Zika may have led to fewer babies in Rio

摘要

Brazil's Zika outbreak may have prompted a drop in the number of live births in Rio de Janeiro in late 2016. Between October 2015 and January 2016, roughly 4000 babies were born in Brazil with microcephaly -abnormally small heads, a condition linked to infection with the Zika virus during pregnancy. In June, the World Health Organization recommended that women in affected areas delay getting pregnant to avoid the risk of having babies with birth defects.
