Identify at least one organization that works to improve global health, such as the WHO, CDC, or UN, and briefly explain their role.

The World Health Organization (WHO) is a specialized agency of the United Nations that works to promote health, keep the world safe, and serve the vulnerable. Its role in improving global health is significant, as it is responsible for providing leadership on global health matters, shaping the health research agenda, setting norms and standards, and monitoring and assessing health trends. The WHO works with its member states to develop policies and strategies that address a wide range of health issues, from infectious diseases and non-communicable diseases to mental health and environmental health. The WHO also plays a crucial role in responding to global health emergencies such as pandemics, natural disasters, and humanitarian crises. In summary, the WHO works tirelessly to improve global health by setting standards and guidelines, promoting research, and providing technical support and leadership to countries to prevent, detect, and respond to health emergencies.
