Final answer:
Diseases reemerge because of rapid global travel and unequal healthcare access; this inequality is showcased through societal indicators like IMR and LE. Developed countries spend about 11% of GDP on healthcare, with the US at 17%, while developing countries spend significantly less, leading to more health challenges and lower life expectancies.
Step-by-step explanation:
Diseases can reemerge due to factors such as globalization, which facilitates rapid spread, and unequal access to medical advancements between developed and developing countries. Societal reflection of Infant Mortality Rates (IMR) and Life Expectancy (LE) are indicators of the effectiveness of the healthcare systems and the overall health of a population. On average, a developed country spends about 11% of its GDP on healthcare, while the United States, an outlier, spends around 17%. In contrast, developing countries typically have far less to spend on healthcare, both in terms of GDP percentage and absolute financial resources.
In many developed nations, universal healthcare is accessible and is often funded through taxation, leading to generally better outcomes than in the U.S., despite its higher spending. However, developing countries face multiple challenges, including high infant mortality rates and low average life expectancies, due to inadequate health and medical resources. The role of organizations like Doctors Without Borders and WHO is crucial in addressing the basic health needs in these regions.
When comparing global health spending, it's evident that higher expenses do not always correlate with better outcomes, as seen in the U.S., which has a relatively high IMR compared to countries that spend less on healthcare. This complexity highlights the interplay of various factors, including poverty, healthcare systems, and societal roles.
