Final answer:
Factors such as social status and relative wealth could have influenced an individual's exposure and vulnerability to infectious diseases like the plague in the premodern world. In today's world, social factors still play a role in disease vulnerability but modern healthcare systems work to eliminate social disparities.
Step-by-step explanation:
In the premodern world, factors such as social status and relative wealth could influence an individual's exposure and vulnerability to infectious diseases like the plague.
For example, social status could determine access to healthcare, affecting vulnerability. Wealth, on the other hand, did not necessarily ensure isolation from disease.
In today's world, social factors still play a role in disease vulnerability to an extent, but modern healthcare systems aim to eliminate social disparities in disease vulnerability
