Dengue fever is believed to have originated in Southeast Asia and Africa, with historical records suggesting its presence as early as the 17th century. The disease is caused by the dengue virus, transmitted primarily by Aedes mosquitoes. Over time, it has spread to tropical and subtropical regions around the world due to factors like urbanization and global travel. Today, dengue fever is endemic in many countries, particularly in Southeast Asia, Latin America, and the Caribbean.
