Abstract:  Objective To study the epidemic characteristics and disease spectrum of Epstein-Barr virus (EBV) infected children in Zhongshan region, Guangdong province. Methods Clinical data from the children with positive EBV-DNA detected by real-time fluorescent quantitative PCR between 2011 and 2013 was retrospectively analyzed. Results A total of 409 cases were detected with EBV-DNA positive from 3402 cases, with a total positive rate 12%, and the positive rate is 8.1% in 2011, 10.4% in 2012, 19.5% in 2013, there were significant differences among positive rate (χ2=6804.00, P<0.05). There was no statistically significant difference in the positive rate of EBV-DNA between different gender (χ2=0.239, P>0.05) and different age groups (χ2=136.96, P<0.05). The positive rate of pre-school group is the highest. EBV infection can cause multiple system diseases. The most common disease caused by EBV infection was infectious mononucleosis (61.6%), followed by respiratory tract infection (26.7%), neck lymphadenitis (3.4%), idiopathic thrombocytopenic purpura (2.4%), etc. Among the 409 cases of EBV infection, the concurrent other pathogen specific IgM positive cases as MP-IgM positive (n=79), CP-IgM positive (n=47), Parvovirus B19-IgM positive (n=20), HSV-IgM positive (n=11), CMV-IgM positive (n=10), and RV-IgM positive (n=4) were found. Conclusions Infectious mononucleosis is the leading disease in children infected by EBV in Zhongshan region, the annual positive rate is increasing. Multiple pathogen specific IgM may be detected positive in children with EBV infection, which should be interpreted in combination with clinical status.
