Other Tick-Borne Diseases (TBDs)

According to recent CDC study (Rosenburg, et al. 2018), vector-borne diseases have more than tripled in a 13 year time period and are a growing risk to human, pet, livestock and wildlife health both nationwide and worldwide.  Tick-borne diseases (TBDs) more than doubled in 13 years and were 77% of all vector-borne disease reports. Lyme disease accounted for 82% of all tick-borne cases, but spotted fever rickettsioses, babesiosis, and anaplasmosis/ehrlichiosis cases also increased. During this same time period, seven new tick-borne germs have been identified that can infect people in the US.

In addition to transmitting increased numbers of infections, the bite of a tick may trigger other conditions including tick paralysis and Alpha-Gal meat allergy. Alpha-gal may result in lifelong, and life threatening allergies to meat and meat products.

Many tick species are expanding in range and prevalence as habitat and climate changes occur, as wildlife migrate or expand populations, and as humans, pets and livestock travel.

There are at least 20 tick-borne diseases TBDs that have been identified as human pathogens within the United States alone, with Lyme disease currently being the most reported.

Only 7 of these diseases are currently considered reportable in the State of Colorado.

Though Colorado Tick Fever is the most commonly reported tick-borne disease in Colorado, little is being done regarding surveillance of the many other ticks and tick-borne diseases that may impact human health in Colorado. Companion Animal Parasite Council data is showing an increase in cases of TBDs including Lyme disease, Anaplasmosis and Ehrlichiosis in dogs in Colorado, indicating that risk to human health may be greater than what is currently being reported.

Regardless of where exposure to tick-borne pathogens are occurring, many individuals, families and pets living in Colorado have been impacted by these diseases and the prevalence of many of these diseases continues to rise nationwide and worldwide. In the presence of Lyme disease, many of the other TBDs are considered co-infections. Co-infections can make manifestation of disease, diagnosis and treatment more complex.

Lyme and other Tick-borne disease is a global issue. The CDC provides additional information regarding tick-borne diseases that you may encounter when traveling abroad.
