Polio is still a global health emergency. Here is what that means for your trip

What happened

On 15 September 2026, the National Travel Health Network and Centre, the UK's official travel health service for health professionals, published an update on polio. Polio remains a Public Health Emergency of International Concern. That designation, often shortened to PHEIC, is the highest formal alert the World Health Organization can issue. Polio has held it since 2014, and it has been reviewed roughly every three months ever since. The 45th meeting of the relevant emergency committee was convened on 14 May 2026, and its statement was published on 25 August 2026. The committee reviewed progress on both wild poliovirus and vaccine-derived poliovirus, and decided the emergency should continue. Seventeen countries had their status changed since the previous review: Algeria, Burkina Faso, Congo, Equatorial Guinea, Gambia, Guinea, Israel, Malawi, Mali, Mauritania, Nigeria, Palestine, Poland, Senegal, South Sudan, Togo and Zambia. For UK travellers, the advice is straightforward. Complete the routine UK polio vaccination schedule, carry documentary evidence of your vaccination, and follow strict food, water and hand hygiene precautions. The inactivated polio vaccine used in the UK protects against all three types of poliovirus. Some countries require an International Certificate of Vaccination or Prophylaxis before you can leave. That requirement catches people out.

Why this matters

Polio is a virus that mostly causes mild illness or no symptoms at all. In a small proportion of cases it attacks the nervous system and causes paralysis, which can be permanent. There is no cure. Vaccination is the only protection. Britain has been free of naturally occurring polio for decades, and most people under sixty have never knowingly met anyone affected by it. That is the vaccine working, not the disease disappearing. Two details in this update deserve attention. The first is that the list of countries includes several that many people would not associate with polio at all. Poland and Israel are on it. This usually reflects poliovirus being detected in sewage sampling rather than cases of paralysis, and it shows how far the virus can travel when vaccination rates dip anywhere. The second is the certificate requirement. In some affected countries, the rule is not about protecting you. It is about stopping the virus leaving with you. Travellers can be asked for proof of a polio dose given between four weeks and twelve months before departure. Arriving at an airport without it can mean being vaccinated on the spot or, occasionally, not travelling. Britain's own experience is a reminder that this is not only about faraway places. Poliovirus was detected in London sewage in 2022, prompting a catch-up vaccination campaign for children in the capital.

What the evidence actually says

It is worth being precise about what this update is and is not, because the framing matters. This is not news of an outbreak. No new emergency has been declared. The emergency committee reviewed the situation and decided the existing PHEIC should stay in place, which is what it has decided at every review since 2014. NaTHNaC has published a traveller-facing update reflecting that. So the honest reading is: the situation has not worsened dramatically, and it has not been resolved either. Polio eradication has been close for years without being finished. The seventeen countries with changed status include both additions and reclassifications. A change of status does not automatically mean a country has got worse - it can reflect improved surveillance, or a period elapsing since the last detection. On risk to the individual traveller: it is low. Polio is a serious disease, but the chance of a fully vaccinated British traveller catching it is very small. The practical issue for most people is administrative - the certificate requirement - rather than medical. The UK schedule gives polio vaccine at 8, 12 and 16 weeks, again at around three years four months, and again at around fourteen years. Most adults who grew up in Britain have had it. Boosters for travel are recommended if it has been ten years or more since your last dose, and are required for some destinations.

Qurexa perspective

Travel vaccinations are one of the few areas where planning ahead genuinely changes what is possible, and where leaving it late closes doors. Many travel vaccines need to be given several weeks before departure to work properly, and the polio certificate requirement specifically asks for a dose given at least four weeks before you leave. A week before your flight is often too late. The other thing worth saying, since we deliver prescriptions, is about repeat medication and travel. People concentrate on vaccines and forget that they will be away when their next prescription is due. Ask your GP practice early if you need a longer supply before a trip - practices are usually willing, but they need notice, and requests made the week before departure are the ones that go wrong. If you are travelling for longer than your usual supply covers, raise it at least a month ahead.

Practical advice

Start with your own record. If you were born in the UK and had your childhood vaccinations, you have almost certainly had polio vaccine. Your GP practice holds the record, and many people can now see it in the NHS App. Check the specific country you are going to, not the region. Requirements differ sharply between neighbouring countries. The FCDO travel advice pages and TravelHealthPro both list entry requirements by destination. Allow six to eight weeks. That is the standard advice for any travel vaccination, and it is not padding. Some vaccines need more than one dose spaced apart. If a certificate is required, get it properly documented. An International Certificate of Vaccination or Prophylaxis is a specific yellow document, not a printout of your GP record. Travel clinics can issue them. Remember the everyday precautions. Polio spreads mainly through contaminated food and water. Bottled or properly treated water, well-cooked food, careful hand washing, and caution with ice and salad are the same precautions that protect you from far more common travel illnesses. And keep your travel insurance in order. Insurance can be invalidated if you travel against official advice or without required vaccinations.

What to know

UK travel health advisers updated their polio guidance on 15 September 2026. Polio remains a Public Health Emergency of International Concern, as it has since 2014, and seventeen countries had their status changed at the latest review. For most British travellers the medical risk is low, because the UK childhood schedule protects well. The practical risk is administrative: some countries require documented proof of a recent polio dose before you can leave, and that dose usually has to be at least four weeks old. Check your destination's specific requirements, allow six to eight weeks before you fly, and be strict about food, water and hand hygiene. And while you are planning, sort out your repeat prescriptions too. That is the thing people most often leave too late.
