Childhood infections as predisposing factors to developing psoriasis vulgaris into early adulthood

We demonstrate, for the first time, the effect of exposure to infections during the first years of life and the subsequent development of psoriasis extending into early adulthood. Our study indicates that early exposure to infections may influence the development of the adaptive immune system during formative years. This modulation is evidenced by the higher incidence of psoriasis observed in early adulthood, several years after the initial exposure.
