Health officials in Brazil say the country is "badly losing the battle" against the mosquito-borne Zika virus. Since November, more than 3,800 babies have been born in Brazil with microcephaly, a neurodevelopmental disorder, to mothers infected with the Zika virus during their pregnancy. That's compared to 146 cases of microcephaly in 2014.
