Long COVID clinic marketing: honest claims

Long COVID clinics and post-viral programs are run by primary care practices, pulmonology and cardiology groups, rehabilitation services, health systems and integrative or functional medicine practices. The patients they serve have been ill for months, have seen several clinicians and are searching hard for anything that helps. That makes honest marketing both more important and easier to get wrong. CDC and NIH say there is no laboratory test that can confirm long COVID and no treatment approved specifically for it. A clinic can still offer real value: a full evaluation, symptom-focused care, rehabilitation planned around post-exertional malaise and help with daily life. This guide covers how to say that without promising a cure, a protocol or a test that does not exist.

Two related topics have their own guides and are not repeated here. Respiratory testing, sleep and lung disease claims are covered in our pulmonology practice marketing guide. Root-cause, lab panel and supplement wording for functional medicine is covered in our functional medicine practice marketing guide. This guide covers what is specific to long COVID and post-viral care.

This is general information, not legal or medical advice. Sources cited were checked on October 30, 2026: the CDC pages Long COVID Basics (May 6, 2026), Living With Long COVID (March 9, 2026), Clinical Overview of Long COVID (March 9, 2026) and Clinical Guidance for Long COVID (March 9, 2026), the NIH RECOVER Initiative page What is Long COVID, the HHS OCR and DOJ Guidance on Long COVID as a Disability Under the ADA, Section 504, and Section 1557 (July 26, 2021), the FTC page of coronavirus warning letters to companies, 15 U.S.C. 45 and 52, the FTC Health Products Compliance Guidance, 16 CFR 255.2, 45 CFR 164.508 and the Google Ads restricted targeting policy.

What CDC and NIH say about long COVID

CDC’s page Long COVID Basics defines long COVID as a chronic condition that occurs after SARS-CoV-2 infection and is present for at least 3 months. It says long COVID is not one illness, that symptoms and conditions can emerge, persist, resolve and reemerge over weeks, months and even years, and that they can range from mild to severe and can in some cases result in a disability. It says anyone who had the infection can experience long COVID, including children, and that some people who later develop it do not know when they were infected.

Two statements on that page shape every claim a clinic makes. CDC says there is no approved laboratory test that can determine if a person’s symptoms or conditions are due to long COVID, and that a positive SARS-CoV-2 test is not required for a diagnosis. It also says living with long COVID can be difficult and isolating, especially when there are no approved tests and no approved treatments. The NIH RECOVER Initiative page What is Long COVID says there is no specific test or measurement that can diagnose long COVID at this time, and that there are no FDA-approved treatments designed specifically for long COVID. It says RECOVER researchers are studying the safety and effectiveness of different treatments, including medicines, devices, exercises and changes in behavior.

CDC’s Clinical Overview of Long COVID calls it an infection-associated chronic condition that affects one or more organ systems, says it is heterogeneous and may be attributed to different underlying processes, and lists several possible causes still under study. Its Clinical Guidance for Long COVID says the goal of medical management for the large majority of patients is to optimize function and quality of life through established symptom management approaches, such as focusing on the symptoms the patient identifies as the heaviest burden, a comprehensive rehabilitation plan, management of underlying conditions and symptom diaries. It says treatment should be tailored to the patient’s specific symptoms or conditions, and that clinicians should set achievable goals through shared decision-making.

A clinic page that matches those sources describes an evaluation and a management plan, not a diagnosis by a special test and not a treatment that ends the illness.

Claims that need rewriting

Under 15 U.S.C. 45, deceptive acts or practices in commerce are unlawful, and 15 U.S.C. 52 prohibits false advertisements likely to induce the purchase of drugs, devices or services. The FTC staff Health Products Compliance Guidance says claims about the health benefits or safety of health-related products require competent and reliable scientific evidence. COVID claims have drawn this kind of attention before. The FTC page of coronavirus warning letters to companies lists letters the FTC sent to companies allegedly selling unapproved products with deceptive or scientifically unsupported claims about their ability to treat or cure COVID-19. Those letters addressed claims about the infection itself, and the page records the FTC’s allegations, not findings. The same law applies to claims about long COVID. Our guide to advertising during an outbreak or flu season describes FDA and FTC warning letters sent to practices over COVID-19 claims.

Phrases that need rewriting:

“We cure long COVID” or “reverse long COVID”. CDC says there are no approved treatments, and NIH says treatments are still being studied. Write “We evaluate your symptoms and build a care plan aimed at improving function and quality of life.”
“Our proven long COVID protocol” or “the treatment that works”. NIH lists treatments under study, not a proven protocol. Describe what the clinic does: evaluation, symptom management, rehabilitation planning and referrals.
“The test that confirms long COVID” or “blood work that proves your symptoms are real”. CDC and NIH say no laboratory test can confirm it. Describe tests as part of an evaluation that looks for other causes and tracks specific problems.
“Clear the virus” or “detox the spike protein”. These claims describe a mechanism and a result that the federal sources above do not support.
“Back to normal in weeks” or any timeline. CDC says symptoms can improve, worsen or reemerge over months and years.
“Every patient improves” or a before and after story presented as what readers will get. See the section on stories below.

Post-exertional malaise and rehab wording

Rehabilitation is part of what CDC describes, but how a clinic talks about exercise matters. CDC’s clinical guidance describes post-exertional malaise, or PEM, as the worsening of symptoms after even minor physical or mental exertion, and says the worsening can come 12 to 48 hours after activity and last for days or even weeks. RECOVER lists feeling worse after being active among the symptoms people report. CDC also says some people with long COVID have symptoms similar to those of myalgic encephalomyelitis/chronic fatigue syndrome, and that patients may benefit from symptom management approaches used for that condition.

For a clinic, that means:

Do not market “push through it”, “train your way back” or a fixed exercise program as the answer for every patient.
Say that activity plans are set after an evaluation, adjusted to how each person responds, and that the team asks about symptoms in the days after activity.
Describe a rehabilitation plan as one part of care, not a cure.
Make intake and follow-up possible without long in-person visits where the clinic can offer that, since the visit itself can be exertion.

Physical, occupational and cardiopulmonary rehabilitation programs should also follow our physical therapy marketing guide and our cardiac and pulmonary rehab marketing guide.

Supplements, IV drips and treatments under study

Long COVID patients are offered supplements, infusions, devices and medicines used outside their labeled use. A clinic should not advertise any of these as a long COVID treatment. NIH says there are no FDA-approved treatments designed specifically for long COVID, and the FTC guidance requires competent and reliable scientific evidence for health benefit claims. Keep product, drug and device names out of ads and service pages, and leave treatment choices to the clinician’s conversation with the patient.

If a clinic takes part in a research study, it can say so and link the study’s own listing, but it should not imply that NIH or any agency endorses the clinic or the care it sells outside the study. Clinics that sell supplements or infusions should also read our guides to selling supplements in a medical practice and IV therapy clinic marketing, and integrative practices our guide to integrative medicine marketing claims.

Writing for patients who feel dismissed

CDC says difficult-to-explain symptoms may be misunderstood by healthcare providers, which can delay diagnosis and care, and its clinical guidance tells providers to validate patients’ symptoms and recognize the impact of illness on quality of life. A clinic can say plainly that it takes long-lasting symptoms seriously. CDC’s basics page says blood tests, chest X-rays and electrocardiograms may be normal in someone with long COVID.

What a clinic should not do is turn that into fear or blame. Avoid copy that says other doctors are wrong, that the reader’s condition will get worse without the clinic’s program, or that only this clinic understands long COVID. CDC’s guidance says primary care providers can manage long COVID using patient-centered approaches, so a clinic page can explain what it adds, such as longer visits or a coordinated team, without running down other care.

RECOVER lists depression, anxiety and mood changes among reported symptoms. Pages that discuss mood or mental health should carry a plain line: “If you are in crisis or thinking about harming yourself, call or text 988. For a medical emergency, call 911.”

Access, disability and intake

The HHS Office for Civil Rights and the Department of Justice issued guidance on long COVID as a disability under the ADA, Section 504, and Section 1557. It says long COVID can be a disability under those laws if it substantially limits one or more major life activities, that an individualized assessment is necessary, and that people whose long COVID qualifies as a disability are entitled to the same protections from discrimination as any other person with a disability, including reasonable modifications. CDC’s page Living With Long COVID says the same: long COVID is a recognized condition that may result in a disability under the ADA.

A clinic serving this group should build its website and intake with that in mind: forms that can be saved and finished later, plain language, options to call or message instead of filling long forms, and a clear way to ask for a modification. Our guides to website accessibility for medical practices and Section 1557 website notices cover the website side.

Do not promise help with disability benefits or paperwork outcomes. If the clinic completes forms for employers, schools or benefit programs, describe that service and its fees, and say the decision belongs to the agency or employer.

Patient stories, tracking and ads

Long COVID patient stories can be powerful, and they can mislead. Under 16 CFR 255.2, an advertisement that uses a consumer endorsement about a key attribute of a service is likely to be read as representing that the endorser’s experience is representative, unless the advertiser has substantiation for that or clearly and conspicuously discloses what people can generally expect. CDC says symptoms vary widely and can improve, worsen or reemerge, so a recovery story implies a result the clinic cannot promise. If you use stories, keep them about the experience of care, get a signed authorization under 45 CFR 164.508 where the practice is a covered entity, and say that results vary.

Symptom checklists, intake questionnaires and appointment requests for a long COVID clinic are health information. Keep them out of advertising and analytics tools unless you have checked what each tool receives and what your agreements with it cover, as our guide to tracking pixels on practice websites explains.

For ads, the Google Ads restricted targeting policy for personalized advertising lists health among its sensitive interest categories, so audiences cannot be built around a person’s condition. Use keyword and location targeting with an honest landing page. Our healthcare ad policy basics guide covers the wider policy, and our telehealth marketing guide covers virtual visits.

Illustration: two ads for the same clinic

Illustration: an ad reads “Long COVID? Our proven protocol clears lingering virus and gets you back to normal in 6 weeks. Lab test confirms your diagnosis. Push past the fatigue with our recovery bootcamp.” It promises a protocol and a timeline the federal sources do not support, claims a confirming test that CDC and NIH say does not exist, and markets exertion to people who may have post-exertional malaise.

Illustration: a second ad for the same clinic reads “Long COVID care at [Practice name]. A full evaluation, a care plan built around your symptoms and activity plans adjusted to how you respond. Led by a [license type]. Virtual follow-up available.” The landing page links to CDC and NIH, says there is no approved test or treatment specifically for long COVID, explains how to ask for a modification, and carries the 988 and 911 line on pages about mood.

Checklist before a long COVID campaign goes live

No page promises a cure, reversal, a proven protocol or a recovery timeline.
No page claims a test that confirms or proves long COVID; testing is described as part of an evaluation.
Pages say there are no approved tests or treatments specifically for long COVID, with links to CDC and NIH.
No supplement, infusion, drug or device is advertised as a long COVID treatment, and no product names appear in ads.
Exercise and rehab wording reflects post-exertional malaise; no “push through it” copy.
Copy does not blame other clinicians or use fear about worsening.
Pages about mood or mental health carry the 988 and 911 line.
Website and intake allow saving progress, phone or message options and a clear way to ask for a modification.
Patient stories describe the experience of care, have signed authorization and say results vary.
Symptom forms stay out of ad and analytics tools, and ads do not target by health condition.

How we help

We build websites, local search, Google Ads and AI front desk tools for independent practices and health businesses. For a long COVID or post-viral clinic, that means service pages that describe evaluation and care honestly with links to CDC and NIH, ads that do not promise a cure or a timeline, and intake forms that are easy to finish and keep symptom details away from tracking tools. We do not decide which treatments are offered or how care is delivered; your clinicians, your counsel and your state’s rules do. Our tools are built with HIPAA in mind. We confirm in writing what a BAA covers before any patient information flows through a tool, and if it is not covered, we do not route patient information through it. We are not a healthcare provider and we do not give legal or medical advice. We do not sell lead lists and we do not pay for referrals. For the wider rules, see our healthcare marketing rules hub.

Can a clinic say it treats long COVID?

A clinic can say it evaluates and manages long COVID symptoms. CDC says there are no approved treatments for long COVID, and NIH says there are no FDA-approved treatments designed specifically for it, so avoid words like cure, reverse or proven protocol.

Can we advertise a test that diagnoses long COVID?

No. CDC says there is no approved laboratory test that can determine if symptoms are due to long COVID, and NIH says there is no specific test or measurement that can diagnose it. Describe testing as part of an evaluation.

How should we talk about exercise and rehabilitation?

CDC describes post-exertional malaise as symptoms worsening after even minor exertion, with the worsening coming 12 to 48 hours later and lasting days or weeks. Say activity plans are set after evaluation and adjusted to how each person responds, and avoid push through it messaging.

Can we sell supplements or IV drips for long COVID?

Do not advertise any product as a long COVID treatment. The FTC requires competent and reliable scientific evidence for health benefit claims, and NIH says treatments are still being studied.

Is long COVID a disability?

HHS OCR and DOJ guidance says long COVID can be a disability under the ADA, Section 504 and Section 1557 if it substantially limits one or more major life activities, based on an individualized assessment. Build intake and the website so patients can ask for modifications.

Can we use recovery stories in ads?

Under 16 CFR 255.2, a story about a key result is read as representative unless you can back that up or clearly say what people can generally expect. Keep stories about the experience of care, get written authorization and say results vary.
