With four new reports, more than half of the rabid bats to turn up in Los Angeles County during 2014 have been discovered in the Santa Clarita Valley.

Four more rabid bats were found in the Santa Clarita Valley in the last couple of weeks, bringing the total to 11 out of 21 reported cases in the county, according to a running total kept by the Los Angeles County Department of Public Health.

The latest reported case was a bat found alive outside a home in Saugus, although it’s not clear when that was.

Two of the new cases were discovered in Newhall in the months of July and August, and one was discovered alive outside a home in Stevenson Ranch in July.

The bat found in Newhall in July was alive and hanging on the side of a house during the day, and the August Newhall bat was discovered dead while two dogs played with it, according to the report.

Neither dog was up-to-date on its rabies vaccines, so both were placed under a six-month home quarantine.

County health officials don’t have an explanation for the rise in rabies cases, which has jumped to about 40 cases per year — approximately four times the number of reported cases compared to early statistics from the 1960s

Fewer than one percent of bats have rabies, but health officials warn residents not to touch any bats seen alive or dead on the ground and to immediately call Animal Control at 661-257-3191.
