Com base em um programa em linguagem Fortran, utilizando a técnica de simulação em computador e através das pressuposições do Modelo Estocástico Simples de Epidemia, é estabelecida uma conjectura a respeito de valores para a taxa de infecção para a difteria, a partir de ocorrência de casos em um domicílio de cinco pessoas.

Situação vacinal infantil e características individuais e familiares do interior de São Paulo

The aim of this study was to describe and analyze individual and family characteristics of children and those of health services, as well as their relationship with the immunization status for different kinds of vaccines and doses. Three sources of information were used: records from the Municipal Health Information System, immunization charts, and interviews using closed-ended questions. The families interviewed still had one or two growing children; caretakers were usually young unemployed mothers with easy access to health services. Around 30% of them were not instructed on the vaccine being given, its reactions or when to return for the next shot. The greatest levels of tardiness occurred with the vaccines against measles (6.3%) and Haemophilus influenzae B (4.2%). It was possible to observe that tardiness or absence of vaccinations seem to have a stronger relationship with service characteristics than with population characteristics.
