Long COVID and Lyme Disease: What Patients Need to Know
The Connection Is Real—and I’ve Studied It.
If you’re experiencing persistent symptoms after COVID-19 and have a history of Lyme disease, you’re not imagining things. The overlap between Long COVID and chronic Lyme disease isn’t coincidental—it’s documented.
As a physician who has treated Lyme disease patients for 37 years, an epidemiologist, and a researcher who has published peer-reviewed studies on this exact question, I see the same patterns in both conditions: persistent symptoms that won’t resolve, doctors who dismiss your experience, and a medical system that isn’t equipped to help you.
What My Research Found
In 2023, I published a peer-reviewed study in the journal Antibiotics examining what happens when individuals with a history of Lyme disease contract COVID-19 or receive the COVID-19 vaccine. The study included 889 participants.
The key findings:
One in five Lyme patients who contracted COVID-19 reported Long COVID. This suggests a history of Lyme disease may be a risk factor for developing Long COVID.
Neurological symptoms drove the difference. Patients with both Lyme history and Long COVID experienced significantly worse neurological symptoms compared to those who had COVID without developing Long COVID.
The symptom burden is severe. Using the General Symptom Questionnaire-30 (GSQ-30), we found that individuals with a history of Lyme disease experience high symptom burdens across multiple domains.
Average illness duration: 14.5 years. Participants had been ill far longer than patients in NIH-sponsored trials.

Why Long COVID and Lyme Disease Overlap
The Same Symptom Domains
Both Long COVID and chronic Lyme disease affect similar symptom domains:
- Pain and fatigue
- Neuropsychiatric symptoms: Brain fog, memory issues, concentration problems
- Neurological symptoms
- Viral-like symptoms
Dysautonomia: The Common Thread
Both conditions frequently trigger autonomic nervous system dysfunction. Learn more about Autonomic Dysfunction and Lyme Disease.
Post-Infectious Syndrome as a Framework
Long COVID and Post-Treatment Lyme Disease Syndrome (PTLDS) are both post-infectious syndromes—conditions where symptoms persist long after the initial infection should have resolved.
For a structured clinical overview of ongoing symptoms after Lyme treatment, see Persistent Lyme Disease Symptoms.
Understanding how Lyme disease becomes chronic—and how to prevent it—offers lessons that apply to Long COVID as well. See Preventing Long-Term Lyme Disease.
The Bigger Picture: Post-Infectious Illness
COVID-19 has forced recognition that infections can cause persistent illness that does not show up on standard tests.
For patients navigating recovery from either condition, improvement is possible. See Lyme Disease Recovery and Long-Term Outlook.
