It is caused by gram-negative \u003cem\u003eBorrelia\u003c\/em\u003e spirochetes, spiral-shaped bacteria that are carried by certain species of ticks. In European countries, the disease is most often caused by the species \u003cem\u003eBorrelia afzelii\u003c\/em\u003e or \u003cem\u003eBorrelia garinii\u003c\/em\u003e, and less frequently by \u003cem\u003eBorrelia burgdorferi\u003c\/em\u003e. On the North American continent, \u003cem\u003eBorrelia burgdorferi\u003c\/em\u003e is the most common genospecies responsible for the disease.\u003c\/p\u003e\n\n\u003cp\u003eThe type of tick that transmits the bacteria also varies by region. In Europe, the disease is mainly caused by the bite of \u003cem\u003eIxodes ricinus\u003c\/em\u003e and \u003cem\u003eIxodes persulcatus\u003c\/em\u003e ticks, while in the United States, \u003cem\u003eIxodes scapularis\u003c\/em\u003e and \u003cem\u003eIxodes pacificus\u003c\/em\u003e are the primary vectors. The disease is most prevalent in North America, Central and Northern Europe, and Northern Asia.\u003c\/p\u003e\n\n\u003cp\u003eOne of the most important things to understand about Lyme disease is the timing of transmission. When a tick carrying \u003cem\u003eBorrelia afzelii\u003c\/em\u003e bites, infection can occur in less than 24 hours. For \u003cem\u003eBorrelia burgdorferi\u003c\/em\u003e carried by \u003cem\u003eIxodes scapularis\u003c\/em\u003e ticks, transmission typically occurs after 36 hours of attachment. Interestingly, a large proportion of infections are transmitted by tick nymphs (immature ticks), because they are smaller than mature adults and much more difficult to spot on the skin surface. The risk of transmission increases directly with the length of time an infected tick remains attached to the skin.\u003c\/p\u003e\n\n\u003cp\u003eThe hallmark first sign of infection, called erythema migrans, usually appears at the site of the tick bite within 3 to 30 days. Tick bites occur most often in late spring and early summer, when tick populations surge and people spend more time outdoors. Ticks are commonly found in forests, parks, and meadows, in both urban and suburban areas.\u003c\/p\u003e\n\n\u003ch2 id=\"review-methods\"\u003eHow This Review Was Conducted\u003c\/h2\u003e\n\n\u003cp\u003eThe authors of this literature review searched the PubMed database using combinations of key words, including \"Lyme disease,\" \"treatment,\" and \"prevention.\" They focused on the most current evidence, with scientific articles published between 2016 and 2024 accounting for 92% of all references cited in the review.\u003c\/p\u003e\n\n\u003cp\u003eInclusion criteria were rigorous.

This is a gradually enlarging, ring-shaped skin lesion with central clearing and a red border, often described as a \"bull's-eye\" rash. The lesion appears between 3 and 30 days after a tick bite, most commonly after about 7 days. In addition to the rash, early localized Lyme disease can include flu-like symptoms and, less commonly, a Lyme lymphocytoma, which is a painless nodule that may appear in the earlobe or scrotal region.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe early disseminated stage\u003c\/strong\u003e develops weeks to a few months after infection.

It is important to note that very broad-spectrum antibiotics such as fluoroquinolones or aminoglycosides are \u003cstrong\u003enot recommended\u003c\/strong\u003e for Lyme disease.\u003c\/p\u003e\n\n\u003cp\u003eThe duration of antibiotic treatment should usually be limited to 28 days. Longer therapy has not been shown to be beneficial and may only increase the risk of side effects. For flu-like symptoms, non-steroidal anti-inflammatory drugs (NSAIDs) are recommended. In cases of large amounts of joint effusion (fluid accumulation in a joint), a puncture may be performed for decompression, which helps reduce pain.\u003c\/p\u003e\n\n\u003cp\u003eA key trend highlighted in this review is that recent evidence supports \u003cstrong\u003eshorter courses of antibiotic therapy\u003c\/strong\u003e, showing similar cure rates for patients receiving both long and short treatment. This matters in the context of finding the shortest effective treatment period, reducing antibiotic resistance, and minimizing the adverse effects of prolonged antibiotic exposure.\u003c\/p\u003e\n\n\u003ch2 id=\"erythema-migrans\"\u003eErythema Migrans (The Hallmark Rash)\u003c\/h2\u003e\n\n\u003cp\u003eThe appearance of erythema migrans after a tick bite undoubtedly requires treatment without expanding the diagnostic workup. Because the rash appears within 30 days after the bite, patients are advised to observe the bite site during this entire period. Different medical societies have issued slightly different but broadly similar guidelines for treating this early manifestation.\u003c\/p\u003e\n\n\u003cp\u003eAccording to the National Institute for Health and Clinical Excellence (NICE) from the UK, doxycycline is the treatment of choice for 21 days, at a dose of 200 mg once a day, or in two divided doses of 100 mg each. In contrast, the combined guidelines from the Infectious Diseases Society of America (IDSA), the American Academy of Neurology (AAN), and the American College of Rheumatology (ACR) indicate doxycycline for 10 days, or amoxicillin 500 mg three times a day for 14 days, or cefuroxime axetil 500 mg twice daily as first-line treatment.\u003c\/p\u003e\n\n\u003cp\u003ePolish guidelines from the Society of Epidemiologists and Physicians of Infectious Diseases (PTEiLChZ) recommend doxycycline for 7 to 21 days, or amoxicillin or cefuroxime axetil for 14 to 21 days. The shorter doxycycline course reflects a study showing that 7-day antibiotic therapy had comparable cure rates to 2-week therapy, while allowing patients less time exposed to the medication.\u003c\/p\u003e\n\n\u003cp\u003eSpanish societies, including the Society of Infectious Diseases and Clinical Microbiology (SEIMC), Society of Neurology (SEN), Society of Immunology (SEI), Spanish Society of Paediatric Infectology (SEIP), Society of Rheumatology (SER), and the Academy of Dermatology and Venereology (AEDV), jointly recommend doxycycline first for 10 to 21 days.

First, most cases of Lyme disease can be effectively treated with oral antibiotics, and the duration of treatment is now recognized to be shorter than previously thought — usually no more than 28 days, and often just 7 to 21 days for early localized disease. Second, early recognition of erythema migrans is critical: if you see a bull's-eye rash after a tick bite, seek medical attention without delay.\u003c\/p\u003e\n\n\u003cp\u003eFor those who find an attached tick, proper removal is essential. Do not squeeze or lubricate the tick, as this can cause it to regurgitate bacteria into your bloodstream. Instead, use fine-tipped tweezers to grasp the tick close to the skin and pull upward with steady, even pressure. If you are in a high-risk situation, ask your doctor whether a single dose of doxycycline within 72 hours is appropriate for you.\u003c\/p\u003e\n\n\u003cp\u003eThe review also emphasizes that there is no role for prolonged or repeated antibiotic courses in most cases of Lyme disease.

After removing it, observe the bite site for 30 days and see a doctor if a rash develops.\u003c\/p\u003e\n\u003ch3\u003eWhat does the Lyme disease rash look like and when does it appear?\u003c\/h3\u003e\n\u003cp\u003eThe hallmark rash, erythema migrans, is a gradually enlarging ring-shaped lesion with central clearing and a red border, often called a bull's-eye rash. It usually appears at the tick bite site within 3 to 30 days, most commonly after about 7 days. If you see it, seek medical attention promptly.\u003c\/p\u003e\n\u003ch3\u003eCan a single dose of doxycycline prevent Lyme disease after a tick bite?\u003c\/h3\u003e\n\u003cp\u003eYes. Guidelines recommend a single 200 mg dose of doxycycline taken within 72 hours of tick exposure for people with multiple tick bites. In one randomized trial, this lowered risk by 67%, and a meta-analysis of 4 studies found protection in 87% of cases. Ask your doctor whether it is right for you.\u003c\/p\u003e\n\u003ch3\u003eHow long is antibiotic treatment for early localized Lyme disease?\u003c\/h3\u003e\n\u003cp\u003eTreatment for erythema migrans typically lasts 7 to 21 days, depending on the guideline. Doxycycline is commonly used for 10 to 21 days, or amoxicillin or cefuroxime for 14 to 21 days. Total antibiotic treatment for Lyme disease is usually no longer than 28 days; longer courses have not been shown to help.\u003c\/p\u003e\n\u003ch3\u003eWhat symptoms may appear in later or disseminated Lyme disease?\u003c\/h3\u003e\n\u003cp\u003eWeeks to months after infection, late or disseminated Lyme disease can cause joint pain and swelling (arthritis), facial nerve palsy, palpitations or irregular heartbeat (carditis), and neurological symptoms like meningitis or radiculopathy. If you have these symptoms after a tick bite, inform your healthcare provider about the exposure and ask about testing.\u003c\/p\u003e\n\u003c!-- ddn:faq:end --\u003e\n\n\u003ch2 id=\"source\"\u003eSource Information\u003c\/h2\u003e\n\n\u003cp\u003eThis patient-friendly article is based on the following peer-reviewed research:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOriginal title:\u003c\/strong\u003e Current methods of treatment and prevention of Lyme borreliosis – literature review\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAuthors:\u003c\/strong\u003e Grzegorz Pyc, Jan Kowalewski, Aleksandra Dąbrowska, Damian Bęben, Maria Dudzik, Kornel Majewski, Kinga Pakos, Kamila Durmała, Urszula Sielicka, Jakub Mączka\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJournal:\u003c\/strong\u003e Journal of Pre-Clinical and Clinical Research, 2024, Vol 18, No 3, pages 276–281\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDOI:\u003c\/strong\u003e 10.26444\/jpccr\/192029\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePublication dates:\u003c\/strong\u003e Received June 5, 2024; accepted August 5, 2024; first published September 9, 2024\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAuthor affiliations:\u003c\/strong\u003e Medical University institutions in Szczecin, Poznań, and Wrocław, Poland, including the Department of Nephrology, Transplantology and Internal Diseases at Pomeranian Medical University, the Clinical Department of Cardiology and Internal Diseases at the University Clinical Hospital in Poznań, and military clinical hospitals in Szczecin and Wrocław.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThis patient-friendly article is based on peer-reviewed research.
