The Cholbon tribelet of the Northern Valley Yokuts tribe originally inhabited the area now called Mountain House, according to the Mountain House Community Services District.

In addition, measles and some of our other “childhood” diseases are more likely to kill infected adults than children, and all adults in the tribelet are susceptible.

As tragic modern experience with Amazonian Indians and Pacific Islanders confirms, almost an entire tribelet may be wiped out by an epidemic brought by an outside visitor—because no one in the tribelet had any antibodies against the microbe.

Having killed most of the tribelet, the epidemic then disappears.

Since the disease may take a very long time to kill its victim, the victim remains alive as a reservoir of microbes to infect other members of the tribelet.
