Two separate circulating vaccine-derived poliovirus type 2s (cVDVP2s) have been confirmed.  The first cVDPV2 strain has been isolated from two acute flaccid paralysis (AFP) cases from two districts in Haut-Lomami province, with onset of paralysis on 20 February and 8 March 2017.  The second cVDPV2 strain has been isolated from Maniema province, from two AFP cases (with onset of paralysis on 18 April and 8 May) and a healthy contact in the community.

Outbreak response plans are currently being finalized, consisting of supplementary immunization activities (SIAs) with monovalent oral polio vaccine type 2 (mOPV2), in line with internationally-agreed outbreak response protocols.  Surveillance and immunization activities are being strengthened in neighbouring countries. 

 

WHO advice

WHO’s International Travel and Health recommends that all travellers to polio-affected areas be fully vaccinated against polio. Residents (and visitors for more than 4 weeks) from infected areas should receive an additional dose of OPV or inactivated polio vaccine (IPV) within 4 weeks to 12 months of travel. 

As per the advice of an Emergency Committee convened under the International Health Regulations (2005), efforts to limit the international spread of poliovirus remains a Public Health Emergency of International Concern (PHEIC).  Countries affected by poliovirus transmission are subject to Temporary Recommendations. 

To comply with the Temporary Recommendations issued under the PHEIC, any country infected by poliovirus should declare the outbreak as a national public health emergency and consider vaccination of all international travellers.
