Berkeley leptospirosis outbreak prompts pet, public-health precautions

Berkeley health officials report a leptospirosis outbreak near the Eighth & Harrison encampment, with two infected dogs (one fatal) and recent rodent activity; as of Jan. 12 there were no confirmed human cases. Leptospirosis is rare in the U.S., spread mainly through infected animal urine and contaminated water or soil, not airborne, and while most people recover with antibiotics, serious cases can occur. There is a canine vaccine (and vaccines for other animals) but no human vaccine. Officials advise moving away from the red zone, disinfecting gear, avoiding mud and standing water, vaccinating pets, and seeking medical or veterinary care promptly if exposure or symptoms appear.
