the suspected epicenter of the phenomenon.

of cases and birth defects in Brazil in the past year —
suspected to exceed more than 4,100, making that nation the
epicenter of the epidemic — has prompted health officials there to warn pregnant women or those thinking
of becoming pregnant to take precautions or consider delaying pregnancy.
