"It turns out the Zika virus is very similar to its relatives in the flavivirus family, including dengue, whose structure has been well studied. But a group of proteins that sit on the surface of the virus, known as envelope E glycoproteins, are distinctively different. These proteins are involved in how the virus enters cells in the infected body. They could potentially explain how the Zika virus is able to attack nerve cells, and why it's causing neurological syndromes like Guillain–Barré, and developmental conditions like microcephaly, in which a baby is born with an abnormally small head."
