Mass gathering event restrictions were part of mitigation measures during the COVID-19 pandemic that were lifted as prevalence decreased and after vaccination rollout. We explored SARS-CoV-2 antigen rapid diagnostic test acceptability and positivity in community settings in Cameroon. In August-October 2022, community workers sensitized and referred individuals for COVID-19 testing to nearby testing points in Douala and Yaoundé. Participants consented to SARS-CoV-2 antigen rapid diagnostic testing, a survey, or both components. We describe the positivity rate, COVID-19-related history, and Likert-scale testing perceptions. Factors associated with testing acceptance were analyzed using logistic regression. Overall, 20.5% (2,449/11,945) of sensitized individuals visited testing points, and 1,864 (76.1%) were enrolled; 50.6% accepted the survey and testing (46.0% accepted survey only). Seven (0.7%) of 1,006 individuals tested positive. Most (71.8%; 1,292/1,800) considered community testing more accessible than hospital-based testing. Individuals accepting versus refusing testing differed in perceived COVID-19 risk (67%, 49%; P <0.001), belief in accurate test results (79%, 47%; P <0.001), and ability to test easily (96%, 55%; P <0.001). Males (adjusted odds ratio [aOR]: 1.26 [1.04-1.53]) and those over 50 years (aOR: 1.9 [1.4-2.7]), with symptoms (aOR: 1.80 [1.30-2.50]), and at least partial vaccination (aOR: 0.76 [0.58-0.99]) were significantly associated with test acceptance. Refusal reasons included lack of perceived need for testing (33.8%) and testing discomfort (26.3%). Although community-based testing was generally perceived as important, actual testing uptake was low. In future pandemics, community testing should be optimized by addressing misinformation, offering alternative testing modalities for greater comfort, creating demand, and tailoring approaches to maximize testing uptake.
大规模聚集活动限制是新冠疫情期间缓解措施的一部分，随着疫情流行率下降以及疫苗接种推广而解除。我们在喀麦隆的社区环境中探讨了新冠病毒抗原快速诊断检测的可接受性和阳性率。2022年8月至10月，社区工作人员对个人进行宣传，并将其转介到杜阿拉和雅温得附近的检测点进行新冠检测。参与者同意进行新冠病毒抗原快速诊断检测、一项调查或两者。我们描述了阳性率、与新冠相关的病史以及李克特量表测试认知。使用逻辑回归分析与检测接受度相关的因素。总体而言，20.5%（2449/11945）的被宣传个人前往检测点，1864人（76.1%）登记；50.6%接受了调查和检测（46.0%仅接受调查）。1006名接受检测的个人中有7人（0.7%）呈阳性。大多数人（71.8%；1292/1800）认为社区检测比医院检测更容易获得。接受检测与拒绝检测的个人在感知到的新冠风险（67%对49%；P<0.001）、对检测结果准确性的信念（79%对47%；P<0.001）以及检测的便捷性（96%对55%；P<0.001）方面存在差异。男性（调整后的优势比[aOR]：1.26[1.04 - 1.53]）、50岁以上人群（aOR：1.9[1.4 - 2.7]）、有症状者（aOR：1.80[1.30 - 2.50]）以及至少部分接种疫苗者（aOR：0.76[0.58 - 0.99]）与检测接受度显著相关。拒绝原因包括认为没有检测需求（33.8%）和检测不适（26.3%）。尽管基于社区的检测总体上被认为很重要，但实际检测参与率较低。在未来的疫情中，应通过解决错误信息、提供更舒适的替代检测方式、创造需求以及量身定制方法以最大限度提高检测参与率来优化社区检测。
