What tribes have not been contacted?

As of now, there are approximately 100 uncontacted tribes around the world, primarily located in the Amazon rainforest, particularly in Brazil and Peru. These tribes, such as the isolated groups in the Vale do Javari region, have chosen to remain untouched by modern society. Efforts to protect their land and rights are critical, as contact can expose them to diseases and disrupt their traditional ways of life. Other regions with uncontacted tribes include parts of Papua New Guinea and the Andaman Islands in India.
