As the summer season approaches, it brings with it the opportunity to spend more leisure time outdoors, whether relaxing on your lawn or exploring nature trails. However, it’s important to remember that we’re not the only ones eagerly anticipating the warm days ahead. Ticks, small insects ranging in size from poppy to sesame seeds, are most active from April through September. Unlike most insects, ticks pose a significant threat as they are responsible for spreading Lyme disease, particularly in the Northeast, mid-Atlantic, and upper Midwest regions of the United States. Lyme disease is the most common illness transmitted by biting insects and is caused by a parasite.
While Lyme disease can be treated with antibiotics if caught early, it can lead to more severe symptoms affecting the joints, heart, and nervous system if left untreated. Therefore, it is essential to recognize the early signs of Lyme disease or take precautions to prevent it altogether. In this article, infectious disease experts share the most common early symptoms of Lyme disease and provide tips on how to avoid being bitten by ticks in the first place.
According to Dr. Tammy Lundstrom, an infectious disease specialist, and Dr. Sarah Park, an infectious disease clinician, the primary early sign of Lyme disease is a rash called “erythema migrans,” which resembles a bullseye or target. However, this rash may be faint and may not be visible in 20-30% of cases, especially on darker skin tones. The rash typically appears within three to 30 days after a tick bite.
Other flu-like symptoms such as achy joints, chills, fever, and headache can also indicate Lyme disease. These symptoms can often be mistaken for common viral infections like the flu or a cold. However, if you’ve been exposed to ticks in areas such as brush, woodsy environments, or tall grass, and experience these symptoms within three to seven days, it’s crucial to consult a medical professional for further evaluation.
Sudden fatigue is another early sign of Lyme disease that is often disregarded as normal tiredness from lack of sleep or regular daily activities. It’s important to recognize that fatigue could be a symptom and seek medical advice if it persists.
In addition to the bullseye rash and flu-like symptoms, other skin manifestations like hives or sunburn-like discomfort can also be early signs of Lyme disease.
Preventing Lyme disease is the best approach, and there are several measures you can take. Since ticks in the nymph stage are the main culprits, it’s important to thoroughly check for ticks after outdoor activities, even in skin folds and hair. Wearing long pants and long-sleeved shirts while hiking is recommended, along with treating clothing with the insect repellent permethrin or using pretreated hiking gear. EPA-registered insect repellents containing DEET are also effective. Walking in the center of trails and examining your skin and clothing carefully are essential practices.
If you prefer DEET-free alternatives, insect repellents containing picaridin, IR3535, Oil of Lemon Eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone are suitable options.
Regular tick checks are crucial, especially if you live in an area with a higher prevalence of Lyme disease. If you find a tick attached to your body, it’s important to remove it promptly. It typically takes 36 to 48 hours for a tick to transmit Lyme disease, so early removal is key to prevention.
While a Lyme disease vaccine may be developed in the future, it’s essential to remain vigilant and take necessary precautions. Familiarize yourself with the early signs of Lyme disease, wear protective clothing, use insect repellent, and conduct regular tick checks. By following these guidelines, you can enjoy your summer activities without the worry of Lyme disease.
