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.”
