SEATTLE -- On the heels of the World Health Organization declaring a public health emergency related to the Zika virus, local scientists said they are already working on a cure. And if they're able to treat Zika, it could also mean a cure for viruses ranging from West Nile to Ebola, to the common cold.

Scientists at biotech company Kineta and the University of Washington are developing the compound. Just like antibiotics treat bacterial infections, their antiviral drug would fend off a range of viruses.
