Bite reporting

By Law, all animal bites to people must be reported to our office. Bites from wildlife (including bat exposures) to pets are also reportable. Inspectors follow up on every bite report received. The biting animals are usually not taken away from their owner. In most cases, home quarantines are implemented to ensure the animal does not have rabies (see flowcharts below for quarantine lengths). It is therefore crucial to enter the biting animal's information when submitting bite reports. Scratches, as well as bites from rodents and rabbits do not transmit rabies - these incidents are not reportable.

Rabies

In Los Angeles County, exposure to bats or bites from animals in rabies-endemic countries are considered high risk for rabies. While most bats in the wild are not infected with the virus, any contact with bats should be thoroughly investigated to rule out rabies exposure. Bites from other local wildlife (skunks, raccoons, opossums, etc) represent a moderate risk. Bites from local dogs or cats are low risk of rabies.

These recommendations are valid for Los Angeles County only - rabies vectors may differ in other parts of the country and abroad. Veterinarians should ask owners about the pet's origin, as animals coming from abroad may be at increased risk of rabies and other foreign diseases.

Pets and children

Pets can make great companions for children, teaching important values such as compassion and responsibility. However, children can be at higher risk for several pet-related illnesses. In Los Angeles County, the highest rate of bites reported occur in children aged 4-9. Children may also be at higher risk of zoonotic diseases transmitted fecal-orally or by direct contact (flea-borne diseases, gastrointestinal parasites, ringworm and more). Children should never be left with pets without supervision, and should always wash their hands after playing outside or with a pet. In addition, pets should be up-to-date on their vaccines and preventive care.

Pets and pregnancy

Pregnant women should exercise caution around their pets in order to prevent infection from zoonoses or injury to themselves (e.g. bites). There is no need to remove a pet from a household where a woman is expecting. Toxoplasmosis in cats is more commonly transmitted to people through eating undercooked meat. Only cats that go outdoors and ingest rodents can be infected with Toxoplasma gondii. In addition, healthy cats typically shed the parasite once in their lifetime. Other zoonoses that can constitute an increased risk during pregnancy include lymphocytic choriomeningitis virus (rodents) and listeriosis (raw milk).

Pets and immune-suppressed populations

Chemotherapy, organ transplants, and other conditions (e.g. HIV) that affect the immune system may increase risks of infections from contact with animals. Precautions should be taken to reduce the likelihood of disease transmission from pets to immune-suppressed persons (hand washing, avoiding licks to the face). Pets of immune-suppressed owners should be up-to-date on their vaccines and other preventive care.

Vaccination guidelines

In California, rabies vaccination in dogs is mandatory. Some cities in Los Angeles County have enacted their own rabies vaccination requirements for cats (see list below). Nevertheless, it is recommended to vaccinate all cats against rabies, as rabid bats have been found inside homes of indoor-only cats. The minimum age for rabies vaccination in dogs and cats changed from 4 months to 3 months in January 2014. Other pet vaccines should be administered according to the guidelines below.

Zoonotic diseases and employee safety

Veterinary personnel may be at increased risk of infection from a zoonotic pathogen such as rabies, leptospirosis, or flea-borne typhus. In addition, animals may become infected by diseases from humans (influenza, MRSA) or act as a sentinel for diseases that are present in the environment (Valley fever, West Nile virus). In Los Angeles County, any infectious disease in animals is reportable to our office (see priority list below). Animal disease surveillance is an integral part of keeping our communities safe from infectious pathogens. Asking animal owners about concurrent human illness can help identify zoonotic diseases outbreaks.
