Objectives: Home diagnostics are essential to assist members of the general population become active agents of case detection. In Indonesia, a country with an over‐burdened healthcare system, individuals could use rapid SARS‐CoV‐2 antigen tests to self‐detect COVID‐19. To assess the general population's values and attitudes towards SARS‐CoV‐2 self‐testing, a survey was conducted in mid‐2021 in Jakarta and the provinces of Banten and North Sulawesi.Methods: This was a quantitative survey that approached respondents in >600 randomly selected street‐points in the three study geographies in July–August 2021. A 35‐item questionnaire was used to collect data on key variables, such as likelihood to use a SARS‐CoV‐2 self‐test, willingness to pay for a self‐test device, and likely actions following a positive self‐test result. Bivariate and multivariate regression analyses were performed.Results: Of 630 respondents (318 were female), 15.53% knew about COVID‐19 self‐testing, while 62.70% agreed with the idea of people being able to self‐test at home, unassisted, for COVID‐19. If self‐tests were available in Indonesia, >60% of respondents would use them if they felt it necessary and would undertake regular self‐testing for example weekly if recommended. Upon receiving a positive self‐test result, most respondents would communicate it (86.03%), request post‐test counselling (80.79%), self‐isolate (97.46%), and/or warn their close contacts (90.48%).Conclusions: The use of rapid SARS‐CoV‐2 antigen detection tests for self‐testing appears acceptable to a majority of the Indonesian public, to learn whether they have COVID‐19. Self‐testing should be prioritised to complement to an over‐burdened healthcare system by helping the public, asymptomatic individuals included, become agents of change in epidemiological surveillance of SARS‐CoV‐2 in their communities.

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.

Background: The prevalence of hepatitis C virus (HCV) among people who inject drugs (PWID) continues to be a major public-health burden in this highly stigmatised population. To halt transmission of HCV, rapid HCV self-testing kits represent an innovative approach that could enable PWID to know their HCV status and seek treatment. As no HCV test has yet been licenced for self-administration, it is crucial to obtain knowledge around the factors that may deter or foster delivery of HCV self-testing among PWID in resource-constrained countries. Methods: A qualitative study to assess values and preferences relating to HCV self-testing was conducted in mid-2020 among PWID in the Bishkek and Chui regions of Kyrgyzstan. Forty-seven PWID participated in 15 individual interviews, two group interviews (n = 12) and one participatory action-research session (n = 20). Responses were analysed using a thematic analysis approach with 4 predefined themes: awareness of HCV and current HCV testing experiences, and acceptability and service delivery preferences for HCV self-testing. Informants’ insights were analysed using a thematic analysis approach. This research received local ethics approval. Results: Awareness of HCV is low and currently PWID prefer community-based HCV testing due to stigma encountered in other healthcare settings. HCV self-testing would be accepted and appreciated by PWID. Acceptability may increase if HCV self-testing: was delivered in pharmacies or by harm reduction associations; was free of charge; was oral rather than blood-based; included instructions with images and clear information on the test’s accuracy; and was distributed alongside pre- and post-testing counselling with linkage to confirmatory testing support. Conclusions: HCV self-testing could increase awareness of and more frequent testing for HCV infection among PWID in Kyrgyzstan. It is recommended that peer-driven associations are involved in the delivery of any HCV self-testing. Furthermore, efforts should be maximised to end discrimination against PWID at the healthcare institutions responsible for confirmatory HCV testing and treatment provision.

Background: Accessible, safe, and client-centered SARS-CoV-2 testing services are an effective way to halt its transmission. Testing enables infected individuals to isolate or quarantine to prevent further transmission. In countries with limited health systems and laboratory capacity, it can be challenging to provide accessible and safe screening for COVID-19. Self-testing provides a convenient, private, and safe testing option; however, it also raises important concerns about lack of counseling and ensuring timely reporting of self-test results to national surveillance systems. Investigating community members’ views and perceptions regarding SARS-CoV-2 self-testing is crucial to inform the most effective and safe strategies for implementing said testing. Objective: We aimed to determine whether SARS-CoV-2 self-testing was useful to diagnose and prevent the spread of SARS-CoV-2 for populations in low-resource settings and under which circumstances it would be acceptable. Methods: This multisite, mixed methods, observational study will be conducted in 9 countries—Brazil, India, Indonesia, Kenya, Malawi, Nigeria, Peru, the Philippines, and South Africa—and will consists of 2 components: cross-sectional surveys and interviews (semistructured and group) among 4 respondent groupings: the general population, general population representatives, health care workers, and decision-makers. General population and health care worker survey responses will be analyzed separately from each other, using bivariate and multivariate inferential analysis and descriptive statistics. Semistructured interviews and group interviews will be audiorecorded, transcribed, and coded for thematic comparative analysis. Results: As of November 19, 2021, participant enrollment is ongoing; 4364 participants have been enrolled in the general population survey, and 2233 participants have been enrolled in the health care workers survey. In the qualitative inquiry, 298 participants have been enrolled. We plan to complete data collection by December 31, 2021 and publish results in 2022 via publications, presentations at conferences, and dissemination events specifically targeted at local decision-makers, civil society, and patient groups. Conclusions: The views and perceptions of local populations are crucial in the discussion of the safest strategies for implementing SARS-CoV-2 self-testing. We intend to identify sociocultural specificities that may hinder or accelerate the widespread utilization of SARS-CoV-2 self-testing.

Background: The advent of direct-acting antivirals (DAAs) and point-of-care (POC) testing platforms for hepatitis C allow for the decentralization of care to primary care settings. In many countries, access to DAAs is generally limited to tertiary hospitals, with limited published research documenting decentralized models of care in low-and middle-income settings. Objective: This study aims to assess the feasibility, acceptability, effectiveness, and cost-effectiveness of decentralized community-based POC testing and DAA therapy for hepatitis C among people who inject drugs and the general population in Yangon, Myanmar. Methods: Rapid diagnostic tests for anti-hepatitis C antibodies were carried out on-site and, if reactive, were followed by POC GeneXpert hepatitis C RNA polymerase chain reaction tests. External laboratory blood tests to exclude other major health issues were undertaken. Results were given to participants at their next appointment, with the participants commencing DAA therapy that day if a specialist review was not required. Standard clinical data were collected, and the participants completed behavioral questionnaires. The primary outcome measures are the proportion of participants receiving GeneXpert hepatitis C RNA test, the proportion of participants commencing DAA therapy, the proportion of participants completing DAA therapy, and the proportion of participants achieving sustained virological response 12 weeks after completing DAA therapy. Results: Recruitment was completed on September 30, 2019. Monitoring visits and treatment outcome visits are scheduled to continue until June 2020. Conclusions: This feasibility study in Myanmar contributes to the evidence gap for community-based hepatitis C care in low- and middle-income settings. Evidence from this study will inform the scale-up of hepatitis C treatment programs in Myanmar and globally.

Objectives Nigeria has been badly affected by the COVID-19 pandemic, and the poor testing coverage in the country may make controlling the spread of COVID-19 challenging. The aim of this study was to assess the general public’s acceptability of SARS-CoV-2 self-testing as an approach which could help to address this gap. Setting A household-based survey was conducted in five urban and five rural local government areas in the states of Akwa Ibom, Anambra, Benue, Kaduna and Lagos, in mid-2021. Participants 2126 respondents (969 were female) participated. A five-pronged, probabilistic sampling approach was used to recruit individuals older than 17 years and available to participate when randomly approached in their households by the surveyors. A 35-item questionnaire was used to collect data on their values towards SARS-CoV-2 self-testing. Primary outcomes were: likelihood to use a self-test; willingness to pay for a self-test; and likely actions following a reactive self-test result. Results Of the total 2126 respondents, 14 (0.66%) were aware of COVID-19 self-testing, 1738 (81.80%) agreed with the idea of people being able to self-test for COVID-19, 1786 (84.05%) were likely/very likely to use self-tests if available, 1931 (90.87%) would report a positive result and 1875 (88.28%) would isolate if they self-tested positive. Factors significantly associated with the use of a self-test were having a college education or higher (adjusted Odds Ratio (AOR): 1.55; 95% CI: 1.03 to 2.33), full-time employment (AOR: 1.67; 95% CI: 1.06 to 2.63), feeling at moderate/high risk of COVID-19 (AOR: 2.43; 95% CI: 1.70 to 3.47) and presence of individuals at risk of COVID-19 within the household (AOR: 1.38; 95% CI: 1.06 to 1.78). Conclusion A majority of Nigerians agree with the concept of COVID-19 self-testing and would act to protect public health on self-testing positive. Self-test implementation research is necessary to frame how acceptability impacts uptake of preventive behaviours following a positive and a negative self-test result.
