WHO Fact Sheets: The Quickest Way to Check Trusted Health Facts
Every day, health claims fly around WhatsApp, TikTok and Facebook: a miracle food that “cures” diabetes, a scary warning about a common medicine, a secret remedy “doctors don’t want you to know.” Some claims are true, many are half-true, and some are dangerous nonsense. Before you believe or forward any of them, there is a free two-minute check you can run: the World Health Organization’s fact sheets. They are one of the most reliable health resources on the internet, and almost nobody outside the medical world knows they exist.
What is a WHO fact sheet?
A fact sheet is a short, plain-language summary of a health topic, published by the World Health Organization (WHO) — the United Nations agency responsible for global health. The WHO maintains an A-to-Z library of them, covering well over 200 topics, and each one is prepared and reviewed by health experts and updated as the evidence changes.
Every fact sheet follows a reader-friendly pattern. It opens with a box of key facts — the handful of things you most need to know. Then it explains the topic in more depth: what the condition or issue is, who it affects, the main symptoms or causes, how it is treated or prevented, and what WHO itself is doing about it. Most people only need the key facts box, which takes about two minutes to read.
The topics they cover
The range is much wider than most readers expect.
Diseases and conditions make up the biggest group: diabetes, cancer, heart disease, stroke, asthma, malaria, tuberculosis, HIV, dengue, depression, dementia, epilepsy and hundreds more, from the very common to the very rare.
Everyday habits and prevention are covered too, in sheets on healthy diet, physical activity, tobacco and nicotine, alcohol, reducing salt (sodium), sugars, and obesity. If a viral post claims a certain food or habit is deadly — or magically protective — there is probably a fact sheet that gives the measured, evidence-based position.
Medicines, vaccines and safety get their own set: essential medicines, immunization coverage, antimicrobial resistance (the growing problem of infections that no longer respond to antibiotics), substandard and falsified medical products, and patient safety.
Emergencies and environment round out the library: Ebola, cholera and COVID-19, mental health in emergencies, air pollution, climate change and health, heat, drinking-water, sanitation and road traffic injuries.
How to use a fact sheet to check a claim
First, pin down the exact claim. “Turmeric cures diabetes” is checkable; “natural stuff is better” is not. Second, search the WHO fact sheet list for the topic — in this case, the diabetes sheet. Third, read the key facts and the treatment section. You will quickly learn what actually manages the condition (healthy diet, activity, medication when prescribed) and notice that the miracle cure is simply not there.
Fourth, compare the numbers. Viral posts love dramatic statistics with no source. Fact sheets give real figures — how many people are affected, what share of deaths a condition causes — that you can hold up against the claim. Fifth, check the date. Fact sheets are revised, so you are reading current guidance, not a screenshot from a decade ago.
Along the way, fact sheets teach you the red flags of health misinformation: promises of a fast cure, claims that one product treats everything, fear-based language, personal stories instead of data, and of course, a link asking you to buy something or forward the message quickly.
A two-minute check, in real life
A quick example shows the habit in action. Suppose a forwarded message warns that a common painkiller is “banned worldwide” and urges you to stock up on an herbal alternative instead. Open the WHO library, search for the medicine and for the sheet on substandard and falsified medical products, and you will find what regulators actually say: which products are approved, what the genuine risks are, and how to spot fake medicines. Nine times out of ten, the dramatic claim collapses within minutes — and you have stopped your family group chat from passing it on. The same quick check works for vaccine rumours, diet fads and outbreak scares. It costs nothing, needs no sign-up, and the sheets are published in several languages, which makes them just as useful for checking claims shared by relatives abroad.
One honest limitation
Fact sheets give general information for the public; they are not personal medical advice, and they cannot diagnose your situation. For your own health decisions, a doctor who knows your history is irreplaceable. Think of the fact sheets as a lie detector for claims, not a replacement for a clinic visit.
The bottom line
You do not need a medical degree to protect yourself from health misinformation. You need one trustworthy bookmark. The WHO fact sheet library is free, fast, written for ordinary readers and maintained by the world’s leading public health authority. Next time a dramatic health claim lands in your feed, spend two minutes with the matching fact sheet before you believe it — and especially before you share it.
