Advice for Travellers

Polio is a serious infection caused by the poliovirus. The virus lives in an infected person’s throat and intestines. It enters the body through the mouth and spreads through:

  • contact with the poo from an infected person
  • droplets from a cough or sneeze from an infected person, this is less common

You can become infected if you:

  • have an infected person's poo on your hands and you touch your mouth
  • put objects in your mouth that are contaminated with the infected poo
  • consume food and/or water that has been contaminated with the poo from an infected person

You should consider having a booster dose of polio vaccine if it has been more than 10 years since your last booster and you are travelling to a country where polio remains a problem.
