What to know about polio when you are traveling
Global health authorities are urging travellers to stay alert as poliovirus continues to circulate in multiple regions worldwide, prompting updated travel advisories in 2026.
Recent guidance from the U.S. Centers for Disease Control and Prevention (CDC) highlights that more than 30 countries have reported poliovirus detections in the past year, including parts of Asia, Africa, Europe and the Middle East. While the overall risk for most travellers remains low, experts stress that precautions are essential, especially when visiting high-risk areas.
Polio is a highly contagious viral disease that spreads through contaminated food, water, or contact with infected bodily fluids. In most cases, symptoms are mild or absent, but severe infections can lead to paralysis or even death.
Health agencies agree that vaccination is the most effective protection. Travellers should ensure they are fully immunised before departure. Adults who have already completed their routine vaccination may also require a one-time booster dose if traveling to affected regions. Unvaccinated or partially vaccinated individuals are strongly advised to complete their doses prior to travel.
In some countries, proof of recent polio vaccination may be required for entry or exit, particularly in areas with active transmission. The World Health Organization also recommends an additional dose within four weeks to 12 months before international travel for those at risk.

Experts also recommend basic hygiene practices such as frequent handwashing and consuming safe food and water. As global vaccination rates decline in some regions, maintaining immunisation and awareness remains key to preventing the re-emergence of this once nearly eradicated disease.
