Tick born diseases

Tick born diseases are the diseases transmitted by ticks.Tick born diseases can be caused by viruses, or parasites. Most people become infected through tick bites during the spring and summer months.

Lyme disease

Lyme disease is an illness caused by infection within a bacterium (Borrelia burgdoferi) that is caught by being bitten by a tick. It causes an acute severe illness with a skin rash. It has been suggested that some people with the fatigue and muscle aches typical of chronic fatigue syndrome/ME really have chronic untreated lyme disease.

Relapsing fever

An acute infectious disease caused by spirochetes of the genus Borrelia, relapsing fever is transmitted to humans by lice or tics and is characterized by relapse and remissions.

Rodents and other wild animals serve as the primary reservoirs for borrelia spirochetes. Humans can become secondary reservoirs but cannot transmit this infection by ordinary contagion; however, congenital infection and transmission by contaminated blood are possible.

Q fever

Coxiella burnetii, the only species in the Coxiella genus, causes Q fever. The Q stands for query because the cause of this infection was not known when it was first described in the 1930s and the investigators queried its cause. Q fever is a zoonotic disease that is often transmitted with exposure to cattle, sheep, and goats. The most common mode of transmission to humans is inhalation or aerosols or dust contaminated with dried birth fluids or excreta from infected animals. Direct animal contact is not required for transmission to occur. Infections via ingestion of contaminated dairy products and human to human transmission via sexual contact  or during parturition have been rarely reported.

Rocky mountain spotted fever

Rocky mountain spotted fever is the most severe and frequently reported reckettsial illness in the United States. A rickettsia is a bacteria of the genus Rickettesiae; these bacteria are carried as a parasite by many ticks, fleas, and lice and cause disease in humans. Rocky mountain spotted fever is caused by the bacteria Rickettesia rickettsii. The American dog tick and rocky mountain wood tick are the primary vectors, although others have been implicated.


Babesiosis is a rare, potentially life threatening disease caused by the babesia microti parasite, which is spread to people through the bites of infected ticks that live on animals such as deer and mice. Babesiosis also can be transmitted through blood transfusions. The parasite that causes babesiosis attacks red blood cells. Babesiosis can be mild or severe. Most people who are infected do not become sick. However, older people and people who have an impaired immune system or who have had their spleen removed are at increased risk of developing a severe infection.

Colorado tick fever

Colorado tick fever is a tick born disease which is caused by agent Colorado tick fever virus, a prototype virus of the genus Coltivirus of the family Reoviridae. It is transmitted by tick bite, blood transfusion.
