“…In the current study, EBV was detected in18 out of 19 (95% ) in eBL and in 42 out of 60 (70%) in control cases (significant association , p < 0.05) ( Fig. 2) and in 8 out of 41 (20%) of the sBL (no significant association , p > 0.05), ( Fig.3).These findings were consistent with previous studies from United States (1,2) that found EBV was present in the majority of endemic cases of BL (up to 100%) and in only 15% to 30% of sporadic cases and also similar to other studies from Europe (29) , northeast of Brazil (17,33) , Africa (34) ,Argentina &Chile (35,36) , and Iran (8) . In contrary to our results, studies from Southeast and Central West regions of brazil (7,35,37,38) that obtained different frequencies of association between BL and EBV, varying from 50% to 72%.…”
