A California resident has tested positive for the plague.

According to ABC news article, it's the first California plague case in 5 years. El Dorado County health officials were notified by the California Department of Public Health that:

A resident in South Lake Tahoe had tested positive for the plague and that it is thought that person, who is an avid walker, may have been bitten by an infected flea while walking their dog along the Truckee River Corridor, according to a statement released by El Dorado County.
