In 2020 we lost Noel Rose, co-editor of the classic Infection and Autoimmunity. To honor and respect his work, a group of experts in the field have taken the initiative to make this book perpetual. The third edition of Infection and Autoimmunity updates all the recent and leading papers on infection and autoimmunity, in addition to a dedicated section on to the correlation between SARS-CoV-2 infection and autoimmunity. From the very beginning of the COVID-19 pandemic, numerous papers have been published, including studies conducted by the editors and authors of the book, on COVID-19 and autoimmunity, and therefore this knowledge has been incorporated into this new edition. The addition and extended coverage on SARS-CoV-2/COVID-19 and autoimmunity are pivotal for the third edition of the book due to the COVID-19 pandemic. Medical students and practitioners, as well as academic staff in medical schools globally, are enthusiastic in searching for better understanding of the correlation between infection and autoimmunity in general, and the long-term effects of SARS-CoV-2 and COVID-19 on the immunce system in particular, especially in terms of autoimmunity related to the virus.
