JOAO PESSOA, Brazil — U.S. and Brazilian health workers seeking to determine if the Zika virus is causing a surge in birth defects ran into the chaotic reality of northeastern Brazil on their study’s first day Tuesday. Traffic and logistical problems shredded their schedule, delaying or preventing meetings with mothers and babies.
The plan conceived in the air-conditioned halls of Brazil’s Health Ministry and the Atlanta headquarters of the Centers for Disease Control and Prevention had seemed simple:
Eight teams of “disease detectives” are looking to enroll about 100 mothers of babies with microcephaly, a rare defect that causes newborns to have unusually small heads and damaged brains. They also want to sign up two to three times as many mothers of babies without the birth defect, born in the same area at around the same time.
