Lyme disease is a bacterial infection that is transmitted by the tick bite. Symptoms of Lymes disease most shells encountered are fever, fatigue, headache and eritem. Because these symptoms are encountered in many other diseases, must be done before a differential examination to diagnose.Isodex scapularis, the deer tick or black is the vector tick infectious bacterium Borrelia burgdorferi. It is responsible for Lyme illness. It normally lives in mice, squirrels and other small animals.

Tick hasthree developmental stages: larva, nymph and adult. When an infected tick feeds on blood of a sick animal, and ingests the bacteria it will live in the intestine. These ticks and the next meal will infect another animal or human. Most cases of infection occur in late spring or summer when the tiny tick nymphs are most active in the environment and human activities are frequent. The rest, live in the fur deer ticks, which do not get sick from Lyme disease. Treatment for symptoms of Lymes disease is with antibiotics.

-Causes:
The deer tick is the principal vector of Lyme disease but has not been demonstrated whether other ticks may or may not become vectors.
Other modes of disease transmission:

-People contacts;

-Transmission during pregnancy;

-Blood transfusions;

-Animals.

Interpersonal transmission: not yet proved that the disease could transmit and through kissing, touching, sex with an infected person.
Disease during pregnancy can lead to infection in the placenta and abortion have not yet registered negative effects on the fetus if the mother is treated properly with her  pointed antibiotics .No disease transmission yet through breast feeding.

Although there were no recorded cases of infection by another blood transfusion, it was found infecting the bacteria survive in blood stored for donations. The patients can donate 12 months after the last dose of antibiotic treatment.
Pets can do Lyme disease but no evidence that they may become vectors for the human body, instead they bring ticks into the house and garden.
Disease is not transmitted through the squirrel or deer meat, but it should still cook to appropriate temperatures.

-Symptoms of Lyme disease
The first sign of infection is usually a circular called migratory erythema. It occurs in 70-80% of infected people and begins to tick sting area after a period of three to thirty of days. A distinguishing feature of redness is expanding gradually over several days; reaching up to 30 cm. Erythema may become normal colored center as it expands as compared with ox-eye. Can be hot and painful. Some people develop other flushes in different areas over several days.
Other symptoms of Lyme disease:

-Fatigue;

-Chills;

-Fever;

-Headache;

-Cramps;

-Lymphadenopathy.

In some cases, redness may be missing.

Left untreated, the infection spreads to other parts of the body in a few weeks, cause a variety of symptoms:

-Motor weakness of both sides of the face, Bell's Palsy;

-Serious headache and neck stiffness due to meningitis;

-Poseur-sore  which causes insomnia;

-Throb and dizziness due to arrhythmia;

-Migration of joint-pain.

Most symptoms resolve even without treatment. After months of infection, 60% of patients will have intermittent arthritis with severe joint pain and swelling, the knees were especially affected. Other 5 percent will develop neurological chronic pain states, tingling, decreased ability to concentrate and short-term memory. Most patients respond to   treatment, if it's initiated early in disease, a small percentage will have symptoms after years: muscle pain, arthritis, tiredness, insomnia, cognitive disabilities.
