Polio update: outbreak in the Horn of Africa

Horn of Africa

    Five new WPV cases were reported in the past week (two WPV1s from Somalia and three WPV1s from Kenya), bringing the total number of WPV1 cases in the region to 14 (nine WPV1s from Somalia and five WPV1s from Kenya).  Two of these new cases are the most recent and had onset of paralysis on 18 May (both from Kenya).

      Outbreak response activities are continuing across the Horn of Africa:

      • In Somalia, two large-scale immunization campaigns have already been implemented, including in Banadir (which includes Mogadishu), including targeting children aged less than ten years.   Lessons from these campaigns are now being addressed in preparation of the next rounds starting on 12 June.  In Banadir, all age groups are being targeted.  Focus is on fine-tuning microplans to include schools, more clearly define vaccinator team daily workloads, improving supervision and expanding the scope and content of monitoring activities.
      • In Kenya, immunization activities began on 26 May to reach nearly 440,000 children aged less than 15 years across the Dadaab area.  Preparations are ongoing for the next SNIDs, on 15 June, covering broader areas including all age groups in the Dadaab area.  Further campaigns planned for late June and mid-August.
      • Immunization campaigns are also planned and being conducted in other areas of the Horn of Africa, notably Ethiopia and Yemen, to urgently boost population immunity levels and minimize the risk of spread of the outbreak.
      • In Ethiopia, in border areas with Kenya and Somalia, an immunization activity was held on 31 May (targeting children aged less than 15 years).  Focus was particularly on reaching children in refugee camps.  Broader activities are planned to start 16 June and in early July.
      • In Yemen, activities were held last week (2-5 June) to reach 2.1 million children, with a second round planned for late June to reach 3.5 million children and National Immunization Days in August.

      This week we are celebrating Vaccination Week in the Americas

      This April, the countries and territories of the Americas and the Pan American Health Organization will celebrate Vaccination Week in the Americas. This initiative is now in its 11th year and has been a key driver of progress in immunization.

      Over the last decade, more than 411 million people have been vaccinated under the umbrella of Vaccination Week in the Americas. 44 countries and territories in the Region have committed to celebrating this milestone initiative in 2013.

      The success of Vaccination Week in the Americas (VWA) has served as a model for other Regions of the WHO in the implementation of successful sister initiatives. 2012 marked a milestone as the globe celebrated the first World Immunization Week (WIW), later endorsed with a resolution at the World Health Assembly.
