The discovery of KSHV in 1994 was a historical landmark in tumor virology and human cancer research. KSHV's subsequent identification as a cause of Kaposi sarcoma and its association with primary effusion lymphoma and multicentric Castleman disease soon attracted the attention of hundreds of research laboratories and motivated thousands of virologists and oncologists to switch their research directions. To date, PubMed has collected nearly 5000 papers on KSHV from numerous journal publications throughout the world. These studies indicate that the global fight against human cancers will continue to receive great support from our tremendous efforts in searching for new tumor-causing viruses and in understanding the basic biology of tumor viruses. To celebrate the 20th year of KSHV's discovery, I am very proud to be an invited Guest Editor for a Special Issue on KSHV in Viruses and am happy to assemble all published articles from the Special Issue into this book, Kaposi Sarcoma Associated Herpesvirus.
This book is a reprint of the special issue that appeared in the online open access journal Viruses (ISSN 1999-4915) in 2014.
