Public health officials are tracking a concerning spike in emergency room visits related to tick bites across much of the United States. According to the CDC’s Tick Bite Tracker, weekly rates of ER visits for these encounters are currently at their highest levels for this time of year since 2017, with the exception of the South Central region.
As a physician, I often see the anxiety that accompanies a tick discovery. While most tick bites do not result in illness, the current data suggests an increase in exposure that warrants a heightened level of vigilance. This surge comes just as the medical community prepares for Lyme Disease Awareness Month in May, serving as a timely reminder that “tick season” is no longer a brief window in mid-summer, but a prolonged risk period for millions of Americans.
The scale of the issue is significant. Every year, an estimated 31 million people in the U.S. Are bitten by ticks. While many of these cases go unreported, the strain on emergency departments indicates a trend of either increased tick activity or a higher public urgency to seek care. However, one of the most critical takeaways from current CDC guidance is that an emergency room visit is not always the first or best step when a tick is discovered.
Understanding the Risks: Beyond Lyme Disease
While Lyme disease is the most recognized tickborne illness—with approximately 476,000 patients treated for it annually in the U.S.—We see far from the only threat. The CDC is currently warning the public about a spectrum of diseases that vary in severity and symptomology.
Lyme disease, caused by the bacterium Borrelia burgdorferi, is often characterized by the classic “bullseye” rash (erythema migrans), though not every patient develops one. If left untreated, it can spread to the joints, heart, and nervous system. Then there is Rocky Mountain spotted fever (RMSF), a much more acute and potentially fatal illness if not treated early with the correct antibiotics. RMSF typically presents with high fever, severe headache, and a characteristic spotted rash on the wrists and ankles.
Perhaps most unusual is alpha-gal syndrome, a serious allergic reaction to red meat (mammals) that can be triggered by the bite of a Lone Star tick. Unlike the bacterial infections mentioned above, alpha-gal is an immune response that can lead to anaphylaxis after eating beef, pork, or lamb, fundamentally altering a person’s diet and medical needs.
| Disease | Primary Vector | Key Warning Sign | Urgency |
|---|---|---|---|
| Lyme Disease | Black-legged (Deer) Tick | Bullseye rash, joint pain | High (Early treatment is key) |
| RMSF | American Dog Tick | High fever, spotted rash | Critical (Emergency care needed) |
| Alpha-gal | Lone Star Tick | Hives/anaphylaxis after red meat | High (Long-term dietary change) |
The 24-Hour Window and Proper Removal
One of the most common misconceptions I encounter in clinical practice is the belief that you must wait for a doctor to remove a tick to ensure it is “done right” or to save the tick for testing. In reality, waiting to get to an emergency room can be counterproductive.
The CDC emphasizes that removing an attached tick as soon as possible is the best form of protection. Specifically, removing a tick within 24 hours of attachment can significantly reduce the risk of contracting Lyme disease, as the bacteria typically require a longer period of attachment to migrate from the tick’s midgut to the human host.
To remove a tick safely, 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, which can cause the mouthparts to break off and remain in the skin. Once removed, clean the bite area and your hands with rubbing alcohol or soap and water. There is no clinical evidence to support “home remedies” like using nail polish, petroleum jelly, or heat to “suffocate” the tick; these methods can actually increase the risk of the tick regurgitating pathogens into the bloodstream.
Proactive Prevention Strategies
Preventing the bite is always more effective than treating the disease. As Dr. Alison Hinckley, an epidemiologist and Lyme disease expert with the CDC, notes, “these tiny biters can make you seriously sick,” but the tools for prevention are readily available and highly effective.
For those spending time in wooded or grassy areas, the CDC recommends a two-pronged approach to chemical protection:
- On the Skin: Use EPA-registered insect repellents containing DEET, picaridin, or IR3535. These create a chemical barrier that discourages ticks from attaching.
- On the Clothing: Treat gear and clothing with permethrin. Unlike skin repellents, permethrin binds to the fabric and actually kills ticks on contact. It remains effective through several wash cycles.
Beyond chemicals, behavioral changes are essential. Wearing long sleeves and tucking pants into socks creates a physical barrier that forces ticks to crawl on the outside of the clothing, making them easier to spot during a “tick check.” A thorough full-body check—including the scalp, armpits, and behind the knees—should be performed immediately after returning indoors.
When to Seek Medical Attention
While not every bite requires a trip to the clinic, certain “red flags” necessitate immediate medical intervention. If you develop a fever, chills, fatigue, or a rash in the days or weeks following a tick bite or exposure to a tick-heavy area, you should contact a healthcare provider promptly.

When speaking with your doctor, be as specific as possible about where you were (e.g., a specific hiking trail or region) and when the bite occurred. This geographic context is vital for physicians, as different regions harbor different tick species and different pathogens.

As we move into May, the CDC will increase its public outreach for Lyme Disease Awareness Month, providing updated resources and regional risk maps. Public health officials will continue to monitor the Tick Bite Tracker to determine if this current surge is a temporary anomaly or part of a larger shift in tick populations due to changing environmental conditions.
