† Wild poliovirus serotype genetic cluster.
‡ High risk: Susceptible counties to polio outbreaks that were determined through risk assessment. The risk assessment examined the counties’ routine immunization coverage, AFP surveillance performance, and coverage of the most recent SIA round.

We thank the U.S. Agency for International Development for funding the CORE Group Polio Project. We also thank the Department of Disease Surveillance and Response Unit (DRSU) of the Ministry of Health, Kenya; the WHO-Horn of Africa Coordination Office; and UNICEF Polio Team for their technical support and cooperation. We commend the work of CORE Group Polio Project partners (World Vision-Kenya, Catholic Relief Service-Kenya, International Rescue Committee (IRC), American Refugee Committee (ARC), Adventist Development and Relief Agency (ADRA) Kenya, and Somali-AID) for the important contributions to the success of the Cross-Border Health Initiative. We wish to recognize the border frontline health workers, community mobilizers, and polio community influencers who are working selflessly every day in the most challenging context of the Horn of Africa to protect children from polio.
