00:00Why is access to this island strictly forbidden and potentially deadly?
00:05Not only is it prohibited to approach it, but if you try, you might die.
00:09This is North Sentinel Island, a small isolated piece of land in the middle of the Indian Ocean,
00:15home to one of the last uncontacted communities in the world, the North Sentinelese.
00:19These people live in a society that has remained unchanged for thousands of years.
00:24They don't use phones, the internet, or electricity.
00:27But what's even more fascinating is that they reject any contact with the modern world.
00:33Anyone who approaches the island is met with arrows and spears.
00:37But why is this island so strictly protected?
00:40The answer is simple.
00:41The Sentinelese have no immunity to diseases that are common to us, like the flu or measles.
00:47A single contact with the outside world could wipe out their entire population.
