PRI's The World: 01/27/2016

From Brazil, we hear how authorities are battling Zika, the mosquito-borne virus that's been linked to severe birth defects. It's all happening as the country prepares for Carnival and the Summer Olympics. Also, Italy is the last country in Western Europe not to permit civil unions or same-sex marriage, but tomorrow, the Italian senate debates legislation to change that. Plus, we hear from a Persian rug dealer in LA who's hoping for a boom in business with the end of sanctions on Iran.
