Gostaria da opinião de vocês.
Em frases como:

"Studies based on data for the late 1980s show a direct and positive relationship between the level of education and the prevalence rate."

"(...) then it is unlikely that a clear pattern will be discernible between the level of education and the HIV prevalence rate."


Vocês acham que "prevalence" pode ser traduzida como "incidência"?

obrigada! bom domingo a todos!
