CDC warns of rabies surge across California counties

Multiple counties report sharp increases in rabid bats and animals, with Berkeley detecting five cases in nine months versus a typical one to two annually.

What to know

  • Five rabid bats detected in Berkeley since January 2026—a 5x increase over the historical annual average of one to two cases.
  • Rabies is almost always fatal once symptoms appear, making early detection and animal exposure prevention critical.
  • Increases in rabid animals are concentrated in three major California regions: Berkeley, Los Angeles, and San Diego.

“In the Bay Area, Berkeley officials issued a warning late last month after five rabid bats were detected since the start of the year. That is a significant increase from the normal one to two detections annually.”
