Lab technician Elisangela Dias at work in a laboratory at the Oswaldo Cruz Foundation, a federally funded research institution breeding the Aedes aegypti mosquito for reseach. The insect carries the Zika virus which is thought to be responsible for microcephaly in unborn children.
The mosquito-borne Zika virus continues to spread in Brazil, alarming health officials and expecting mothers that their babies will be born with abnormal brain development called microcephaly. While researchers have yet to make a connection, Brazil has the highest number of babies born with mircocephaly - the most cases in Recife, Pernambuco - from mothers who tested positive to the Zika virus. There are about 3,530 suspected cases of zika-related microcephaly in Brazil.
