RECIFE, BRAZIL - DECEMBER 12: Juan Pedro, who has microcephaly and turned 1 year old on December 4, is held by his godmother Sinthia on December 12, 2016 in Recife, Brazil. As many of the babies with microcephaly, believed to be linked to the Zika virus, turn 1 year old in Recife, doctors and mothers are adapting and learning treatments to assist and calm the children. Many of the children are suffering a plethora of difficulties including vision and hearing problems with doctors now labeling the overall condition as "congenital Zika syndrome." Authorities have recorded thousands of cases in Brazil in which the mosquito-borne Zika virus may have led to microcephaly in infants. Microcephaly results in an abnormally small head in newborns and is associated with various disorders. The state with the most cases is Pernambuco, whose capital is Recife, and is being called the epicenter of the outbreak. (Photo by Mario Tama/Getty Images)
