Which tickborne diseases have been confirmed in your neighborhood?

The following maps are color coded to indicate the number of reported positive cases of ehrlichiosis, Lyme disease, heartworm disease, and anaplasmosis in dogs within the Southwest Gulf Coast area. Due to how many dogs go untested for vector-borne diseases, the actual number of dogs infected by ticks is likely higher than shown in these maps. The data was sourced from over 10,000 veterinary clinics, telephone surveys, and IDEXX references laboratories results. Review the data and prevent your pets from becoming a statistic with proper vaccination through your local vet.

 

Ehrlichiosis / Ehrlichia

Ehrlichiosis is the general name used to describe several bacterial diseases that affect animals and humans. Human ehrlichiosisis a disease caused by at least three different ehrlichial species in the United States: Ehrlichia chaffeensis, Ehrlichia ewingii, and a third Ehrlichia species provisionally called Ehrlichia muris-like (EML). Ehrlichiae are transmitted to humans by the bite of an infected tick. The lone star tick (Amblyomma americanum) is the primary vector of both Ehrlichia chaffeensis and Ehrlichia ewingii in the United States. Typical symptoms include: fever, headache, fatigue, and muscle aches. Usually, these symptoms occur within 1-2 weeks following a tick bite. Ehrlichios is diagnosed based on symptoms, clinical presentation, and later confirmed with specialized laboratory tests. The first line treatment for adults and children of all ages is doxycycline.  Ehrlichiosis and other tickborne diseases can be prevented. Summary from Centers for Disease Control and Prevention.

 

Lyme disease

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks.  Laboratory testing is helpful if used correctly and performed with validated methods. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics. Steps to prevent Lyme disease include using insect repellent, removing ticks promptly, applying pesticides, and reducing tick habitat. The ticks that transmit Lyme disease can occasionally transmit other tickborne diseases as well. Summary from Centers for Disease Control and Prevention.

 

Heartworm disease

Heartworm is preventable, but serious and potentially fatal, parasite that primarily infects dogs, cats, and ferrets. It can also infect a variety of wild animals, including wild canids (e.g., foxes, wolves, coyotes), wild felids (e.g. tigers, lions, pumas), raccoons, opossums, and pinnipeds (e.g., sea lions and seals), as well as others. There have been documented human infections, but they are thought to be rare and do not usually result in signs of illness. Summary from AVMA.

 

Anaplasmosis

Anaplasmosis is a tickborne disease caused by the bacterium Anaplasma phagocytophilum. It was previously known as human granulocytic ehrlichiosis (HGE) and has more recently been called human granulocytic anaplasmosis (HGA). Anaplasmosis is transmitted to humans by tick bites primarily from the black-legged tick (Ixodes scapularis) and the western black-legged tick (Ixodes pacificus). Of the four distinct phases in the tick life-cycle (egg, larvae, nymph, adult), nymphal and adult ticks are most frequently associated with transmission of anaplasmosis to humans. Typical symptoms include: fever, headache, chills, and muscle aches. Usually, these symptoms occur within 1-2 weeks of a tick bite. Anaplasmosis is initially diagnosed based on symptoms and clinical presentation, and later confirmed by the use of specialized laboratory tests. The first line treatment for adults and children of all ages is doxycycline. Anaplasmosis and other tickborne diseases can be prevented. Summary from Centers for Disease Control and Prevention.
