  • Lyme disease
Clinical Information
  • An infectious disease caused by a spirochete, borrelia burgdorferi, which is transmitted chiefly by ixodes dammini (see ixodes) and pacificus ticks in the United States and ixodes ricinis (see ixodes) in europe. It is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations. The disease was formerly known as lyme arthritis and first discovered at old lyme, connecticut.
  • An infectious disease caused by the spirochete borrelia burgdorferi. Early manifestations of infection may include fever, headache, fatigue, depression, and a characteristic skin rash called erythema migrans. Left untreated, late manifestations involving the joints, heart, and nervous system can occur.
  • Lyme disease is a bacterial infection you get from the bite of an infected tick. The first symptom is usually a rash, which may look like a bull's eye. As the infection spreads, you may have
    • a fever
    • a headache
    • muscle and joint aches
    • a stiff neck
    • fatigue
    lyme disease can be hard to diagnose because you may not have noticed a tick bite. Also, many of its symptoms are like those of the flu and other diseases. In the early stages, your health care provider will look at your symptoms and medical history, to figure out whether you have lyme disease. Lab tests may help at this stage, but may not always give a clear answer. In the later stages of the disease, a different lab test can confirm whether you have it.antibiotics can cure most cases of lyme disease. The sooner treatment begins, the quicker and more complete the recovery.after treatment, some patients may still have muscle or joint aches and nervous system symptoms. This is called post-lyme disease syndrome (plds). Long-term antibiotics have not been shown to help with plds. However, there are ways to help with the symptoms of plds, and most patients do get better with time.
  • Recurrent multisystemic infectious disease caused by a spirochete, borrelia burgdorferi, which is transmitted chiefly by ixodes ticks; it is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations.
