Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
It is only possible to get Lyme disease from ticks which carry the bacteria. In high-risk areas, about 10–50% of deer ticks carry the bacteria. These include Eastern states, The Great Lakes ...
For an individual to acquire infection, the feeding tick must also be infected. Not all ticks are infected. In most places in the US, 30-50% of deer ticks will be infected with Borrelia burgdorferi (the agent of Lyme disease). Other pathogens are much more rare. Ticks can be tested for infection using a highly specific and sensitive qPCR procedure.
“These ticks become infected with the Lyme bacterium by biting an infected rodent, bird or other animal.” Symptoms can show up within three to 30 days after a tick bite.
Overall climate is more determinate of tick population and daily weather has a subtle effect on the spread of tick-borne disease. Being mindful of daily weather patterns and vigilantly avoiding exposure to ticks reduces human exposure to Lyme disease. [5] Lyme disease number of cases reported by county 2007 Peak summer weather July 2007. Warm ...
As ticks must be attached for at least six hours to transmit Rocky Mountain spotted fever and more than 24 hours to transmit Lyme disease, frequent checks are crucial in avoiding tick-borne illnesses.
Dr. Leana Wen: In the United States, Lyme disease is the most common vector-borne disease and is transmitted by ticks. People who contract Lyme disease may experience temporary symptoms similar to ...
The ticks that transmit Lyme disease are hard ticks. [4] Ticks often have a preferred host, but may still attach to a different host when called for. Their preferred host may change depending on the tick's stage of development (eg larval vs adult) and the host may or may not carry the transmittable pathogen. [3]
