“…A χ 2 test and Fisher’s exact test were used to evaluate the differences in seroprevalence among the different groups. A reversible catalytic model ( Codeco, 2006 ) was used to assess the risk of exposure with the formula y = [ a /( a + b )] × [1 − e −( a + b ) t ], where a refers to the SCR from negative to positive; b refers to the SCR from positive to negative; and t is time. The seropositivity rates in the different defense areas were fitted according to subject age.…”

“…No início do século XX, modelos matemáticos foram inseridos na epidemiologia das doenças infecciosas com a esperança de que esses procedimentos formais aplicados à física e à química pudessem ser úteis para decifrar as complexas relações causais nas epidemias. Essa esperança é claramente indicada por Kermack & McKendrick (1927), no início de um dos seus trabalhos sobre a teoria matemática das epidemias, quando eles expressam... ..."Um dos aspectos mais salientes no estudo de epidemias é a dificuldade de encontrar um fator causal que pareça ser suficiente para levar em conta a magnitude das freqüentes epidemias de doenças que assombram quase todas as populações" (Codeço, 2006).…”

“…Estes modelos são do tipo determinístico e descrevem a interação da população de suscetíveis coma as "forças" de infecção. Muench também sugeriu um procedimento de ajuste destes modelos aos dados empíricos (Struchiner, 2006;Codeço, 2006).…”
