Trend and seroprevalence of Epstein-Barr virus in Bahrain: 2001-2015. East Mediterr Health J. 2018 Mar 05;23(12):821-829 Authors: Farid E, Al-Biltagi M Abstract In Bahrain, adequate epidemiological information is lacking concerning the rate of EBV infection, which could be helpful in order to develop measures to protect against EBV infections. The aim of this study, was to investigate the trend of EBV infection in Bahrain over a 15-year period, 2001-2015. The EBV serological results of 10 560 patients with possible EBV infection were evaluated. Samples taken at the Salmaniya Medical Complex during 2001-2015 were included. The presence or absence of EBV viral capsid antigen (VCA) IgG, VCA IgM and EBV nuclear antigen (EBNA) IgG antibodies was recorded. Of the 10 560 samples, 10 333 were usable; of these, 86.1% were seropositive with an increasing trend of EBV infection over the study period. Primary EBV infection was found in 7.4% of the seropositive samples; of these, 47.3% were between 5 and 19 years. EBV reactivation was found in 11% of the seropositive samples; of these, 50% were > 25 years of age. The youngest seropositive patient was 11 months old. EBV is a common viral infection in Bahrain. Most primary infections occur between 1 and 5 years while most reactivation infections occur after the age of 25 years. Serial surveillance of EBV infection is needed in Bahrain. Measures to protect against EBV infections should be impleme...
