Uncontacted Amazon tribes
Uncontacted peoples, also referred to as isolated peoples or lost tribes, are communities who live, or have lived, either by choice (peoples living in voluntary isolation) or by circumstance, without significant contact with globalized civilization. Few peoples have remained totally uncontacted by global civilization. Indigenous rights activists call for such groups to be left alone, stating that it will interfere with their right to self-determination. Most uncontacted communities are located in densely forested areas in South America, New Guinea, India, and Central Africa. Knowledge of the existence of these groups comes mostly from infrequent and sometimes violent encounters with neighboring tribes, and from aerial footage. Isolated tribes may lack immunity to common diseases, which can kill a large percentage of their people after contact.
On January 18, 2007, FUNAI reported that it had confirmed the presence of 67 uncontacted tribes in Brazil, up from 40 in 2005. With this reported increase, Brazil has surpassed the island of New Guinea (divided between Indonesia and Papua New Guinea) as the region having the highest number of uncontacted tribes.
