Analyzing patterns in tick-borne diseases
(Distribution)
The veterinary lab that Dr. Louis uses participates in a research project that collects data on tick-borne diseases in dogs. The US Centers for Disease Control and Prevention (CDC) collects similar data on tick-borne diseases in humans. Researchers can use this data to recognize patterns in the dog and human tick-borne infections. For example, researchers can measure the incidence rates of tick-borne infections to monitor health needs related to tick exposures.

Researchers decided to focus on the blacklegged tick because this tick can carry several diseases that are transmissible to humans, including the pathogen that causes Lyme disease. In 2018, the CDC developed a map to illustrate the geographic distribution of the blacklegged tick in the United States. This map is shown below.
