Lyme disease
  • Lyme disease is the most common tick-borne
    disease that is caused by the bacteria known as
    Borrelia burgdorferi. Deer ticks, which feed on
    the blood of animals and humans can harbor the
    bacteria and spread it at the time of
    feeding.You're more prone to suffer from Lyme
    disease if you live or spend time in grassy and
    heavily wooded areas where ticks carrying the
    disease thrive. It's important to take some
    common precautions in areas where Lyme disease is
    prevalent.If you are treated with antibiotics
    in the early stages of the disease, you are
    likely to recover completely. In later stages,
    response to treatment can be slower, but the
    majority of people with who are having Lyme
    disease recover completely.

Causes of Lyme disease
  • Lyme disease is caused by the bacterium called
    Borrelia burgdorferi, which is carried primarily
    by deer ticks. The ticks are brown and when
    young, they're often no bigger than the head of a
    pin, which makes them nearly impossible to
    spot. An infected deer tick must bite you to
    suffer from Lyme disease. The bacteria go into
    your skin through the bite and eventually make
    their way into your bloodstream. In most cases,
    to transmit Lyme disease, a deer tick must be
    attached for 36 to 48 hours.If you found that
    an attached tick that appears like swollen, it
    may have fed long enough to spread bacteria.
    Extracting the tick as early as possible can
    prevent infection.

Complications related with Lyme disease
  • If left untreated, Lyme disease can cause 
  • Chronic joint inflammation (Lyme arthritis),
    particularly of the knee
  • Neurological symptoms, like facial palsy and
    neuropathy
  • Cognitive defects, like impaired memory
  • Heart rhythm irregularities

Treatment for Lyme disease
  • Antibiotics are used to treat Lyme disease.
    Generally, recovery will be much quicker and
    complete as early as the treatment
    begins.Antibiotics
  • Antibiotics - These are the standard treatment
    for early-stage Lyme disease. These generally
    involve doxycycline for adults and children older
    than 8, or amoxicillin or cefuroxime for adults,
    younger children, and pregnant or breast-feeding
    women. A 15- to 21-day course of antibiotics is
    generally advised, but some studies suggest that
    courses lasting 10 to 14 days are equally
    effective.
  • Intravenous antibiotics - If the disease involves
    the central nervous system, your doctor may
    advise treatment with an intravenous antibiotic
    for 14 to 28 days. This is effective in
    eliminating infection however it may take some
    time to recover from your symptoms.

Treatment for Lyme disease
Continue
  • Intravenous antibiotics can cause various side
    effects, including a lower white blood cell
    count, mild to severe diarrhea, or colonization
    or infection with other antibiotic resistant
    organisms unrelated to Lyme.
  • After treatment, a small number of people still
    experience some symptoms, like muscle aches and
    fatigue. The cause of these continuing symptoms
    is unknown, and treating with more antibiotics
    doesn't help.Some experts believe that certain
    people who get Lyme disease are predisposed to
    develop an autoimmune response that contributes
    to their symptoms. More research is needed.
