EBV infection as detected by in situ hybridization to the abundantly expressed non-polyadenylated EBER RNAs has been demonstrated in high-grade severe dysplastic and carcinoma in situpreinvasive lesions in the nasopharynx, but not in low-grade disease or histologically normal nasopharyngeal epithelium [35][79].

There are several well-described forms of EBV latency, each of which nasofarngeo virus uses at different stages of the viral life cycle and which are also reflected in the patterns of latency observed in various EBV-associated malignancies [2][5].
