Uganda

Status: imported poliovirus

Uganda is one of the countries in the “wild poliovirus importation belt” – a band of countries stretching from west Africa to central Africa and the Horn of Africa, which are recurrently re-infected with poliovirus originating from northern Nigeria. The immediate priority is to stop all active outbreaks using mop-up campaigns with monovalent oral polio vaccine in the infected areas, combined with a series of large-scale, synchronized supplementary immunization activities across most of the “importation belt” countries to protect against further importations.

Polio this week in the Horn of Africa

  • Three new cases of wild poliovirus type 1 were reported in the past week. Five cases have been reported in the Horn of Africa to date in 2014 – one WPV1 in Ethiopia and four WPV1 in Somalia. The most recent case had onset of paralysis on 3 June in Mudug, Somalia.
  • The three new cases reported from Mudug in Somalia bring the total no. of cases reported from the Mudug Region (Jariban) this year to four and indicate that the polio outbreak in Somalia continues. The cases are caused by virus closely related to that previously detected in Mogadishu in July 2013. No cases have been detected in the epicentre of the outbreak, in Mogadishu, Banadir region, since 19 July 2013.
  • The most recent immunization activities took place in accessible districts of Somalia on 15-18 June, except for Puntland (which includes Mudug), which followed on 21-24 June. A short-interval additional dose campaign took place on 5-9 July, followed by further campaigns planned for 20-25 July (targeting children under 10) and 5-8 August.
  • Mudug is a remote area with challenging conditions to plan and implement immunization campaigns and with hard-to-reach, under-served nomadic populations. While the proportion of children with three or more doses of oral polio vaccine has risen since 2012, it is still below 80%. None of the children paralyzed in Mudug had ever been vaccinated against polio.
  • Special outreach is currently taking place to reach and vaccinate nomadic communities, as well as to map of these communities to ensure their inclusion in vaccination plans.
  • Djibouti, Ethiopia, Kenya and Somalia all conducted mass vaccination campaigns in June. Ethiopia is also planning to hold a campaign in July and, along with Yemen and Kenya, will conduct a campaign in August.
  • Environmental samples collected in Somali neighbourhoods of Nairobi, Kenya, continue to test negative for WPV since October 2013.
