A South Lake Tahoe resident has tested positive for the plague — yes, the same pest-transmitted disease estimated to have killed 25 million Europeans in the Middle Ages.

Public health officials said the person may have been bitten by an infected flea while camping in the South Lake Tahoe area.

Health officials in California identified a positive case of plague in a Lake Tahoe resident. El Dorado County officials said in a release that they have notified the California Department of Health that a resident from South Lake Tahoe has plague.
