The World Health Organization (WHO) is the global public health agency (GCU, 2018). Within the United States government, the Centers for Disease Control and Prevention (CDC) works nationally and globally to protect the public health of the United States (GCU, 2018). The CDC works on behalf of the United States with other partners such as the WHO in programs that aim to protect our nation’s health concerns. Because of the ubiquitous nature of global travel, disease transmission can quickly become a global problem that knows no borders, and therefore often the global health concerns are also national health concerns. The CDC and the WHO decide what public health threats should be reportable and local and state public health departments operate and provide surveillance on a smaller, more local level.
The WHO determined the Sustainable Development Goals to expand the mission of human health rights and health promotion (GCU, 2018). While these SDG factors vary greatly throughout the globe, their existence and persistence can have negative global impacts. War and disease can have large, regional and global impacts that have a ripple effect on the health of other parts of the world. World partners and stakeholders send aid and respond to these events in order to mitigate the potential impact (GCU, 2018). Climate change and climate disasters will continue to grow into a huge challenge to our global health security (Gore, 2017). As climate events occur, so will food scarcity and global migration of species poleward. Civil unrest and power struggles result, leading to conflict. Food scarcity, violence, trauma and mental health impacts, and war all negatively impact social determinants of health (GCU, 2018). Warmer temperatures also favor insects that harbor vector-borne illnesses such as Lyme disease and Zika (Gore, 2017). Climate disasters impact food, contaminate water, and cause trauma and displace people from shelter (Gore, 2017). Combating climate change will be one of the greatest public health challenges of all time.
