and measles each year than in other countries; however, because these deaths have been decreasing in recent years, there has been a dramatic increase in life expectancy from 44 to 56 in the last 15 years. In addition, heart disease is now the primary cause of death for individuals in the middle and upper classes. Which transition stage best fits? Why?
A. pre-transition: There are many deaths from acute diseases, and although the life expectancy is increasing, it is still low; this suggests that Country A has not experienced the epidemiological transition. B. in transition: Although there are many more deaths from acute diseases than in other nations, those are decreasing, whereas chronic conditions are increasing; these large changes suggest that Country A is currently experiencing the epidemiological transition. C. post-transition: There has already been a dramatic increase in life expectancy, and the average per capita income has surpassed the threshold of $11,900 that accompanies the epidemiological transition; these large changes suggest that Country A has already experiences the epidemiological transition. D. in-transition: The increase in income suggests that Country A is in the process of industrializing and urbanizing; however, the income is still relatively low, so the trend is likely continuing; this suggests that Country A is still in the process of experiencing the epidemiological transition. E. post-transition: The increase in income has led to increased medical interventions and better availability of health care; these large changes are most explained by the shift towards greater medical access; because medical care is more readily available, Country A has already experienced the epidemiological transition.
