  1. Epidemiology of Epstein-Barr virus infection in pre-adolescent children : application of a new salivary method in Edinburgh, Scotland.

    Article - En anglais

    Study objective-To describe the epidemiology of Epstein-Barr virus (EBV) among primary school children by testing saliva with a new EBV capsid antigen « G » antibody capture radioimmunoassay (GACRIA).

    Design-A population based sample of 7 year old schoolchildren were followed up at age 11.

    Setting-30 randomly chosen primary schools in Edinburgh, Scotland.

    Participants-552 schoolchildren.

    Measurements-Data on risk factors for infection were collected by questionnaire at ages 7 and 11.

    Saliva samples collected at age 11 were examined by GACRIA for evidence of previous infection with EBV.

    For 102 subjects, a second salivary specimen collected approximately one month after the first sample was available for testing as a measure of the repeatability of the method.

    Main results-Unequivocal results were found in 91% of samples and the repeatability of the test was good (K=0.71).

    Fifty six per cent of children had antibodies to EBV.

    In a logistic regression analysis, independent risk factors for infection were sharing a room (odds ratio 1.78,1.14,2.79), head of household's social class IV/V compared with I (odds ratio 2.87,1.08,7.34), and schools serving predominantly rented housing estates (odds ratio 2.3,1.09,4.84).

    Conclusion-This study is the first application of EBV viral capsid GACRIA to salivary samples.

    The method was successfully used to describe the epidemiology of EBV. (...)
