The results suggest the virus could severely alter brain development in infants infected after birth, but blocking a signaling protein early on might ease certain symptoms.

Warmer weather is thought to be behind the rise in vector-borne illnesses in recent years.

The findings highlight the need for long-term monitoring of children exposed to the virus, say scientists. 

The drugs’ disruption of the microbiome makes a subsequent flavivirus infection more severe.

Studies in mice suggest that other flaviviruses, such as West Nile virus and Powassan virus, may cause birth defects, too. 

The rise occurred in areas with confirmed local transmission, according to a new CDC report. 

Signaling pathways triggered by the mother’s immune system may cause complications during fetal development.

A single receptor on natural killer cells recognizes an amino acid sequence conserved across Zika, dengue, and related pathogens.

More-sophisticated structures lend new insight into how Zika attacks the developing brain.
