Global health refers to the health of populations in a global context, emphasizing the interconnectedness of health issues across borders. It encompasses a wide range of topics, including disease prevention, health promotion, and access to healthcare services, aiming to improve health outcomes worldwide. Efforts in global health often involve collaboration among countries, organizations, and communities to address challenges such as infectious diseases, malnutrition, and health inequities. Initiatives like World Health Organization (WHO) play a crucial role in coordinating responses to health crises and promoting sustainable health practices globally.
