Organization says the spike might be largely the result of an increase in diagnoses of microcephaly — but not everyone agrees.

Researchers at the body responsible for monitoring birth defects in Latin America are questioning the size of an apparent surge in the number of Brazilian children born with 'microcephaly' — abnormally small heads and brains.
Alarm is growing about a reported rise in suspected cases of the rare condition, which has been tentatively linked to the rapid spread of the Zika virus through the Americas. But Jorge Lopez-Camelo and Ieda Maria Orioli, from the Latin American Collaborative Study of Congenital Malformations (ECLAMC), say that the surge might largely be attributed to the intense search for cases of the birth defect, and misdiagnoses, because of heightened awareness in the wake of the possible link with Zika.
This ‘awareness’ effect is well known and inevitable, they say, and must be revealing cases that would have gone unnoticed under normal circumstances. They also say that a high rate of misdiagnoses among reported cases is likely because the diagnostic criteria being used for microcephaly are broad.
