"Scientists Are Bewildered By Zika’s Path Across Latin America"

"RIO DE JANEIRO — Nearly nine months after Zika was declared a global health emergency, the virus has infected at least 650,000 people in Latin America and the Caribbean, including tens of thousands of expectant mothers.

But to the great bewilderment of scientists, the epidemic has not produced the wave of fetal deformities so widely feared when the images of misshapen infants first emerged from Brazil.

Instead, Zika has left a puzzling and distinctly uneven pattern of damage across the Americas. According to the latest U.N. figures, of the 2,175 babies born in the past year with undersize heads or other congenital neurological damage linked to Zika, more than 75 percent have been clustered in a single region: northeastern Brazil."
