Lyme disease begins as an infection caused by black-legged ticks. Usually living in wooded areas such as forests, these ticks can attach themselves to the skin of humans and bite them, infecting them a bacterium called Borrelia burgdorferi (CDC 2008). Several days or weeks after such a bite, a person usually begins to develop ringed rashes around the bitten area. These rashes can be painful and can cause swelling, however this is not always the case.

[...] This rash, expanding reddish is often-associated with ?flu-like symptoms? (www.medicinenet.com 2008). There are usually three phases to Lyme disease, which include early localized disease (skin inflammation), early disseminated disease (with heart and nervous system), and late disease (leading to motor and sensory nerve damage and brain inflammation as well as arthritis) (www.medicinenet.com 2008). The early phase, which usually occurs several weeks after the time, occurs with rashes and lesions occurring around the area of the bite, often resembling a ?bull's eye.? Not all patients get the rash, whoever there is usually redness of the skin, a feeling of ?fatigue, muscle and joint stiffness, swollen glands, and headache resembling symptoms of a virus infection? (www.medicinenet.com 2008). [...]


[...] Lyme disease follows a cycle of feeding and remaining relatively inactive. The late spring and summer are usually the peak time for transmission, since many people tend to travel through forests during this time. Another reason why transmission occurs during this time is that young ticks, in their attempt to grow and develop, have an enormous hunger for animal (or human) blood. There are three feeding stages of a tick, which live for about two years: larvae, nymph and adult. [...]


[...] When hunting for deer, it is possible to acquire Lyme disease, but this is not a possibility for meat that is properly cooked, because Lyme disease cannot survive this way in a deer. One major risk is that, if left untreated, a pregnant woman who acquires Lyme disease can spread it through the placenta and this can be deadly for a fetus, however the use of antibiotics prevents this risk (CDC 2008). Effects & Symptoms Lyme disease can have different affects no different people, especially with regard to the ringed rashes that develop on the skin. [...]
