Daniele Ferreira dos Santos holds her son Juan Pedro, who was born with microcephaly, outside her house in Recife, Pernambuco state, Brazil, Jan. 26, 2016.
Around the fifth month of her pregnancy, Daniele Ferreira dos Santos fell ill with a high fever and angry red splotches on her skin. She soon recovered.
Weeks later, when she went to the hospital for a prenatal exam, the news was horrific: The baby she was carrying likely had a severe brain injury. When Juan Pedro Campos dos Santos came into the world in Dec., the circumference of his head was just 26 centimeters (10.2 inches), about 20 percent smaller than normal.
Santos was never diagnosed with Zika, but she blames the virus for her son's defect and for the terrible toll it has taken on her life. Thousands of confirmed or suspected cases of microcephaly in Brazil may be connected to the virus.
