**3.4 Relationship between the number of EBV DNA copies and clinical complaints**

Further, a correlation analysis was carried out to reveal the relationship between the numbers of EBV DNA copies in saliva samples before the start of IFN-γ therapy with the severity of clinical complaints in patients. The results are shown in **Table 8**.


**Table 8.**

*Influence of the number of EBV DNA copies on the severity of clinical complaints in patients with СEBVI (N = 51).*

Thus, the number of copies of EBV DNA in saliva samples affects the development of weakness, sore throat, and arthralgia in patients with CEBVI.
