Viruses often cause isolated or recurrent infections. Moreover, they are often the leading culprit in the pathogenesis of other oral pathogens, particularly of certain oral malignancies. In sick patients, oral infections are among the leading cause of morbidity while systemic viral infections caused by oral infections are the significant cause of mortality amongst sick patients, particularly in palliative care patients. This chapter discusses viral infections, with particular emphasis on the infections caused by the herpes virus family. In this chapter, two of the most common types of herpes virus are examined together with the oral infections they cause. One of the two types of herpes viruses is the herpes simplex virus (HSV) which causes primary herpetic gingivostomamsis, herpes labialis, and herpes simplex infections in immunocompromised patients. The second type of herpes virus is the varicella zoster virus, the pathogenic virus of primary varicella zoster infections/chicken pox and secondary varicella zoster infections/shingles. The chapter concludes with a discussion on the other types of herpes viruses such as Epstein-Barr virus and Cytomegalovirus.
