Tick-Borne Disease Facts

At least 49 species of ticks are fond in the state of California.

Exotic ticks potentially carrying diseases such as: Babesiosis, Heartwater, and Colorado Tick Fever Virus have been introduced into California repeatedly.

Ticks carrying deadly pathogens such as the Tick-borne encephalitis virus and Heartwater disease can be carried long distances by migrating birds.

California’s cattle producers lose an estimated 5% to 10% of the beef calf crop (45,000 to 90,000 calves) annually to a single tick-borne disease – Epizootic Bovine Abortion (EBA)

Tick control measures and vaccination against diseases such as bovine anaplasmosis incur additional costs to cattle producers yearly.

Cattle and deer often support ticks species that carry diseases transmissible to humans such as Lyme disease and Human Granulocytic Anaplasmosis.

Most tick-borne diseases affecting cattle in California lack vaccines against them or require long term antibiotic therapy to treat them.
