Comprehensive Guide to Lyme Disease: Symptoms, Diagnosis, and Treatment Explained
Lyme disease, first recognized in the town of Old Lyme, Connecticut in 1975, is an infectious disease caused by the bacterium Borrelia burgdorferi, and in rare cases, Borrelia mayonii. This condition is transmitted to humans primarily by the bite of an infected black-legged tick, also known as a deer tick.
Contrary to misconceptions, Lyme disease is not contagious between people. It cannot be transmitted through touching, kissing, having sex, air, food, or water. An infected tick must be attached to the body for at least 36 hours to transmit the bacterium.
The disease is prevalent in certain regions of the United States, including the Northeastern, Mid-Atlantic, and North Central states, as well as on the Pacific Coast. The most common region where Lyme disease is transmitted by infected ticks is the northeastern and upper midwestern states, such as New England, New York, New Jersey, Pennsylvania, Wisconsin, and Minnesota.
Lyme disease may be difficult to diagnose because many of its symptoms are similar to those of other conditions. Symptoms vary depending on the stage of infection. In the early stages, a bull's-eye rash, fever, chills, enlarged lymph nodes, sore throat, vision changes, fatigue, muscle aches, headaches, and other symptoms may be present.
If left untreated, Lyme disease can progress through three stages: Early localized, Early disseminated, and Late disseminated. Late signs and symptoms may include abnormal heart rhythm, neurological conditions, multiple erythema migrans lesions, numbness, tingling, and pain in hands and feet, severe headaches, neck stiffness, meningitis, arthritis, encephalopathy, and other symptoms.
Treatment for Lyme disease in the early stages is a course of oral antibiotics to eliminate the infection. Medications used include doxycycline, amoxicillin, and cefuroxime. If the disease progresses beyond stage 1 or affects the circulatory or central nervous systems, a doctor may prescribe intravenous (IV) antibiotics. Lyme arthritis, a late-stage symptom, is treated with oral antibiotics.
To prevent Lyme disease, protect yourself from ticks by wearing long pants and long-sleeve shirts, using insect repellents, checking yourself for ticks after being outside in areas with brush, long grass, and wood, and removing ticks as soon as possible if they bite. Tick testing for Lyme disease is not recommended by the Centers for Disease Control and Prevention (CDC) due to a lack of stringent quality control standards, potential false negatives or positives, and the fact that treatment should not be delayed.
If you experience any signs or symptoms of Lyme disease, it's best to see a doctor. A healthcare professional will first perform a medical history and physical examination to look for symptoms characteristic of Lyme disease. If you don't have visual symptoms, they'll recommend a serology, which may include the enzyme-linked immunosorbent assay (ELISA) and Western blot blood tests to help detect antibodies.
If you are diagnosed with Lyme disease, the complete course of treatment typically takes 14-28 days. As of 2021, the U.S. states with the highest incidence of Lyme disease include Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, and Wisconsin.
It's crucial to remember that early detection and treatment are key to managing Lyme disease. By understanding the disease, its symptoms, and prevention methods, you can take steps to protect yourself and seek prompt medical attention if needed.
