Los Angeles County's newest record has prompted a warning from health officials: beware of rabid bats.

So far this year, 45 cases have been confirmed, according to the Department of Public Health. The previous record of 38 rabid bats was set in 2011.

Typically, there are only 10 cases a year, according to the DPH.

"The reason for the increase in rabid bats is unclear. Regardless, it is important that everyone understand the potential dangers posed to themselves and their pets as most of these rabid bats have been found in and around homes," DPH Director Jonathan E. Fielding said in a statement.

If exposed to a bat, health officials recommend seeking immediate medical attention.

It's been more than 50 years since a locally acquired case of human rabies has been confirmed in Los Angeles County.
