Religious leaders are among those grappling with how best to respond to the Zika virus, which is rapidly spreading throughout Latin America. The World Health Organization has declared the virus a global public health emergency. Experts have linked the virus to cases of microcephaly—babies born with small heads and underdeveloped brains. Some officials have provoked controversy by suggesting that until the virus is contained, Latin American women should not become pregnant. The outbreak has also reinvigorated a debate on the restrictive abortion laws in Brazil and other countries.
