What are the effects of endemic and epidemic diseases on society? Select four answers.The diseases continue when cycles of infection occur.The productivity declines when people are too sick to work.The population decreases from low birth rates and high death rates.The population is younger when life expectancies are shortened.The government becomes stronger as the population becomes weaker.

Endemic diseases remain present in a population, and epidemics can recur, so cycles of infection may continue (A). Illness keeps people from working, lowering productivity (B). High death rates—and sometimes lower birth rates—can cause the population to shrink (C). When life expectancy falls, fewer people live to older ages, making the population younger overall (D). A weaker population does not necessarily make the government stronger, so E is not correct.
