“The bat was found between the Multipurpose and Performing Arts Buildings during lunch time on Jan. 29,” said Dr. Seira Kurian, area medical director for the health department. “Los Angeles County Department of Public Health is working with school officials to notify parents about the bat and determine if any children were exposed to rabies.”

Health officials explained rabies is an infectious viral disease that affects the nervous system of humans and other mammals. The disease is transmitted through the bite of an animal with rabies.

Any students who came in direct contact with the bat and may have been bitten are urged to receive anti-rabies treatment as the disease is deadly.

“Because bats have small teeth which may leave marks that are not easily seen, the virus may be transmitted even in the absence of an obvious wound,” Kurian stated. “Rabid bats have been found throughout Los Angeles County.”
