It is likely that genetic factors play a role in the susceptibility to, and recovery from, COVID-19. A survey of ongoing twin research could produce findings likely to help in the prevention and management of this pandemic. This survey is followed by a review of research comparing selected features of asthmatic and nonasthmatic twins, links between twin mammals and COVID-19, and relationships between twin delivery and the three ‘Rs’. The final section of this article presents newsworthy twin-related items, some associated with COVID-19. They include a summary of the Rainman Twins film, a study of anal prints, the ‘Twins’ Irish pub, newborn twins ‘Covid and Corona’, the death of a surgeon who separated conjoined twins, and Twinco, a twin-based supply company.

遗传因素很可能在 COVID-19 的易感性和恢复中发挥作用。对正在进行的双胞胎研究的调查可能会产生可能有助于预防和管理这种流行病的发现。本次调查之后，对比较哮喘和非哮喘双胞胎的选定特征、双胞胎哺乳动物与 COVID-19 之间的联系以及双胞胎分娩与三个“R”之间的关系的研究进行了回顾。本文的最后一部分介绍了具有新闻价值的双胞胎相关项目，其中一些与 COVID-19 相关。它们包括一个摘要雨人双胞胎电影，肛门指纹研究，“双胞胎”爱尔兰酒吧，新生双胞胎“Covid and Corona”，分离连体双胞胎的外科医生的死亡，以及双胞胎供应公司 Twinco。
