[The seroepidemiology of the varicella-zoster virus in children and adolescents].
OBJECTIVE
To know the sero-protection level existing of varicella-zoster virus in a population of children and adolescents from Madrid.


METHODS
To carry out this work we have had a total 560 serum from children and adolescents between 1 and 15 years old. Later to detect the title of antibodies against the varicella zoster virus (IgG VZV), we used enzymo immuno-analysis (PLATEST).


RESULTS
The 96.5% of them were positive. Distributing this percentage in a similar way for every age, we get 100% at 8, 9, 10, 11 and 15 years old; 97.5% at 5, 6, 7, 12 and 13 years; 95% at 14 years old; 92.5% at 4 years old and 85% at 1 years old and 84% at 2 years old.


CONCLUSIONS
The prevalence gradually increases with the age, from 20% at 1 year old to 100% at 15, finding the smallest prevalence in 84% to reach rapidly 100%.
