Over 50% of known flaviviruses have been associated with human disease. The Flavivirus genus constitutes some of the most serious human pathogens including Japanese encephalitis, dengue and yellow fever. Flaviviruses are known for their complex life cycles and epidemic spread, and are considered a globally-emergent viral threat.Pathogenesis and Immunity, the second volume of The Flaviviruses, examines the processes by which the flaviviruses cause disease, the different cytopathic effects and the associated immunopathological responses produced in their hosts.
