WHO updates polio immunization recommendations for travellers

To minimise the risks of acquiring polio (for travellers to infected areas) and of reinfection of polio-free areas (by travellers from infected areas), the World Health Organization (WHO) has updated its polio immunization recommendations for travellers in its publication, International travel and health 2011.

All travellers to and from countries or areas reporting wild poliovirus should be adequately vaccinated. Travellers to countries or areas reporting indigenous wild poliovirus who have previously received three or more doses of oral polio vaccine (OPV) or inactivated polio vaccine (IPV) should be offered another dose of polio vaccine as a once-only dose before departure. Non-immunized individuals intending to travel to these countries or areas should complete a primary schedule of polio vaccination, using either IPV or OPV.

Individuals living in countries or areas reporting indigenous wild poliovirus should have completed a full course of vaccination against polio, preferably with OPV, before travelling abroad. Such travellers should receive an additional dose of OPV 1-12 months before each international journey.

In case of urgent travel, a minimum of one dose of OPV should be given, ideally four weeks before departure.
