This book provides an overview of norovirus, a viral infection that adversely affects the gastrointestinal system. Unfortunately, there is no specific treatment available for this illness. As such, the World Health Organization (WHO) has identified norovirus as a priority disease for vaccine development. Chapters in this edited volume cover such topics as examination methods and genome mechanisms of norovirus, and clinical and pharmaceutical developments in managing this illness.

This book contains information on various virus families, with the focus on viruses causing prevalent infections in parts of developing countries in Africa and Asia. Viral proteins play an important role in their replication and infection potential, and are the main candidates for antiviral therapy and vaccines. While some antiviral vaccines are available for quite some time (e.g. MMR), there are regions in the world still struggling with some infections. This is especially the problem in regions where the morbidity rate from viral infections among young children is high. This situation requires urgent measures to put infections under control.

Epstein-Barr virus (EBV) is a fascinating microorganism, as a "double-facetted" viral agent. After primary infection, it can persist throughout a person's lifetime in a latent form, from which it can reactivate following specific stimuli (i.e., immunodepression). Unlike other herpesviruses, EBV reactivates a countless number of times with such a high replication rate that it is unable to be controlled by conventional anti-herpesvirus drugs. Moreover, for various reasons, no vaccine is currently available in the market. This book presents a comprehensive overview of EBV, including information on its potential for oncogenic activity, its various isolates, and possible vaccine candidates.

Cervical cancer is the second most prevalent cancer among women worldwide, and infection with Human Papilloma Virus (HPV) has been identified as the causal agent for this condition. The natural history of cervical cancer is characterized by slow disease progression, rendering the condition in essence preventable and even treatable when diagnosed in early stages. Pap smear and the recently introduced prophylactic vaccines are the most prominent prevention options, but despite the availability of these primary and secondary screening tools, the global burden of disease is unfortunately still very high This book will focus on the clinical and diagnostic aspects of HPV and related disease, highlighting the latest developments in this field.

In the study of head and neck squamous cell carcinoma (HNSCC), we know that virally induced malignancies behave differently than those generated through other carcinogenic mechanisms. This paradigm extends into differences in tumor growth, treatment response and resistance, as well as invasion and metastasis. The inability to correctly diagnose and appropriately treat HNSCC at early stages has contributed to reduced survival for HNSCC patients, particularly those with HPV-negative disease. The examination of the molecular differences between HPV-positive and HPV-negative HNSCC will provide support for early diagnostic markers and guide appropriate treatment selection to improve patient care and survival.This Special Issue highlights current research efforts to understand the evolving contribution of human papillomavirus in HNSCC.

This book focuses on the “disease aspects” of classical swine fever (CSF). The epidemiological pattern of the reemergence of CSF from wild boars and its spread to neighboring domestic pigs provides useful information for policy makers. The recent advances in diagnostics and vaccines and how each type of vaccine should be appropriately used in various field situations provide useful information for practicing veterinarians and laboratory scientists, for example, whether the vaccine virus attenuated enough to not cross the placenta to avoid sequelae, how innocuous samples like serum should be cautiously treated to avoid risk of virus spread, how various genotypes of the CSF virus evolve and compete to survive in the field, and how the CSF virus molecularly manipulates normal cell biological processes for its own advantage to survive. Phylogenetic analyses help in tracing the origin of the CSF virus responsible for each outbreak. Overall, readers should be impressed by the capabilities of CFS in pigs. We hope that this book can be a useful reference for all colleagues, whether in CSF-free or CSF-affected parts of the world.

The cellular prion protein (PrPC) is expressed as a cell surface protein mainly in the central and peripheral nervous system. The discovery that prions are infectious agents changed the concept of protein synthesis in modern biology and built a bridge between the genesis of infectious and genetic diseases. This book discusses the normal function of the PrPC and its modulatory role in synaptic mechanisms. It describes the pathophysiological processes that accompany TSE - neurotoxicity, loss of anti-inflammatory protective function, neuronal death including prion-induced autophagy and apoptosis, and accumulation of PrPSc in the cytoplasm of neurons. Another aspect outlined here is that some prion diseases show strain variations that determine their development, demonstrating their key role in the development and progression of TSE.
