The Committee concluded that:

  • the international spread of poliovirus remains a Public Health Emergency of International Concern (PHEIC)
  • Afghanistan is no longer exporting wild poliovirus, but is still considered to be an infected country with WPV1
  • Madagascar and Myanmar are no longer considered infected but remain vulnerable to infection.
  • Somalia has been removed from the list of countries that remain vulnerable to infection.

As of 11 November 2016, the polio status of countries is outlined below [1].

States currently exporting wild poliovirus or cVDPV:

  • Pakistan

States infected with wild poliovirus or cVDPVs but not currently exporting:

  • Afghanistan (WPV1)
  • Guinea (cVDPV)
  • Lao People’s Democratic Republic (cVDPV)
  • Nigeria (WPV1 and cVDPV)

  • Cameroon (cVDPV)
  • Central African Republic* (cVDPV)
  • Chad (cVDPV)
  • Equatorial Guinea (cVDPV)
  • Niger (cVDPV)
  • Madagascar (cVDPV)

Advice for travellers

Polio is transmitted via the faecal-oral route, either by exposure to water contaminated by infected human faeces, or by person to person contact. You should practise strict food, water and personal hygiene.

Independent of your destination, you should complete a primary vaccination course for polio according to the UK schedule. Travellers are encouraged to carry documentary evidence of their polio vaccination status.

An International Certificate of Vaccination or Prophylaxis is required by some countries see the Country Information pages for country specific information.

Advice for health professionals

All travellers regardless of destination should be up to date with routine vaccination courses and boosters as recommended in the UK. All country specific polio vaccine recommendations and certificate requirements remain unchanged until further notice. See the Country information pages for country specific recommendations.
