[Evolution of the prevalence of hepatitis A antibody in Seville].
OBJECTIVE
To find the evolution of the prevalence of the Hepatitis-A antibody in Sevilla.


METHODS
Observational study of a crossover type. Comparison of results in 1995 with those from a similar study in 1981.


METHODS
Health Area covered by Sevilla's University Hospital Virgen del Rocío.


METHODS
Aliquots of serum from patients without Hepatitis were obtained from the hospital's clinical analysis laboratories.


RESULTS
The sera were analysed in the Nuclear Medicine laboratory of the HUVR. 37.96% (62.74% in 1981) of the individuals surveyed were HA-positive. Prevalence increased with age: in the over-24s it was over 75% (90% in 1981). The differences between the two sets of results was significant (p < 0.001).


CONCLUSIONS
Hepatitis-A infection is becoming less common in Andalusia, which can now be considered a low-incidence area.
