The NPRCs are at the forefront of research urgently needed to understand Zika virus, to help develop vaccines for it, and especially to prevent pregnant mothers from transmitting it to their unborn children.

The rapidly spreading mosquito-borne virus is strongly linked to fetal abnormalities including a neurological birth disorder called microcephaly, which results in smallness of the head, a congenital condition associated with incomplete brain development. Babies born with microcephaly have a limited life expectancy and poor brain function.

Transmitted through the bite of the Aedes aegypti mosquito – the same insect that transmits Dengue – Zika has now spread to more than 20 countries in the Americas. The Centers for Disease Control and Prevention is warning pregnant women not to travel to affected areas. Health officials in several affected areas are advising women to avoid becoming pregnant, in some cases for up to two years.

The Zika outbreak is a pandemic in progress, according to Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health (1).

The virus is mild for most people who acquire it, causing a fever, headache, rash and perhaps pink eye. The danger to pregnant mothers is the urgent concern and the main reason for the travel advisories. The virus may pass through the placenta to a growing fetus. This does not happen with the Dengue, West Nile or chikungunya viruses. Zika has been found in breast milk, but it has not yet been confirmed whether it can be passed to an infant through nursing. Immune-compromised people may also be at a higher risk of more serious illness. Zika virus can also be transmitted through sexual contact (2).

The centers have strong research programs in global infectious diseases and experience researching Dengue, HIV, Ebola, malaria, Lyme disease, chikungunya, influenza and more.

There is an urgent need for researchers to understand the pathogenesis of Zika virus infection and especially how the virus affects the fetus and causes microcephaly. This information can then be used to help develop an effective vaccine or treatment for women, so doctors can prevent more birth defects and infant deaths.

A unique aspect of the NPRCs’ Zika research is that NPRC scientists are publishing online lab notebooks for anyone to see, rather than waiting to publish their data first in a scientific journal. (Please see the Live Research Updates section below). On Feb. 10, major government funding agencies and scientific journals released a statement supporting open-data sharing during public-health emergencies such as Zika. “In the context of a public-health emergency of international concern, there is an imperative on all parties to make any information available that might have value in combatting the crisis,” the statement read.
