Worldwide: Poliomyelitis [Update]

The World Health Organization (WHO) has updated the temporary recommendations regarding the international spread of poliovirus. States currently infected with wild poliovirus or circulating vaccine-derived poliovirus (cVDPV) with potential risk of international spread, i.e. Pakistan, Afghanistan and Nigeria, should ensure that all residents and long-term visitors (i.e. > 4 weeks) of all ages receive a dose of polio vaccine between 4 weeks and 12 months prior to international travel. For those undertaking urgent travel (i.e. within 4 weeks) who have not received a dose of polio vaccine in the previous 4 weeks to 12 months, should receive a dose of polio vaccine at least by the time of departure as this will provide benefit, particularly for frequent travellers. Travellers are provided with an International Certificate of Vaccination or Prophylaxis to record their polio vaccination and serve as proof of vaccination.
