Human Respiratory Viral Infections

The viruses that cause respiratory viral infections encompass parainfluenza viruses, respiratory adenoviruses, influenza viruses and respiratory syncytial virus (RSV). These spread directly through coughing or sneezing, which results in the transmission of viruses when they are inhaled. They can also spread indirectly by coming in contact with contaminated surfaces, hands, handkerchiefs, toys, etc. Some common symptoms of respiratory viral infections are fever, headache, chills, loss of appetite, body ache and weakness. There are various complications associated with respiratory viral infections, including pneumonia, tonsillitis, bronchitis and laryngitis. Their treatment involves administration of antiviral agents, such as amantadine and ribavirin. This book provides a detailed understanding of human respiratory viral infections. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of study. The book will prove to be immensely beneficial to students and researchers engaged in the study of these infections.
