Question

stage 4 of the epidemiological transition model is the stage of pestilence and famine reemergence of infectious and parasitic diseases delayed degenerative diseases receding pandemics

Explanation:

The epidemiological transition model has several stages. Stage 4 is characterized by the reemergence of infectious and parasitic diseases. This can be due to factors like antibiotic resistance, globalization (which aids in disease spread), and changes in human behavior or environmental conditions. For example, the resurgence of malaria in some regions (due to vector resistance to insecticides) or the spread of new infectious diseases like Zika (which spread rapidly due to global travel) are manifestations of this stage. In contrast:

• "Pestilence and famine" is more associated with earlier stages (like Stage 1) of the model when societies had high mortality from acute, infectious diseases and poor living conditions leading to famine - related deaths.
• "Delayed degenerative diseases" is more in line with Stage 3, where chronic non - infectious diseases (e.g., heart disease, cancer due to aging populations and lifestyle factors like diet and lack of exercise) are the main cause of mortality.
• "Receding pandemics" was thought to be a feature of an idealized progression after Stage 2 (age of receding pandemics), but in reality, Stage 4 shows that pandemics (in the form of reemerging or new infectious diseases) do not fully recede.

Answer:

reemergence of infectious and parasitic diseases
