The largest population growth in the United States is expected to come from immigration and an aging population. Globalization has led to the spread of chronic diseases in developing countries. It is important to monitor countries' health to identify and prioritize public health needs. Some of the biggest global health challenges include pandemics like COVID-19 and monkeypox, economic and geographic disparities in health care access, and noncommunicable diseases. Environmental factors exacerbated by climate change also influence disease spread.

discuss: Within the United States, the largest population growth is expected to come from
immigration and the development of the older adult population. Globalization has recently
changed the lifestyles of developing countries, resulting in new chronic diseases. Monitoring
the health of any country is essential for identifying and prioritizing public health and
research needs. It is necessary to identify important information such as diseases and
conditions and determine new health policy priority areas, funding, and programs (Holtz,
2012).Some of the significant health issues facing the world population growth in the last
25 years cause the most significant challenges confronting progress in global
health.Pandemics: Pandemics are defined as global disease outbreaks. The current one that
the world is battling is the multi-variant outbreaks of COVID-19. The COVID-19 pandemic
has drawn attention to the deep disparities that persist between and within countries, some
of which are being exacerbated and risk widening even further. On its heels is the
monkeypox outbreak. The spread of monkeypox is questionable as it appears random and
irregular. Catching COVID-19 increases the risk of developing other major health issues
such as cardiovascular disease and diabetes. Infected patients are more likely to be
diagnosed with life-threatening diseases. Vaccination efforts can help, but it’s critical to
address issues at the source by addressing essential areas like health education and
responsible agricultural practices.Economic disparities and access to health care: Despite
relentless progress in the field of medicine, communities across the world still lack access to
primary health education and health care. This results in health disparities, such as high
maternal and infant mortality rates, which are often related to
geography. Noncommunicable diseases: Heart disease, stroke, cancer, diabetes, and other
noncommunicable diseases (NCD) account for 70% of all deaths worldwide. Together, heart
disease and stroke, along with other cardiovascular diseases, are among the most
widespread and costly health problems facing the Nation today, accounting for
approximately $320 billion in health care (Pirani, 2019).Environmental Factors: The Earth’s
average land temperature has warmed nearly 1°C in the past 50 years because of human
activity, global greenhouse gas emissions have grown by nearly 80% since 1970, and
atmospheric concentrations of the major greenhouse gases are at their highest level in
800,000 years. Storms, flooding, droughts, and air pollution make it easier for diseases to
spread across large groups of people. The immediate solution is to provide resources like
bottled water and sanitation technology, but global health must also focus on the
prevention of environmental challenges in the first place. Climate change is thought by

related hazards can include biological, chemical, or physical stressors and can differ in time,
location, population, and severity (National Institute of Environmental Health Sciences
[NIEHS], 2022).ReferencesHoltz, C. (2012). Global health care (2nd ed.). Jones & Bartlett
