SAN JOSE (KCBS)— With anywhere from 200 to 300 residents, “The Jungle” has been described as one of the largest homeless encampments in the nation. Sitting on the banks of San Jose’s Coyote Creek, health officials say it’s become a breeding ground for sexually transmitted diseases, including HIV.

Mercy Egbujor, a nurse with Valley Homeless Healthcare, said there’s been a disturbing rise in the number of HIV cases at the encampment as well as other communicable diseases like gonorrhea and Chlamydia.
