There are hundreds of species of ticks worldwide, but only a few bite humans and transmit the bacteria that causes Lyme disease. According to the CDC the two ticks that can cause Lyme disease...
Pathogens: This tick transmits Lyme disease, Borrelia miyamotoi disease (a relapsing fever Borreliosis), babesiosis, ehrlichiosis, and human granulocytic anaplasmosis (HGA). It also is suspected of transmitting Bartonella to humans. Although all life stages of this tick can bite, nymphs and adult females are thought to be the primary cause of ...
Lyme disease is caused by bacteria that is spread to humans by tick bites. The ticks that carry the spirochete are: Black-legged deer tick (northeastern, mid-Atlantic, and North-Central U.S.)
As of 2019, Lyme disease is the most often diagnosed tick-borne illness. Here are images of unfed, human-biting ticks. The images also show where the ticks might be found in the U.S. and the diseases they're known to carry.
Deer ticks that carry Lyme disease are widespread. They are mostly found in the upper Midwest, the northeastern and mid-Atlantic states, and in south central and southeastern Canada. The castor bean tick is found throughout Europe.
Lyme disease bacteria causing human infection in the United States are spread to people by blacklegged (Ixodes) ticks. In general, infected ticks must be attached for more than 24 hours to transmit infection; prompt tick removal can prevent transmission.
The Ixodes tick, commonly called a black-legged tick, are ticks that carry Lyme disease. In the east and upper midwest regions of the United States, the primary tick species is Ixodes scapularis (or deer tick) and the related western U.S. version is the Ixodes pacificus (western black-legged tick).
In high-risk areas, about 10–50% of blacklegged ticks carry the bacteria. These high-risk areas include: Eastern states, primarily New England and the mid-Atlantic. The Great Lakes Region and Northern Midwestern states, especially Wisconsin and Minnesota.
Lyme disease is a bacterial infection spread to people through the bite of 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.
In most cases, a tick must be attached for 36 to 48 hours or more before the Lyme disease bacterium can be transmitted. If you remove it within 24 hours, the risk is greatly reduced....
