The Zika puzzle

Experts hope large-scale study of pregnant mothers sheds light on Zika

By WITW Staff on June 22, 2016

On Tuesday, the U.S. and international researchers announced the launch of a large-scale study tracking 10,000 pregnant women across Latin America and the Caribbean from the beginning of their pregnancies through births in order to learn more about how the Zika virus affects developing infants.

While the Centers for Disease Control and World Health Organization have confirmed that Zika causes birth defects, the information available to experts about the virus remains very limited — there’s little to no data on whether women face different risk factors if they contract the disease earlier or later in their pregnancy, for example. By monitoring the women monthly and collecting blood and other samples, experts hope to learn more about a variety of factors that could affect outcomes for developing fetuses. “A mother’s environment may be an important part of the Zika virus puzzle,” explained Linda Birnbaum, director of the National Institute for Environmental Health Sciences, one of the institutes taking part in the study.

The Obama administration has diverted $500 million from other health programs to fund the study, said Dr. Tony Fauci, head of the National Institute of Allergy and Infectious Diseases. “However,” he cautioned, “we cannot continue or finish the study until we get additional money from Congress.” Obama had asked Congress for $1.9 billion to study and fight the disease, but was denied.
