[Measles outbreak in Tormaleo (Asturias)].
BACKGROUND
We have studied a measles outbreak in the town of Tormaleo. The number of cases went beyond all the expectations and tendencies of the disease in the area. As a great proportion of the cases were older children, we thought it appropriate to inquire into it, as well as to evaluate the vaccine effectiveness.


METHODS
The research was carried out retrospectively, at the end of the epidemic, in a cohort retrospective study. The children who had not suffered the disease or had not been vaccinated were considered as the group at risk, with no immunological protection, and the vaccinated ones as the protected immunized group. It is assumed that practically the whole collectivity gets into contact with the virus in a measles epidemic. The affected population consisted of 92 children: 41 males and 51 females. A total sum of 36 cases of measles was clinically diagnosed: 13 boys and 23 girls.


RESULTS
The highest incidence came from the age group of 12, 13 and 14 years old. The different measures of frequency, epidemiological risk parameters and global effectiveness of the vaccine were calculated. The incidence, among the nonvaccinated ones, was 84%, and 15% among the vaccinated ones with a global effectiveness of the vaccine of 82%.


CONCLUSIONS
The effectiveness of the vaccine is similar to the one found in other studies. The risk of suffering. The disease for non-vaccinated people is extremely high.
