Ticks are insects known for attaching to and sucking blood from land-dwelling animals (specifically vertebrates). [1] Ticks fall under the category of 'arthropod', and while they are often thought of in the context of disease transmission, they are also known to cause direct harm to hosts through bites, toxin release, and infestation.
Then, notice if you develop a rash or any flu-like symptoms in the following weeks, he adds. It can take up to 30 days for Lyme disease symptoms to appear after a tick bite, the CDC says. Signs ...
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]
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.
Anaplasmosis, caused by A. phagocytophilum bacteria, is spread by deer ticks and is the most common co-infection with Lyme disease. Symptoms include fever, headache, chills and muscle aches.
Ehrlichiosis is a bacterial infection spread by ticks that also causes flu-like symptoms. Ticks continue to expand into new areas, increasing the chances of an Ohioan encountering one, McDermott said.
"Bull's-eye" STARI rash. Diagnosis is based on a circular "bull's-eye" rash at the site of infection called erythema chronicum migrans, which is very similar to that seen in Lyme disease. However, the symptoms of STARI are mild, and resemble influenza, with fatigue, muscle pains, and headache. [1] Fever is sometimes seen, but is not characteristic.
According to the CDC, ticks can transmit bacteria, viruses, and pathogens that lead to human illness through their feeding process. 4 worst ticks in Greenville, South Carolina: What to know about ...
