COVID-19 self-testing in Nigeria: Stakeholders’ opinions and perspectives on its value for case detection

Abstract

Background COVID-19 testing coverage is limited in Nigeria. Access to rapid SARS-CoV-2 antigen-detection self-testing kits may help improve the detection of asymptomatic and mildly symptomatic cases and increase the country’s low rate of SARS-CoV-2 testing. Before implementing self-testing in Nigeria, assessing the population’s perceptions regarding this approach is imperative. In mid-2021, an exploratory cross-sectional qualitative research was conducted to investigate stakeholders’ values and preferences for SARS-CoV-2 self-testing in Nigeria. Methods In-person and online semi-structured interviews and focus group discussions with healthcare workers, representatives of civil society, and potential implementors of self-testing delivery programs were used to explore values and perceptions around access to conventional provider-initiated COVID-19 testing. Topics included the public’s values in relation to SARS-CoV-2 self-testing, the safe and effective use of SARS-CoV-2 self-testing, and likely actions upon receiving a positive SARS-CoV-2 self-test result. A thematic analysis approach was applied. Results The 58 informants (29 female) reported that Nigeria has limited availability of conventional provider-delivered SARS-CoV-2 testing. While just a few informants were familiar with SARS-CoV-2 self-testing, they generally supported using self-testing as an approach that they felt could assist with early case detection and improve access to testing. Concerns relating to the use of self-testing mainly related to the ability of low-literate individuals to use and interpret the self-tests, the affordability of self-tests, equity of access, and the availability of healthcare system support for those who self-test positive. Conclusion Although the Nigerian public perceive multiple benefits associated with access to SARS-CoV-2 self-testing, the perceived inefficiency of the national health service delivery system may limit the access of users of the kits to psychosocial and clinical support. Nevertheless, in Nigeria, where COVID-19 vaccine coverage is low and the risk of further waves of COVID-19 is high, self-testing may assist in the prompt detection of cases and contribute to halting the spread of the virus.

Self-Diagnosis of SARS-CoV-2 from Saliva Samples at Home: Isothermal Amplification Enabled by Do-It-Yourself Portable Incubators and Laminated Poly-ethyl Sulfonate Membranes

“…To our knowledge, this is the first experimental pilot study that explores this option as a radically different alternative to the typical centralized system of molecular diagnostics prevailing during the COVID-19 pandemic. The use of molecular self-diagnostics [53] was recently suggested (but not experimentally explored) in the context of antigen-based testing in Nigeria. The authors conducted a survey among nearly 60 volunteers to identify the element of perception towards the implementation of self-testing for the detection of SARS-CoV-2 infections among the Nigerian population.…”
