Disclosure

Affiliate & Advertising Disclosure

FluTrack is free to use. This page explains, plainly, how the site pays for itself — through display advertising and clearly labeled affiliate links — and, just as importantly, the firewall that keeps that money from ever touching the threat level we report.

Last updated: July 2026

The short version

FluTrack is supported by display advertising and by affiliate links. If you click certain links and buy something, we may earn a commission — at no extra cost to you. None of that changes the threat level. The index is computed from public-domain CDC data alone, and it is never for sale, sponsorship, or promotion.

How FluTrack is funded

FluTrack turns the CDC's weekly respiratory surveillance into a plain-English threat level, free of charge and without a login. Keeping a free utility online still costs money, and we fund it in two ordinary ways: display advertising served on the site, and affiliate links to products and services a reader might reasonably look for after checking respiratory activity. We disclose both here so you always know how the site earns, and can weigh what you read accordingly.

What an affiliate link is

An affiliate link is a normal link that carries a referral code. If you follow one of these links and go on to make a purchase, the merchant may pay FluTrack a small commission for the referral. The price you pay is exactly the same whether you use our link or navigate to the merchant directly — the commission comes out of the merchant's margin, at no extra cost to you.

Where they appear, affiliate links point to categories that relate to respiratory-illness season — for example:

  • Telehealth services, for people who want to speak with a clinician;
  • At-home test kits for flu, COVID-19 and other respiratory illnesses;
  • Air purifiers, filters and indoor-air products; and
  • Masks and other personal protective equipment (PPE).

Listing a category is not a recommendation that you buy anything in it. FluTrack describes what the CDC's data shows; it does not tell you what to purchase, and the presence of an affiliate link says nothing about whether a product is right for you.

Advertising and affiliate revenue never influence the data

This is the part that matters most, so we will be unambiguous about it. No advertiser and no affiliate partner can influence the threat level, the trend, or anything else FluTrack reports about respiratory activity. The index is computed purely from public-domain CDC surveillance signals — emergency-department visits, laboratory test positivity and wastewater viral activity — using the same published method for every state, regardless of who advertises or which links a page carries.

The threat level is not for sale

A state's reading is never sold, sponsored, promoted, or adjusted for any commercial reason. No payment can raise or lower a threat level, feature a state, or change how the data is described. If it could, the number would be worthless — so it cannot.

Advertising is kept separate from the data

Advertising and editorial data live in separate lanes. Display ads are supplied by third-party advertising partners and are presented as advertising — distinct from the CDC-derived threat level, pathogen breakdown, and underlying signals, which are ours and are never sponsored. An advertiser's presence on a page has no bearing on the numbers shown beside it. We do not let sponsors review the data before it publishes, and we do not shade our description of the CDC's figures to suit anyone paying to reach our readers. How the index is built is documented in full on our methodology and data sources pages, so anyone can check it against the public feeds.

How we label ads and affiliate links

We aim to make the commercial parts of the page obvious rather than disguised. Advertising is presented as advertising. Where a link is an affiliate or sponsored link, it is labeled as such — with wording such as “affiliate link,” “sponsored,” or a note that we may earn a commission — placed clearly enough to notice before you click. Our goal is simple: you should never have to guess whether FluTrack stands to earn from a link.

Following the FTC's guidance

In the United States, the Federal Trade Commission asks websites to disclose, clearly and conspicuously, any financial relationship behind a recommendation or a link — so that readers can factor it in. Its Endorsement Guides (16 CFR Part 255) are the plain-language rulebook for this. This page, together with the labels on individual links, is how FluTrack meets that standard: we tell you up front that we may be paid when you buy through certain links, we keep those disclosures near the links themselves, and we do not dress up paid placement as neutral editorial content. When we describe the CDC's data, that description is not sponsored; when a link can earn us a commission, we say so.

Not an endorsement, and not medical advice

An affiliate link is a funding mechanism, not a seal of approval. FluTrack does not test, certify, or vouch for the products and services these links point to, and their inclusion is not an endorsement of any brand, seller, test, device, treatment, or vaccine. Merchants set their own prices, availability, terms, and privacy practices, and we do not control them.

Not medical advice

The information on FluTrack is provided for general informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of a qualified health provider with any questions you may have regarding a medical condition.

Nothing on this page — and no product or service linked from it — should be read as guidance about testing, treatment, prevention, or your personal risk. Decisions about your health belong between you and a qualified health provider, not a link. FluTrack is an independent project and is not affiliated with, endorsed by, or sponsored by the Centers for Disease Control and Prevention (CDC) or any government agency.

Questions

If anything about how FluTrack is funded is unclear, or you spot a link that should be labeled and is not, please tell us and we will fix it. You can also read how affiliate and advertising data is handled in our Privacy Policy, and the governing terms on our Terms of Use page.

The bottom line

FluTrack earns from advertising and from disclosed affiliate links, at no extra cost to you. That revenue keeps the site free — and it never touches the CDC-derived threat level, which is computed the same way for every state and is never for sale. For general information only — not medical advice.
