Longer and healthier lives for all Africans by 2030: perspectives and action of WHO AFRO

Polio Outbreak Investigation and Response in The Horn of Africa: 2013-2016

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.

Establishment and Use of Polio Communication Network in Response to Polio in Outbreak Countries of the Horn of Africa: 2013-2014

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.

Strengthening national health research systems in the WHO African Region - progress towards universal health coverage

BACKGROUND

Health challenges and health systems set-ups differ, warranting contextualised healthcare interventions to move towards universal health coverage. As such, there is emphasis on generation of contextualized evidence to solve local challenges. However, weak research capacity and inadequate resources remain an impendiment to quality research in the African region. WHO African Region (WHO AFR) facilitated the adoption of a regional strategy for strengthening national health research systems (NHRS) in 2015. We assessed the progress in strengthening NHRS among the 47 member states of the WHO AFR.

METHODS

We employed a cross sectional survey design using a semi structured questionnaire. All the 47member states of WHO AFR were surveyed. We assessed performance against indicators of the regional research strategy, explored facilitating factors and barriers to strengthening NHRS. Using the research barometer, which is a metric developed for the WHO AFR we assessed the strength of NHRS of member states. Data were analysed in Excel Software to calculate barometer scores for NHRS function and sub-function. Thematic content was employed in analysing the qualitative data. Data for 2014 were compared to 2018 to assess progress.

RESULTS

WHO AFR member states have made significant progress in strengthening their NHRS. Some of the indicators have either attained or exceeded the 2025 targets. The average regional barometer score improved from 43% in 2014 to 61% in 2018. Significant improvements were registered in the governance of research for health (R4H); developing and sustaining research resources and producing and using research. Financing R4H improved only modestly. Among the constraints are the lengthy ethical clearance processes, weak research coordination mechanisms, weak enforcement of research laws and regulation, inadequate research infrastructure, limited resource mobilisation skills and donor dependence.

CONCLUSION

There has been significant improvement in the NHRS of member states of the WHO AFRO since the last assessment in 2014. Improvement across the different objectives of the regional research strategy is however varied which compromises overall performance. The survey highlighted the areas with slow improvement that require a concerted effort. Furthermore, the study provides an opportunity for countries to share best practice in areas of excellence.

Inequities in Access to Maternal Health Care in Enugu State: Implications for Universal Health Coverage to Meet Vision 2030 in Nigeria

We explored the equity issues in access to maternal health services in Enugu State, Nigeria. We conducted a cross-sectional survey of 1,600 women who had babies within 6 months prior to the survey, drawn from four urban and rural local government areas in Enugu State of Nigeria, using structured questionnaire. Focus group discussions were held with grandmothers and fathers of the new babies. In-depth interviews were held with health workers. Results showed that inequities exist in access to quality health service when the mothers needed health care. The inequities in access to quality antenatal care (ANC) services were driven mainly by the type of localities of the mothers. Mothers who lived in the urban areas had better access ( p = .013). Other factors that facilitated access to better ANC services included being educated ( p = .049), being older ( p = .009), and belonging to the richer wealth quintile ( p < .001). With respect to access to health service when in need of health, differentials were seen with respect to living in urban residence ( p < .001), distance to the health facilities ( p < .001), and being rich ( p < .001). Access to health services was associated with odds ratio of 3.6 (95% CI [2.9, 4.4]) and 1.54 (95% CI [1.3, 2.0]) for living in urban residence and existence of good ANC service points, respectively. Similarly, living in urban areas was associated with an odds ratio of 1.3 (95% CI [1.1, 1.6]) of having access to good ANC services. These inequities in access to health service were also captured in the qualitative data. Suboptimal access to quality health care by segments of the populations poses challenge to universal health coverage in Enugu State. Action is needed to promote coordinated delivery of health services to ensure no one is left behind, irrespective of where they live or the socioeconomic strata they are born into.
