Story summary

In June, two people living in a filthy RV near an encampment on Eighth and Harrison streets in Berkeley, California, were infected with leptospirosis, a deadly flu-like disease spread through contact with urine from infected animals. One patient died after being hospitalized for an extended period, while the other recovered. The same illness was later linked to rats in the nearby encampment, prompting officials to declare it a fire hazard and public nuisance due to its rat population. Following court approval, city authorities began clearing the encampment on Tuesday, addressing ongoing public health and safety concerns.
