UMEM Educational Pearls

General Information:

  • Previously, polio had been decreasing in incidence and nearing worldwide eradication.
  • From 2012 to 2013, the incidence doubled from 223 to 403 cases, and is anticipated to be higher in 2014 (May and June are the highest transmission months).
  • The WHO declared a Public Health Emergency of International Concern on Monday (5/5/14).  
  • Polio has been transmitted across international borders by travelers and is still circulating within endemic areas. 
  • In addition to improving vaccination within these countries, the public health emergency calls for all travelers from these countries to complete a polio vaccine series and travel with vaccination records.

Relevance to the EM Physician:

  • Previously unvaccinated travelers should be given a 3-dose polio vaccine series.
  • If a traveler has completed the 3-dose series in the past, the CDC recommends one single lifetime booster dose of inactivated polio virus (IPV).

Bottom Line:

  • Polio is increasing in incidence in 10 countries: Syria, Pakistan, Cameroon, Afghanistan, Equatorial Guinea, Ethiopia, Iraq, Israel, Somalia and Nigeria.  
  • For those who received an IPV series as a child, a single IPV booster is recommended for travelers to those countries to assure lifelong immunity.
