Mediscanner Symptom Checker

The free Mediscanner symptom checker runs entirely in your browser. Select what you're feeling from the common symptoms below, or type your own — the Mediscanner symptom checker ranks 268 viruses by how closely they match your symptoms, for information only.

This is not a diagnosis. Symptom overlap does not confirm any condition. If you feel seriously unwell, contact a doctor or your local emergency number straight away.

Frequently asked questions

What is Mediscanner?

Mediscanner is an educational health-information website linked to the Viruskenner programme. It explains viruses, symptoms, and prevention in plain language. It is not a medical device and does not provide medical advice or diagnosis.

Is Mediscanner a substitute for a doctor?

No. It is for general information and awareness only. For diagnosis or treatment, always consult a qualified healthcare professional.

How does the symptom checker work?

It runs entirely in your browser and ranks 268 viruses by how closely they match the symptoms you select. It gives possible matches for awareness, not a diagnosis.

Is my data private?

Yes. Core tools such as the symptom checker run on your own device, and the symptoms you select are not sent to a server. Mediscanner is built to align with the GDPR.

What does the disease map show?

It shows reference locations and risk levels for the viruses Mediscanner tracks. It is an awareness tool, not a real-time outbreak feed.

Where does the news come from?

The news section gathers public-health headlines from sources such as WHO, ECDC, and CDC.

Which languages are supported?

English and Dutch. The site can follow your browser language automatically.

Do I need an account?

No. The main tools are free to use without signing in.

What should I do in an emergency?

Call your local emergency number (112 in the EU) or go to the nearest emergency department. Do not rely on an online tool in an emergency.
