为了抗击2019年冠状病毒病（COVID-19）的大流行，许多政府设立了电话热线，以预先筛查潜在病例。这些热线一直在努力应对大量呼叫者，导致等待数小时，甚至无法与卫生当局取得联系。Symptoma是一款从症状到疾病的数字健康助手，可以区分2万多种疾病，准确率超过90%。我们使用一组不同的临床病例结合COVID-19病例报告来测试症状识别COVID-19的准确性。结果表明，临床病例中，症状能准确区分COVID-19的比例为96.32%。在仅考虑COVID-19症状和风险因素时，仅出现三种体征时，症状就能100%识别出感染者。最后，我们证明了Symptoma的准确性远远超过了网上广泛使用的简单的“是-否”问卷。总之，Symptoma在系统识别COVID-19病例方面提供了无与伦比的准确性，同时还考虑了2万多种其他疾病。此外，Symptoma还支持36种语言的自由文本输入，以及针对特定疾病的后续问题。综上所述，这些结果和可获得性使Symptoma有可能成为全球抗击COVID-19的关键工具。症状预测器可在https://www.symptoma.com免费在线获取。
To combat the pandemic of the coronavirus disease 2019 (COVID-19), numerous governments have established phone hotlines to prescreen potential cases. These hotlines have struggled with the volume of callers, leading to wait times of hours or, even, an inability to contact health authorities. Symptoma is a symptom-to-disease digital health assistant that can differentiate more than 20,000 diseases with an accuracy of more than 90%. We tested the accuracy of Symptoma to identify COVID-19 using a set of diverse clinical cases combined with case reports of COVID-19. We showed that Symptoma can accurately distinguish COVID-19 in 96.32% of clinical cases. When considering only COVID-19 symptoms and risk factors, Symptoma identified 100% of those infected when presented with only three signs. Lastly, we showed that Symptoma’s accuracy far exceeds that of simple “yes–no” questionnaires widely available online. In summary, Symptoma provides unparalleled accuracy in systematically identifying cases of COVID-19 while also considering over 20,000 other diseases. Furthermore, Symptoma allows free text input, furthered with disease-specific follow up questions, in 36 languages. Combined, these results and accessibility give Symptoma the potential to be a key tool in the global fight against COVID-19.
