Lyme disease



Lyme Disease is caused by borrelia burgdorferi, a pathogen transmitted by the black legged tick. It is treatable but can become chronic lyme disease. A bulls-eye rash can appear at the site of a deer tick bite but can be in different forms while some people never recall having a rash; 30% of lyme patients never get a rash.

Symptoms
The signs and symptoms of lyme disease vary and usually appear in stages.

Early Signs and Symptoms Later Signs and Symptoms Signs and symptoms may also include Less Common Signs and Symptoms
 * Bull's eye rash (Rash can be in other forms and 30% of the time no rash is present.)
 * Flu-like symptoms
 * Erythema migrans
 * Joint pain
 * Neurological problems
 * Nausea and vomiting
 * Diffuse rashes (rather than a single bull's-eye rash commonly associated with Lyme disease) See: Images
 * Heart problems, such as irregular heartbeat.
 * Eye inflammation
 * Liver inflammation (hepatitis).
 * Severe fatigue

Treatment

 * Centers for Disease Control & Prevention (CDC) on Treatment


 * Patients treated with appropriate antibiotics in the early stages of Lyme disease usually recover rapidly and completely. Antibiotics commonly used for oral treatment include doxycycline, amoxicillin, or cefuroxime axetil. Patients with certain neurological or cardiac forms of illness may require intravenous treatment with drugs such as ceftriaxone or penicillin.

Pathobiome Paradigm
Some future research will focus on a spectrum of pathogens instead of a "one pathogen-one disease" vision.

 * BBC1 Lyme Disease Discussion - Some patients have waited up to 30 years for a correct diagnosis. National Health Service (NHS) services have only correctly identified the disease in a quarter of the patients. The blood tests are unreliable and often come back negative. The development of an accurate blood test is in need of research funding.

False positives
Several herpesviruses including varicella zoster virus, cytomegalovirus, Epstein-Barr virus, and HSV-2 may cause false positives on Lyme Disease tests.
