ATLANTA — The need for drugs to prevent and treat Zika infections grows with every new patient diagnosed. The virus causes devastating birth defects and is strongly linked to a type of paralysis called Guillain-Barre syndrome.

There are currently no approved drugs against Zika; developing a new medication for any disease can take 10 to 20 years.

"The sense of urgency is enormous," said Mauro Martins Teixeira, who heads the immunopharmacology laboratory at the Federal University of Minas Gerais in Brazil. "In an emergency, everyone wants quick answers."
