Uncontacted Peoples

Uncontacted people, also referred to as isolated people or lost tribes, are communities who live, or have lived, either by choice (people living in voluntary isolation) or by circumstance, without significant contact with globalised civilization. Few people 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 and New Guinea. Knowledge of the existence of these groups comes mostly from infrequent and sometimes violent encounters with neighbouring tribes, and from aerial footage. Isolated tribes may lack immunity to common diseases, which can kill a large percentage of their people after contact.
