Post-Treatment Lyme Disease Syndromes: 4 Causes of Persistent Symptoms STILL SICK AFTER TREATMENT? FATIGUE, PAIN, OR BRAIN FOG CONTINUE? WHAT IS CAUSING PERSISTENT LYME SYMPTOMS? Post-treatment Lyme disease syndromes describe persistent symptoms that continue after standard antibiotic therapy. Many patients recover—but a significant number remain ill for months or even years. “I finished treatment—but I […]

Borrelia Miyamotoi and Lyme Disease Coinfection: Study of Persistent Symptoms Could Borrelia miyamotoi and Lyme disease coinfection help explain persistent symptoms in some patients? Borrelia miyamotoi (BM) is a tick-borne pathogen transmitted by the same Ixodes ticks that spread Lyme disease. Unlike Lyme disease, erythema migrans rash and joint pain are uncommon in Borrelia miyamotoi

Lyme Disease Treatment: What Works—and What Happens When Symptoms Persist Lyme disease treatment can be straightforward—or unexpectedly complex when symptoms persist. Treatments for Lyme disease vary based on the stage of infection, symptom pattern, duration of illness, and the presence of coinfections. Some patients are diagnosed early and recover quickly. Others are diagnosed later, after

Lyme Disease Prevention: What Works—and What Doesn’t Lyme disease prevention reduces risk—but even careful strategies cannot eliminate exposure. Lyme disease prevention lowers risk—but no single method guarantees protection. Many patients who develop Lyme disease report doing “everything right.” Understanding what works, what doesn’t, and what to do after a tick bite is essential. Key Question:

How Lyme Pathogens Change Tick Behavior and Survival Research suggests that pathogens carried by ticks may alter tick behavior in ways that improve their survival and increase the likelihood of disease transmission. Infections with organisms such as Borrelia, Anaplasma, and Babesia appear capable of manipulating tick biology, potentially increasing the tick’s ability to locate hosts

Lyme Disease Co-Infections: Symptoms, Testing, and Treatment STILL SICK AFTER LYME TREATMENT? CO-INFECTIONS MAY BE THE MISSING PIECE “Why am I not getting better?” For many patients, the answer isn’t Lyme disease alone—it’s co-infections. Quick Answer: Lyme disease co-infections occur when a tick transmits more than one pathogen, often leading to more severe or persistent

What is Lyme disease? Lyme disease is a bacterial infection transmitted to humans through the bite of an infected black-legged tick. The illness is caused by the bacterium Borrelia burgdorferi, a spiral-shaped organism known as a spirochete. The bacterium is typically transmitted by the black-legged tick (Ixodes scapularis), commonly called the deer tick. When an

Why Was the LYMErix Lyme Disease Vaccine Pulled From the Market? A Lyme vaccine once existed. It reduced rashes—but not all disease. So why did it disappear? Interest in a Lyme disease vaccine continues to grow. But many patients are surprised to learn that a vaccine—LYMErix—was already available and then withdrawn from the market. Understanding

When Are Ticks Most Active? Why You Can Be Bitten Any Time of Day When are ticks most active? Many people assume ticks only come out at certain times—but research suggests some ticks may be searching for hosts throughout much of the day. Key Insight: You can be exposed to ticks at any time of
