No cases of the Zika virus have originated in the U.S., but the possibility of it spreading north exists so doctors hope to get a better handle on the disease and work toward a cure.
"This virus has really exploded, transmitting throughout Central America, South America, and its arrival in the Americas, and the link to the congenital malformations has really caused concern that we're seeing today," said Dr. Lisa Maragakis with Johns Hopkins Infection Prevention.
