Online health information refers to any medical or paramedical content accessible on the web, produced by institutions, healthcare professionals, media, or individuals. Its reliability directly depends on the source that publishes it, the validation process it has undergone, and its date of update. Staying informed about health through reliable online resources requires knowing how to distinguish these parameters even before reading the content.
Digital Services Act and health content: what the European framework changes
Articles explaining how to spot a reliable medical site often omit a structuring factor: the regulatory framework now weighing on platforms distributing this content. The European regulation Digital Services Act (DSA, EU 2022/2065), fully applicable since February 17, 2024, to all online intermediaries operating within the European Union, changes the game.
Very large platforms (designated VLOP or VLOSE by the European Commission) are legally required to limit the spread of false information, including medical misinformation. Specifically, a social network or search engine classified as VLOP must audit its systemic risks, including health misinformation, and implement documented mitigation measures.
For a reader, this means that the presence of health content on a large platform is no longer a guarantee of neutrality. These platforms apply algorithmic filters whose criteria are not always transparent. Consulting institutional sites or portals validated by professionals remains more reliable than relying on the sorting done by a news feed.
Among the French-speaking portals that aggregate verified content, health information on Virtual Papyrus allows access to resources categorized by theme without going through the filter of a social algorithm.
HDS v2 Reference Framework: data sovereignty as a reliability criterion
The quality of a health site is not limited to the accuracy of its content. How it stores and protects its users’ data also matters. The new HDS v2.0 reference framework, published in the Official Journal on May 16, 2024, requires health data hosts to store them exclusively within the European Economic Area.
This framework adds transparency requirements regarding extraterritorial legislations to which a host may be subject. A health site hosted by a provider subject to foreign surveillance laws (such as FISA in the United States) must now disclose this.
In practice, this criterion helps evaluate the reliability of an online health resource beyond just the displayed content. A site that collects personal data (forms, user accounts, browsing histories) without adhering to the HDS framework exposes its visitors to risks that the editorial content, no matter how rigorous, cannot compensate for.
Check the hosting of a health site
The legal notices and privacy policy of a site must indicate the name of the host and the location of data storage. The absence of these mentions is a warning sign, especially if the site offers to create an account or provide personal medical information.
Reading grid to evaluate an online health resource
Rather than a list of “good” and “bad” sites, a grid of technical criteria allows for judging each encountered content. Five parameters are sufficient to filter out the majority of dubious sources.
- The author is identified and their qualifications are verifiable: a doctor registered with the Order, a researcher affiliated with a recognized laboratory (INSERM, CHU), or a public institution (HAS, Santé publique France). An article without an identifiable author or editorial board loses credibility.
- Primary sources are cited: reliable content refers to studies published in peer-reviewed journals, official recommendations, or sourced epidemiological data. The absence of bibliographic references in an article that presents figures or therapeutic recommendations is a marker of unverified content.
- The publication or update date is visible: medical research evolves, and an article on a treatment that is several years old may be outdated. Institutional sites like those of INSERM or HAS systematically display the date of the last revision.
- The tone remains factual and does not use emotional triggers: content that plays on fear, urgency, or the promise of miraculous healing strays from medical consensus. Health fake news exploits these levers to capture attention.
- The site does not condition access to information on a purchase: reliable medical content is not a sales funnel. If reading an article consistently leads to the promotion of a dietary supplement or medical device, editorial neutrality is compromised.
Health news and risks of misinformation on social networks
Social networks remain the primary channel through which health fake news circulates. The Covid crisis highlighted the phenomenon of infodemic, but the problem persists well beyond the pandemic context, on topics such as vaccination, nutrition, or alternative medicine.
The short format of social posts (posts, stories, videos of a few seconds) does not allow for conveying the complexity of a medical subject. Relevant health content requires context, nuances, and sources, three elements that the social format systematically compresses.
Cross-check sources rather than share
Before considering health information seen on a social network as reliable, verifying it on at least two institutional sites (Ameli.fr, HAS, INSERM, Santé publique France) significantly reduces the risk of relaying false information. This reflex of cross-checking sources is more effective than any label or certification displayed on a site.
The reliability of online medical information does not depend on a single criterion but on a combination: the author’s identity, cited sources, date of update, regulatory framework of the platform, data protection. No shortcut replaces this verification, and the healthcare professional remains the final filter before any medical decision.
