Blue Shadow Virus

The Blue Shadow Virus was a deadly disease that spread like a plague in the galaxy many years before the Clone Wars. Waterborne in its original form, the majority of carbon-based lifeforms were susceptible to it. Although the virus was eventually eradicated, during the Clone Wars, Doctor Nuvo Vindi of the Confederacy of Independent Systems re-engineered an airborne strain of the virus on Naboo. He attempted to spread it across the planet, but was stopped by the Galactic Republic and Jedi Order.
