Background: Between 2013 and 2014, the Horn of Africa countries experienced a severe and prolonged outbreak of polio viruses. It started in one district in Somalia but quickly became a national and even international disaster, crossing international boundaries into Kenya and Ethiopia. This paper documents experiences in the establishment and contributions of the Polio Communication Network (PCN) to the polio outbreak response in the outbreak countries of Somalia, Kenya and Ethiopia from 2013 to 2015. Process: The establishment of the PCN network of partnerships and technical assistance was designed to implement a strategic communication response. Various strategies were used to establish the PCN. Some of these strategies included partnerships with faith-based organizations; involvement of local leaders in microplanning; social mobilization committees and research, monitoring, evaluation and documentation structures. Major Outcomes: PCN contributions through sustained high levels of community awareness of polio rounds were demonstrated. The contributions of the context-sensitive approaches included significant gains in reaching traditionally missed, hard-to-reach, pastoral communities with polio information, improved communication capacity, and successful closure of the outbreak within the expected timeline. This PCN experience provides important communication lessons relevant to polio eradication and other public health programmes. The focus on building capacity in areas such as monitoring, and data collection generated social data that led to the communication approaches making a significant impact. PCN contributed to a better understanding of the behavioral and environmental factors affecting the demand for, and uptake of, health services in the HoA which can be extended to most of the countries in the HoA with the same demographic and epidemiological realities. Conclusion: The use of the PCN helped bring the 2013-2014 polio outbreak under control and illustrates how the PCN can help drive progress towards the realization of the agenda of the universal health coverage and vision 2030 agenda in the African Region and elsewhere.
Background: There has been civil strife, spanning more than two decades in some countries and recurrent natural disasters in the Horn of Africa (HoA). This has consistently maintained these countries in chronic humanitarian conditions. More important however is the fact that these crises have also denied populations of these countries access to access to lifesaving health services. Children in the difficult terrains and security compromised areas are not given the required immunization services to build their immunity against infectious diseases like the poliovirus. This was the situation in 2013 when the large outbreaks of poliovirus occurred in the HoA. This article reviews the epidemiology, risk, and programme response to what is now famed as the 2013-204 poliovirus outbreaks in the HoA and highlights the challenges that the programme faced in interrupting poliovirus transmission here. Methods: A case of acute flaccid paralysis (AFP) was defined as a child <15 years of age with sudden onset of fever and paralysis. Polio cases were defined as AFP cases with stool specimens positive for WPV. Results: Between 2013 and 2016, when transmission was interrupted 20,266 polio viruses were in the Horn of Africa region. In response to the outbreak, several supplementary immunization activities were conducted with oral polio vaccine (OPV) The trivalent OPV was used initially, followed subsequently by bivalent OPV, and targeting various age groups, including children aged <5 years, children aged <10 years, and individuals of any age. Other response activities were undertaken to supplement the immunization in controlling the outbreak. Some of these activities included the use of various communication strategies to create awareness, sensitize and mobilize the populations against poliovirus transmission. Conclusions: The outbreaks were attributed to the existence of clusters of unvaccinated children due to inaccessibility to them by the health system, caused by poor geographical terrain and conflicts. The key lesson therefore is that the existence of populations with low immunity to infections will necessary constitutes breeding grounds for disease outbreak and of course reservoirs to the vectors. Though brought under reasonable control, the outbreaks indicate that the threat of large polio outbreaks resulting from poliovirus importation will remain constant unless polio transmission is interrupted in the remaining polio-endemic countries of the world.
