Follow the source
Factual explanations link to primary public health sources where relevant. We separate established information from original exercises, fictional examples and questions that require local verification. Sources were checked when each article was prepared; linked guidance may change.
About the byline
Articles are published under the site’s editorial byline. This is not a claim of clinical authorship or medical peer review. We do not present the material as personalised medical advice. For individual health concerns, consult a qualified healthcare professional.
Illustrations and corrections
Our conceptual illustrations are created with AI and labelled as illustrations. They do not document real people, facilities or outcomes. Dates appear on articles. When revising factual content, we retain a clear updated date and review the linked evidence.
