A Deadly Bacteria Threatens California Dogs and Residents
A recent outbreak of leptospirosis, a potentially fatal bacterial disease, has been reported in Berkeley, California, sparking concerns among local residents and pet owners. The alert, issued by health authorities, warns of heightened risks for dogs and people after a period of heavy rainfall created favorable conditions for the bacteria to thrive.
The disease is typically spread through the urine of infected animals - primarily rats - contaminating soil and stagnant water. According to Dr. Monica Gandhi, an infectious disease physician at UCSF, dogs are particularly at risk due to their tendency not to avoid puddles of water like humans do. "Dogs don't avoid puddles the way people do," she told SFGATE. "They're much more likely to be exposed."
The combination of warm weather followed by recent storms has created optimal conditions for leptospirosis survival and transmission, with the bacteria able to persist in soil or water for up to a month. The city has designated the Harrison Street area as a 'red zone' and urged residents to move away from the encampment to enable focused cleanup, rat eradication, and public safety measures.
Pet owners are being advised to vaccinate their animals against leptospirosis, while owners of free-roaming cats should also consider vaccination. All pet owners are encouraged to prevent animals from drinking potentially contaminated water. The city has posted warnings, conducted environmental testing, and called on residents to seek medical care immediately if they develop flu-like symptoms after spending time in the encampment area.
A public health investigation is ongoing, with cleanup and rat eradication activities expected to take at least 30 days - the typical lifespan of leptospirosis in soil. The city is urging caution, advising neither dogs nor people to wade in, or drink from, nearby water, mud, puddles, or Codornices Creek.
