Emergency? Don’t use a website. Call the local emergency number: 112 works across Europe and in many other countries, 911 in the U.S. and Canada, 999 in the UK. Get help right away for chest pain, trouble breathing, signs of a stroke (face drooping, arm weakness, slurred speech), heavy bleeding, a severe allergic reaction, confusion or fainting, a high fever with a stiff neck, or signs of serious dehydration.
For the minor stuff on the road (an upset stomach, a rash, a cough that won’t quit), a good symptom checker helps you decide whether it can wait, needs a pharmacist, or needs a doctor today.
Symptom checkers I trust
- Mayo Clinic Symptom Checker: pick a symptom and answer a few questions to see possible causes. Free, no account.
- WebMD Symptom Checker: a guided checker with links to plain-English articles on each condition.
- Ada: a phone app that asks you questions like a clinician would, then suggests next steps.
- NHS inform self-help guides: clear guides from Scotland’s health service on common problems and when to seek care.
- CDC Travelers’ Health: check what’s going around at your destination (malaria, dengue and other travel illnesses).
Talk to a real person
- Your travel insurance assistance line. Most policies have a 24/7 number with nurses or doctors, and they can point you to a vetted local clinic.
- Telehealth from your health plan. Check before you leave whether it works while you’re abroad.
- Your embassy. U.S. embassies keep lists of local doctors and hospitals. Find yours at usembassy.gov.
- Pharmacists. In much of the world they can advise on minor problems without an appointment.
