Some sources suggest this duration may need to be 36 to 48 hours or longer before the disease-causing bacteria can be transmitted. If the tick is removed within 24 hours of attachment, the risk of transmitting the infection is significantly reduced. It is important to know that symptoms of Lyme disease may not appear until 3 to 30 days or more after the bite of an infected tick [\[1\]](). ## How does Lyme disease spread? Lyme disease is a bacterial infection transmitted to humans through the bite of an infected tick. In the United States, the bacteria usually responsible is *Borrelia burgdorferi*. These ticks, known as deer ticks or black-legged ticks, are often found in grassy, bushy, and wooded areas. Ticks can attach to any part of the body, but they are often found in hard-to-see areas such as the groin, armpits, and scalp [\[1\]](). Most tick bites occur during the warmer months, from April to September, when ticks are most active and people spend more time outdoors. However, bites can occur at other times of the year, especially if temperatures are higher than normal. A mild winter may lead to tick activity earlier than usual [\[1\]](). ## Early and late symptoms of Lyme disease Early symptoms of Lyme disease typically appear between 3 to 30 days after the bite of an infected tick and may include [\[1\]](): - A distinctive red rash called erythema migrans, which affects most people with Lyme disease. The rash expands over several days and may feel warm, usually without being painful or itchy. It may fade in parts to form a "bull's-eye" appearance [\[1\]](). - Fever and chills. - Headache. - Fatigue. - Muscle and joint aches. - Swollen lymph nodes. If the infection is not treated, it can spread to the joints, heart, and nervous system, leading to late symptoms such as [\[1\]](): - Severe headache and neck stiffness. - Additional erythema migrans rashes in other areas of the body. - Facial palsy, which causes weakness in facial muscles. - Arthritis with severe joint pain and swelling, particularly in the knees and other large joints. - Intermittent pain in tendons, muscles, joints, and bones. - Heart palpitations or an irregular heartbeat. - Episodes of dizziness or shortness of breath. - Inflammation of the brain and spinal cord. - Nerve pain, or shooting pains, numbness, or tingling in the hands or feet. ## What to do if you are bitten by a tick If you find a tick attached to your skin, it is important to remove it as soon as possible to reduce the risk of transmitting Lyme disease. Use fine-tipped tweezers to grasp the tick as close to the skin's surface as possible. Pull upward with steady, even pressure; avoid twisting or jerking the tick. The goal is to remove the entire tick, including the mouthparts embedded under the skin. After removal, clean the bite area and your hands thoroughly with soap and water or rubbing alcohol. Do not crush the tick with your fingers [\[2\]](). After removing the tick, monitor for the development of any symptoms of Lyme disease over the following weeks. If a distinctive rash (erythema migrans) or any of the other mentioned symptoms appear, you should consult a doctor immediately. Early diagnosis and antibiotic treatment can help ensure a quick and full recovery [\[1\]]().

Follow the instructions on the label [\[1\]](). - Treat your clothing and gear with products containing 0.5% permethrin [\[1\]](). - Wear light-colored protective clothing to make it easier to see any ticks that might attach to you. It is preferable to wear long-sleeved shirts and long pants, tucking the shirt into the pants and the pants into socks [\[1\]](). - Check yourself, your children, and your pets daily for ticks after spending time outdoors [\[1\]](). - Shower and wash and dry your clothes on high heat after returning from outdoor areas [\[1\]](). ## Medical references - [Lyme Disease]() - [Ticks and Lyme Disease: Symptoms, Treatment, and Prevention]() General health education; not a substitute for individualized clinical assessment.
