What is the term for the exchange of goods a disease brought to the new world?

The term for the exchange of goods, including diseases, between the Old World and the New World is called the "Columbian Exchange." This phenomenon began after Christopher Columbus's voyages in the late 15th century and involved the transfer of various plants, animals, and pathogens, significantly impacting both sides. The exchange led to dramatic demographic and ecological changes, including the introduction of diseases like smallpox to the indigenous populations of the Americas.
