Offering a thorough, accessible overview of the basic science and clinical data regarding the virus that causes COVID-19, Molecular Biology of SARS-CoV-2 is an excellent resource for researchers, clinical scientists, physicians, and students. This volume offers in-depth, extended content that originated with Drs. Roberto Patarca’s and William A. Haseltine’s chapter in The COVID-19 Textbook, edited by Dr. Haseltine and Dr. Patarca.
