Why This Site Points Elsewhere for Data
Numbers move. Prevalence estimates are revised as screening expands. Treatment guidelines are updated when clinical evidence shifts. A figure written into a webpage — however carefully — can be quietly wrong within a year, and neither you nor the author may know it.
That is not a failure of explanation; it is a feature of how living science works. The job of a plain-language guide is to give you the framework to read current data when you encounter it, not to be a repository of data that may have aged. So when this site says "most people" rather than citing a percentage, or directs you to check current figures, that is deliberate. It is honesty about what a guide can and cannot reliably do.
The Sources That Do It Well
Two organisations publish the figures and clinical guidance that clinicians actually use.
The World Health Organization maintains a dedicated hepatitis C fact sheet, updated on a regular cycle, with global prevalence data, mortality context, and overviews of the policy landscape. It is written for a broad audience and is freely available at who.int. The page you want is filed under Health Topics.
The US Centers for Disease Control and Prevention publishes both surveillance data specific to the United States and a set of clinical guidance documents that are among the most widely cited in the English-speaking world. The relevant section lives at cdc.gov under Viral Hepatitis. The CDC also maintains a plain-language section designed for people who are not clinicians.
For readers outside the United States, national equivalents carry the same weight: NHS England publishes hepatitis C guidance and data through its own channels; the European Centre for Disease Prevention and Control covers the European picture; national health bodies in Canada, Australia and elsewhere maintain comparable resources. Any government health portal searched for "hepatitis C" will surface the current national position.
How to Read What You Find
Official documents can still be dense. A useful orientation: look first for a summary or fact-sheet version, which most bodies publish alongside the technical document. Note the date the document was last reviewed — anything more than two or three years old may predate significant developments in the treatment landscape. If a number or claim matters to your own situation, bring it to your clinician rather than interpreting it alone.
This site's role is to make those conversations easier to enter. The sources above are where they go from there.
