Human migration, infectious diseases, plague, global health crisis - historical evidence

This study examines the transmission of infectious diseases through historical studies, focusing on colonialization, slave trade, religion spread, and transcontinental and island trade. Emerging diseases like leprosy, Black Death, syphilis, malaria, Spanish flu, and COVID-19 have become significant contributors to global health crises. The study uses four stages: heuristics, critique, interpretation, and historiography. It focuses on migration, pandemics, and global health crises, using relevant literature. The findings suggest that many diseases have reached pandemic proportions due to their rapid dissemination and the influence of migration caused by historical factors such as ancient travel culture, colonialism, and modern times. The evolution of contemporary language also facilitates international mobility. The research examines the issue of disease distribution resulting from the long-standing global migration process, focusing on how migration has played a significant role in the occurrence of pandemics, outbreaks, and global health crises throughout history. The migration of Homo Sapiens from East Africa to regions outside Africa led to the development of language, culture, and disease transmission. The domestication of animals resulted in the emergence and transmission of disease mutations, leading to the worldwide dissemination of infectious diseases like leprosy, Black Death, syphilis, malaria, and COVID-19.
